On the afternoon of August 25, 2020, enterprises in Yueqing District of Zhejiang, including our Yulin Electronics Co., LTD., participated in the launching ceremony of the hundred Regiment battle in the Procurement festival in September.Due to the impact of coVID-19 this year, international trade has been severely impacted. Therefore, through this competition, we hope to boost the morale of foreign trade enterprises and strive to achieve this year’s goals.

The companies present are divided into three legions, one legion, Wolf Warrior and Reaper legion.This hundred regiments war, not only for their own companies for their own fight, but also for the whole army.

The launch conference is divided into two parts.

The first part was a warm-up for the group. We played a game of bridge building.Let the last person in the line climb over our bodies. After climbing, the last person in the line will stand at the front of the line, bow, and join the bridge. Then let the last person in the line climb, and repeat, so that the line moves forward little by little until the end.As can be seen from the picture, there are both boys and girls in this team. In fact, this team is very tired and painful. Even when people climb over, the girls’ knees will fall to the ground, but we still hold on to the end.Just like the situation this year, even though it is very difficult, we still hold on and hope that the epidemic will end soon and the whole world can return to its original life.

The second part is to explain the rules and objectives of this activity.

The measurement index of this activity is mainly the quantity and amount of credit guarantee orders of Alibaba. I hope you can see here. If you are interested in our products, please feel free to contact us and give us more support.

Our company’s target is to guarantee the order quantity of 120 and the amount of 300 thousand DOLLARS.

In the next month, we will work hard to finish the task, come on, come on, come on!

He is busy at work and stressful in life, and often carries out some team building activities, which is of great significance for both the enterprise and the individual. The purpose of the organization of corporate team building activities is for employees to work better and more passionately, and to improve work efficiency in the team. Good team building can promote awareness and understanding between people, promote emotions between teams, enhance team spirit and teamwork ability, stimulate employee enthusiasm, and enhance team cohesion.

Specific content of team building activities:

At nine o’clock in the morning, the company staff gathered downstairs.

After that, we organized the team members to get on the bus to the destination in an orderly manner. We played an ice-breaking game on the bus. The team members introduced themselves one by one so that they could get acquainted with each other, break down barriers, and get closer.

Before reaching the destination, we took a five-kilometer hike. It was very difficult to walk because of the weather. Although it was very tiring on the way, some people supported each other, and some people behind pushed the people in front to walk, no matter what, no one was there. Give up, everyone insisted on walking down.

After reaching the destination, we started a series of activities today. The first is standing in the military posture. Standing in the military posture allows us to be disciplined and improve our self-awareness.

Since the team members did not gather within the specified time and delayed the gathering time, the punishment they received was a “healthy gift package”-squatting down is not a big deal for boys, but for girls, it’s a bit difficult, But fortunately, it can be regarded as merciful.

Next is the lunch time. We prepared ingredients, meat, fruits, various seasonings and side dishes in advance. Each group of people showed off their magical powers, showed their skills, and took out their own good dishes. Those who don’t know how to cook are also positive. I helped out. Two hours passed happily and harmoniously in this way. Each group also prepared the finished products of each group. It may be because it was the result of their own labor. Everyone was very happy. The meal was very fragrant. After heavy rain, although the weather was very cold, it did not affect our good mood at all.

After a pleasant morning, the following is the activity project: First, I did a simple dance to warm up. Although it doesn’t look very beautiful, everyone finished it with laughter.

The second is the real activity project, Yandang Mountain Canyon Rafting! Yandang Mountain is a tourist attraction near our company, and it is also the first batch of 5A-level scenic spots in the country. Yandang Mountain has both the peculiar mountains and peaks and the agility of springs and waterfalls. Among them, the world-famous Dalongqiu, with a waterfall of more than 190 meters high, is awe-inspiring by its majestic momentum, changing forms, and fascinating scenery. We were rafting the canyon at the foot of Yandang Mountain. After putting on life jackets in an orderly manner, each group of people went into the water one after another. The water spilled during the war also broke the last gap in our hearts, and everyone’s faces were filled with smiles. The rafting hasn’t started, one by one has become a dreadful. The next rafting was exciting and layered, with turbulent currents, deep caves, and secluded pools… the rafting ended with a scream and exclamation.

