Marine Rocker Switch Product Introduction


This marine rocker switch is a switch with a waterproof surface. A waterproof leather case is added to the original base, which makes it waterproof. Compared with the old waterproof cap, the waterproof leather case is more convenient to use and more beautiful.

Generally, we will pad print ‘ 0 ‘ , ‘ I ‘ on the marine rocker switch.
The ‘ I ‘ position represents the number ‘ I ‘, which means on, which is equivalent to the level signal on.The ‘ 0 ‘ position means the number ‘ 0 ‘, which means off, which is equivalent to the level signal off.

‘ I ‘ and ‘ 0 ‘ are generally marked on the two ends of the button of the ship type (rocker) switch. A more scientific design is to mark the word ‘ON’ on the ‘ I ‘ end of the switch installation position, and mark ‘OFF’ on the ‘ 0 ‘ end.

How to wire the marine rocker switch with lights on three legs?

The wiring method of the three-pin switch is shown in the figure, the middle pin is the com point, and the two sides: one is the NC (normally closed) point and the other is the NO (normally open) point.

The lamp is connected between pin 1 and pin 3. There are two ways of connection. One is to connect pin 2 and pin 3 together, so that when the switch is closed, the lamp is short-circuited and does not light up. When the switch is open, the lamp is connected. It lights up on the electrical appliances and the live wire to indicate that the switch is off.

Another connection method is to use a separate neutral wire to connect to pin 3, so that the light is on when the switch is closed, and it does not light when the switch is open, which acts as an indicator of electricity consumption.

Waterproof marine rocker switch water-proof performance judgment standard waterproof marine rocker switch is very popular in daily life. In many households, toilets and kitchens and other humid places are installed waterproof marine rocker switches. Waterproof rocker switch refers to a switch that can be operated with wet hands and can use electricity more safely.

Nowadays, there are many types of waterproof marine rocker switches on the market. Generally, mechanical operation switches refer to waterproof rocker switches. An extra waterproof cover is added to the outside of the switch to enhance safety. In the real sense, there are relatively few switches on the market that can be operated with wet hands, except for some major brands such as Siemens, which are internationally famous, and Narcoleptic of Elan tron.

Judging the performance of waterproof marine rocker switch can be judged according to three aspects.

1. Whether the certification is complete. Whether it contains ROHS, SGS, ENEC and other certifications, these are the certification requirements for high-quality waterproof rocker switches, and they are also required by the export customs.

2. The performance evaluation of the waterproof rocker switch is based on the IP waterproof grade standard. The highest waterproof grade of the current switch is IP68.

3. Some other criteria for judgment. The waterproof marine rocker switch has reasonable design, high temperature resistance, high current impact resistance, long service life and other factors that need to be considered.

The specific application of