After the canyon rafting is over, our team building this time is also over. Through this team building activity, some employees feel that going through the cave has increased the cohesion between us, and some employees feel the cooking process, which makes everyone more Like brothers and sisters, the atmosphere is more like a home. Some employees feel that the five-kilometer training is very tiring, but it makes themselves more aware of the limits of their bodies. It is a good experience. Some employees feel that our projects help each other at the end. It touched themselves, and some employees felt that the icebreaking game has drawn the distance between each other, and it has also increased convenience for future work. This team building activity has shortened the distance between employees and deepened the friendship between employees. Improve the cohesion of the team, make everyone better relax after stressful work, let employees fully realize the richness of corporate culture and find a sense of belonging, improve their combat effectiveness, and make employees more passionate and better engaged In the next step of work, a meaningful team building activity is always unforgettable.

By popular demand, we now have rugged metal buttons with a full color RGB LED ring light! These chrome-plated metal buttons are rugged, but certainly not lacking in flair.

This is a 19mm Momentary version of the RGB pushbutton. Simply drill a 19mm hole into any material up to 0.45″ thick and you can fit these in place – there’s even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a plastic RGB LED ring. On the back there are 4 metal contacts for the RGB LED ring (one anode and 3 cathodes for each red, green, and blue) and 3 spade contacts for the switch.

To use the RGB LED: Power the anode at 3-6V and light up the red, green, and blue LEDs by pulling their designated contacts to ground as you desire – there’s a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 1K ohm resistor in series with the LED cathodes to keep the LED current at around 20mA. You can PWM the RGB pins to make any color you like.

And we can do it in 3~380v if you need we adjust the voltage for you.

For the colors, one rgb pushbutton switch can have 7 different colors.

Red, Green,blue,Red+Green =Yellow color.

Red +Green+Blue = White color.

Red + Blue = purple color

Green+Blue =Light Blue

To use the switch: There is one SPDT switch inside the button. Looking at the bottom of the switch, the common contact is the one to the left of the C. Above it are two spade contacts, one labeled NO (normally-open) and one labeled NC (normally-closed). When you press the button, the NO contact will close to the common contact, and the NC contact will open from the common.

The switch and LED are electrically separated, so to change the color, use a micro controller to both read the contact pins and toggle the color control pins.

Horn is car audio signal device. When the car is driving, drivers have to send out necessary audio signals according to need and Regulations, warn pedestrians and get other vehicles attention, ensure traffic safety, At the same time, it is also used to Push forward and transmit signals. The main reasons for the speaker don’ t ring is lack of battery power storage, horn relay and button damage, horn damage, etc..

Rocker switches are also called rocker switches. Its structure is the same as that of a toggle switch, except that the handle of the button is replaced with a boat shape. Rocker switches are often used as power switches for electronic equipment. Their contacts are divided into single-pole single-throw and double-pole double-throw. Some switches also have indicator lights.

Switch type

Single pole single throw: 1 moving contact and 1 static contact. Only 1 channel

Single pole double throw: 1 moving contact and 2 static contacts, (the static contacts on both sides can be connected respectively)

Double pole single throw, 2 moving contacts and 2 static contacts, with 2 channels

Scope of application

Rocker switches are used in water dispensers, treadmills, computer speakers, battery cars, motorcycles, ion televisions, coffee makers, power strips, massage machines, etc., and are mainly used for household appliances.

The test method of ship switch life

Mainly test the number of opening and closing until it is damaged. If you do not need to manually use a small motor to drive the eccentric opening and closing switch, use a counter to record the number of times! This switch requires safety certification is necessary. If the product is sold in China, use CQC. If it is sold abroad, it depends on the specific country where it is sold, such as the United States UL, Canada CUL, and European countries have VDE, ENEC, TUV and other safety certifications.

Fault problem

The rocker switch is a very common kind of red light when it is switched on. Sometimes it can’t be turned off, just can’t bounce back, and it often jumps to the air switch failure

The method to solve the fault:

There is a metal piece inside the rocker switch with a spring fulcrum in the middle. The spring displacement and the aging and deformation of the plastic bracket make the switch inflexible. You can disassemble it after power off and have a look. If the plastic part is not damaged, it may be restored. The neutral wire inside the switch is straight through and has nothing to do with the switch components. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral wire of the switch is damaged. You can cut off the damaged section and reconnect the wiring. Pay attention to the insulation to ensure . It may also be that there is a short circuit on the indicator light pin, just re-wire.

Method of choosing

1. Is the certification complete?

Whether the waterproof rocker switch is fully certified, selected environmentally friendly materials, passed the relevant ROHS regulations, and has SGS certification; it has VDE/DEMKO/KEMA (currently using EU ENEC), UL/CSA and other certifications, only Arcolectric waterproof rocker switches can do well To the certification is complete.

2. IP waterproof standard

The sealing performance of the waterproof rocker switch exceeds the standard. When paired with related accessories, it can reach IP65, IP66, IP67 or even IP68 waterproof rating.

3. Design issues

Whether the waterproof rocker switch has reasonable design, long service life, high temperature resistance and high current impact resistance, these should be considered.

Precautions for use

The specific application of the waterproof rocker switch is restricted by many factors, such as: installation method and product installation direction, air flow, pressure difference acting on the product, fluid rebound strength and working voltage; etc. Even if the Arcolectric waterproof boat switch with excellent sealing performance, its sealing technology has reached the leading level, it also means that the switch is completely sealed, and it is necessary to prevent the intrusion of corrosive gases or substances.

Synonyms Temperature control switch generally refers to thermostat

Thermostat refers to a series of automatic control components that produce some special effects and produce turn-on or turn-off actions according to the physical deformation inside the switch according to the temperature change of the working environment. It is also called temperature control switch and temperature protector. , Temperature controller, referred to as thermostat. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the desired temperature and energy saving effect.

The application range of thermostats is very wide. According to different types of thermostats, they are used in many products such as household appliances, motors, refrigeration or heating.

working principle

Its working principle is to automatically sample and monitor the ambient temperature through the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit starts, and the control hysteresis can be set. If the temperature is still rising, when it reaches the set over-limit alarm temperature point, the over-limit alarm function will be activated. When the controlled temperature cannot be effectively controlled, in order to prevent the destruction of the equipment, the tripping function can also be used to stop the equipment from continuing to operate. Mainly used in various high and low voltage switch cabinets, dry-type transformers, box-type substations and other related temperature applications used in the power sector.

Wiring method

Look carefully at the three feet on the thermostat. They are all replaced by English letters and numbers, which are H (6), L (3), and C (4).

H(6) is connected to the brown wire, which is the live wire of the power supply;

L(3) is connected to the gray wire, which is the live wire of the lamp;

C(4) is connected to the white wire, which is the hot wire of the compressor.

Control Method

There are generally two control methods; one is controlled by the temperature change of the object to be cooled, mostly using a vapor pressure temperature controller, and the other is controlled by the temperature difference of the object being cooled, mostly using electronic temperature Controller.

It adopts fuzzy control technology such as PID control, P (Proportional) proportional + I (Integral) integral + D (Differential) differential control.

Sudden jump thermostat

The bimetallic snap-type thermostat is a kind of bimetallic strip after a fixed temperature as a heat-sensitive reaction component. When the temperature of the main part of the product rises, the heat generated is transferred to the bimetallic disc and reaches the action temperature setting. Quick action, the function of the mechanism is to open or close the contact; when the temperature drops to the reset temperature setting, the bimetallic strip quickly returns to its original state, making the contact close or open, achieving the purpose of connecting or disconnecting the circuit, thereby Control circuit.

The models of various sudden jump thermostats are collectively referred to as KSD, such as KSD301, KSD302, etc. The thermostat is a new type of bimetallic thermostat. It is mainly used for various electric heating products with overheat protection. The fuse is connected in series, and the sudden jump thermostat is used as the primary protection. The thermal fuse acts as a secondary protection when the sudden jump thermostat fails or fails to cause the heating element to overheat, effectively preventing the burning of the heating element and the resulting fire accident.

Liquid expansion thermostat

It is a physical phenomenon (volume change) that causes the substance (usually liquid) in the temperature sensing part of the thermostat to expand and contract when the temperature of the controlled object changes, and the bellows connected with the temperature sensing part expands Or shrink. Based on the principle of lever, the switch can be turned on and off to achieve the purpose of constant temperature. The liquid-expandable thermostat has the performance characteristics of accurate temperature control, stability and reliability, small temperature difference between on and off, large temperature control adjustment range, and large overload current. Liquid expansion thermostats are mainly used in temperature control occasions such as household appliances industry, electric heating equipment, refrigeration industry and so on.

Pressure thermostat

The thermostat converts the change of the controlled temperature into a change of the space pressure or volume through a closed temperature bulb and capillary filled with a temperature-sensitive working fluid. When the temperature setting value is reached, through the elastic element and the fast transient mechanism, The contacts are automatically closed to achieve the purpose of automatic temperature control. It is composed of a temperature sensing part, a temperature setting main body, a micro switch or an automatic damper for opening and closing. Pressure thermostats are suitable for refrigeration appliances (such as refrigerators and freezers, etc.) and heaters.

Electronic thermostat

The electronic temperature controller (resistance type) is measured by resistance temperature sensing method. Generally, platinum wire, copper wire, tungsten wire and thermistor are used as temperature measuring resistors. Each of these resistors has its own advantages. General household air conditioners mostly use thermistor type. Electronic temperature controllers have the advantages of stability and small size, and are used in more and more fields.

Digital thermostat

Digital electronic temperature controller is an accurate temperature detection controller,

Thermostat (Picture 8)

The temperature can be digitally controlled. Thermostats generally use NTC thermal sensors or thermocouples as temperature detection elements. Its principle is: the NTC thermal sensors or thermocouples are designed into the corresponding circuits. The NTC thermal sensors or thermocouples change with the temperature. Corresponding voltage and current changes will be generated, and then the changed voltage and current will be detected and quantified by the microcontroller, and corresponding control will be done. The digital temperature controller has the characteristics of high accuracy, good sensitivity, intuitiveness and convenient operation.

main effect

In most cases in Europe, the thermostat is a necessary accessory for the wall-hung boiler, and the two are delivered to the user at the same time, and most of the thermostats equipped are smart thermostats. In China, nearly 95% of wall-hung boilers that have been installed in operation and are being installed and debugged and are ready to be put into use are not equipped with any form of simple or intelligent thermostat in advance. The room heating system equipped with thermostats, especially smart thermostats, is an extremely prominent and most important link in the comprehensive energy-saving heating system.

Convenience: Automatically adjust the wall-hung boiler in advance or delay every day, eliminating manual operation, which is most necessary for office workers’ families;

Comfortable: The room temperature is automatically adjusted at each time of day, morning, night and night, eliminating the embarrassment of getting up in the morning and waiting for the room to heat up after returning home from get off work.

Gas-saving: the extensive water temperature control is changed to advanced and accurate room temperature control, and the room temperature is set at different intervals to run on demand, without the need for open day and night gas heating;

Don’t worry: when the room temperature is too low, the wall-hung boiler is forced to start, and the room can be safely protected against freezing with very little gas.

Service life

Thermostats are widely used in various home appliances, such as refrigerators, water dispensers, water heaters, coffee makers, etc. The quality of the thermostat directly affects the safety, performance and life of the whole machine, and is a very critical component. Among the many technical indicators of thermostats, life is one of the most important technical indicators to measure thermostat products. The home appliance standard stipulates that the life of the thermostat is at least 10,000 times. Some home appliances, such as the thermostat that controls the motor-compressor in refrigerator products, and some thermostats in the liquid-filled radiator require at least 100,000 times.

There is often an indicator light on a key switch of household lighting. The resistance of this kind of indicator light is extremely large, so that the current in the circuit is extremely small, so that the voltage of the electric appliance cannot reach the rated voltage at night and cannot light up. Generally, there is a capacitor in this kind of indicator light because of a small The indicator light can not tolerate 220v voltage.

basic concepts

A device that uses lights to monitor the working or position status of circuits and electrical equipment. The indicator light is usually used to reflect the working state of the circuit (powered or not), the working state of the electrical equipment (running, out of service, or test) and position state (closed or open), etc.

The indicator light using incandescent lamp as the light source is composed of lamp cap, bulb, lampshade and connecting wire, etc. There are also light-emitting diodes as indicator light, which are generally installed on the panels of high and low voltage power distribution devices, panels, tables and cabinets. On the panel of some low-voltage electrical equipment, instruments or other conspicuous locations. The indicator light that reflects the working status of the equipment, usually a red light is on to indicate that it is in operation, a green light is on to indicate that it is in a state of shutdown, and a milky white light is on to indicate that it is in a test state; Off means that the equipment is de-energized; the indicator light that reflects the working status of the circuit, usually a red light on means live, and a green light on means no electricity. In order to avoid misjudgment, check the condition of the bulb or light-emitting diode frequently or regularly during operation.

The rated working voltage of the indicator lamp is 220, 110, 48, 36, 24, 12, 6, 3 V and so on. Limited by the current through the control circuit, and in order to prolong the service life of the bulb, it is often adopted to add a current-limiting resistor in front of the bulb or use two bulbs in series to reduce the operating voltage.

Introduction

Installed on the dashboard in the cab, the number depends on the design. It is used to indicate related lighting, light signals, and the technical status of the working system, and to send out warning light signals for abnormal conditions.

As shown in the figure, there is often an indicator light on a key switch of a household lighting lamp. In actual use, it is found that when the switch is closed, only the lighting lamp emits light; when the switch is disconnected, the lighting lamp is off, and the indicator light will emit a faint light to display the position of the switch at night. According to the control characteristics of this key switch, the connection mode of the lighting lamp (A) and the indicator lamp (B) can be correctly indicated.

Car indicator light

Engine fault indicator

The engine failure indicator is represented by CHECK ENGINE or MIL. It has two states and indications. One is always on, indicating that the engine electronic control system has malfunctioned; the other is flashing, indicating that the malfunction is still affecting the engine. Performance (such as exhaust emissions, etc.)

Replace lubricating oil indicator

The oil change indicator is indicated by “CHANGE OIL'”. For example, the “CHANGE OIL'” lamp on the dashboard of a Buick station wagon is on to remind the driver that “the oil should be changed”. After changing the oil, the indicator light should be “zeroed”.

Temperature warning light

Exhaust temperature, warning light Modern cars have a three-way catalytic converter, so the exhaust temperature has increased, but too high exhaust temperature can easily cause damage to the three-way catalytic converter, so this type of car is also equipped with exhaust Temperature warning device. When the exhaust temperature warning light is on, the driver should immediately reduce the speed or stop. When the exhaust temperature drops, the warning light will automatically go out (but after the fuse exhaust temperature warning light is on, if it doesn’t If the exhaust temperature warning light does not go out, you should find out the cause and eliminate the fault before continuing to drive.

Brake warning light

The brake warning light is red, and the pattern is a “!” symbol inside the circle. If the red brake warning light is on, it means one of the following conditions exists in the brake system:

(1) The friction plate of the brake is severely worn;

(2) The brake fluid level is too low;

(3) The parking brake has been tightened (the parking brake switch is closed);

(4) Under normal circumstances, if the red brake warning light is on, the ABS warning light will light up at the same time, because the ABS system cannot play its due role even if the conventional brake system fails.

Seat belt not fastened warning light

The seat belt is not fastened warning light is indicated by a graphic (a seat belt diagonally across the occupant’s chest). After the ignition switch is turned on (ON), if the driver is not wearing a seat belt, the warning light will light up to remind the driver People fasten their seat belts. If the seat belt is not fastened and the warning light does not light up under any circumstances, check whether the fuse of the light is blown, whether the bulb is burned out, and whether the line voltage meets the regulations.

Hazard warning lights

Hazard warning lights are used to warn other vehicles and pedestrians when the car has a major failure or emergency. The hazard warning signal is represented by the front, rear, left and right turn signals flashing at the same time.

The hazard warning light is controlled by an independent switch, and generally shares a flasher with the turn signal light. When the hazard warning light switch is turned on, the turn signal circuits on both sides are turned on at the same time, and the front, rear, left and right turn signals and the left and right turn indicators on the dashboard flash simultaneously. Since the hazard warning light switch connects the flasher to the battery, the hazard warning signal can also be used when the ignition switch is turned off (OFF) and parking.

effect

1. Oil indicator

The function of the indicator light is to display the oil pressure condition in the engine. When the key door is opened, the indicator light is on when the vehicle self-checks, and it goes out after starting. According to the Gangcheng Driving School, the indicator light is always on, indicating that the engine oil pressure of the car is below the prescribed standard and needs maintenance.

2. Water temperature indicator

The water temperature indicator lamp mainly displays the temperature of the coolant in the engine. It only lights up for a few seconds during the vehicle self-check, and is usually off. Usually we hear a lot of so-called engine “boiling”, which means that the temperature of the coolant exceeds the specified value, and the driving should be suspended immediately for maintenance.

3. Handbrake indicator

The easiest mistake made by novices is that the handbrake is turned on but not released. The indicator is a circle! Or the letter P, it is usually off. When the handbrake is pulled up, the indicator light automatically lights up. At present, only some models have a warning sound that the handbrake is not used when driving.

4. Battery indicator

The battery life of a new car is at least two years, but if it is a used car or a stock car, you need to pay attention to this indicator in advance. This light is also on during vehicle self-checking and goes out after starting. If the indicator light is always on after startup, it means the battery needs to be replaced.

5. ABS indicator

The ABS light does not flash when the engine is turned on or does not go out after starting, indicating that the ABS is malfunctioning.

6. Seat belt indicator

The indicator light showing the status of the seat belt, depending on the model, the light will be on for a few seconds to give a reminder, or it will not go out until the seat belt is fastened, and some cars will also have a sound prompt.

7. Engine working status indicator

It lights up after switching on the switch, and goes out after about 3-4 seconds, and the engine is normal. If it is not on or keeps on, it means that the engine is faulty and needs to be overhauled in time.

8. Brake indicator

The function of this car indicator is to show the brake disc wear and the status of the brake system. If it is always on, the brake system should be checked immediately.

9. Refuel indicator

Seeing this light is on, it means that the amount of fuel in the fuel tank is low, and it is best to enter the gas station immediately.

10. Airbag indicator

The airbag indicator light is an indicator light that shows the working status of the airbag. It lights up when the switch is turned on and goes out after about 3-4 seconds, indicating that the system is normal. If it is not on or constant, it indicates that the system is faulty.

The button switch refers to a switch that uses a button to push the transmission mechanism, presses or disconnects the moving contact and the static contact, and realizes the circuit switching. Push button switch is a kind of master electrical appliance with a simple structure and very wide application. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

Basic Introduction

Button switch, also known as the control button (button for short), is a low-voltage electrical appliance that can be manually and generally reset automatically. Buttons are usually used in circuits to issue start or stop instructions to control the on and off of electrical coil currents such as electromagnetic starters, contactors, and relays.

A button switch is an electrical appliance that is used to switch on and off small current circuits that are pressed to act, and released to reset. Generally used in control circuits with AC and DC voltages below 440V and currents less than 5A. Generally, the main circuit is not directly manipulated, and it can also be used in interconnecting circuits.

In actual use, in order to prevent misoperation, buttons are usually marked or painted in different colors to distinguish them. The colors are red, yellow, blue, white, black, green, etc. Generally, red means “stop” or “dangerous” operation; green means “start” or “on”. The emergency stop button must be a red mushroom button. The button must have a metal protective retaining ring, and the retaining ring should be higher than the button cap to prevent the accidental operation of the button. The material of the button board and button box where the button is installed must be metal and connected to the main ground bus of the machine.

Structure Principle

There are many types of button switches, which can be divided into common snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, indicator type, illuminated symbol type and key type, etc., including single button, double Button, I button and different combinations. Generally, it adopts a water accumulation structure, which is composed of a button cap, a return spring, a static contact, a moving contact, and a shell. It is usually made into a composite type. There are a pair of normally closed contacts and normally open contacts. Some products can pass The series connection of multiple elements increases the number of contact pairs. There is also a self-holding button, which automatically maintains the closed position after being pressed, and can only be opened after power failure.

When the button is not pressed, the moving contact is connected to the static contact above, and this pair of contacts is called a normally closed contact.

How to choose your push button switch

(1) According to the different use occasions and specific purposes: select the type of button according to the use occasion, such as open type, protective type, waterproof type, anti-corrosion type, etc.; select the appropriate form according to the use, such as handle rotary type, key Type, emergency type, illuminated type, etc. For example, the general button on the panel of the console cabinet can be opened first; if you need to display the working status, use the indicator type; in very important places, in order to prevent unrelated personnel from misoperation, the key type should be selected; when there is corrosive gas Use the anti-corrosion type.

(2) Select the color of buttons and indicator lights according to the requirements of working status, instructions and working conditions: green for “start” or “power on”, and red for “stop”. In addition, the voltage of the indicator light (bulb) is divided into 6.3V, 12V, 24V, etc.

(3) Determine the number of different buttons according to the needs of the control loop: such as a single button, double button, three-button, multi-button, etc. For example, when three kinds of controls of “forward”, “reverse” and “stop” are required, three buttons can be used and installed in the same button box; when only “start” and “stop” control are required, two buttons are used to assemble them Inside the same button box.

Use and maintenance

(1) Check the button frequently to remove the dirt on it. Due to the small contact distance of the button, after years of use or when the seal is not good, the inflow of dust or oil in various stages of emulsion will cause the insulation to decrease or even a short circuit accident. In this case, insulation and cleaning must be done, and corresponding sealing measures must be taken.

(2) When the button is used in a high-temperature environment, it is easy to deform and age the plastic, causing the button to loosen, causing a short circuit between the terminal screws. According to the situation, a fastening ring can be added to tighten it during installation, or an insulating plastic tube can be added to the connection screw to prevent loosening.

(3) For the button with indicator light, the bulb will be heated, and the plastic lamp cover will be deformed for a long time, which will make it difficult to replace the bulb. Therefore, it is not suitable to be used in places where the power-on time is long; if you want to use it, you can appropriately lower the bulb voltage to extend its life.

(4) If poor contact is found, the reason should be found out: if the contact surface is damaged, it can be repaired with a fine file; if the contact surface has dirt or soot, it is advisable to wipe it with a clean cotton cloth dipped in a solvent if it is a contact spring. If it fails, it should be replaced. If the contact is severely burned, the product should be replaced.
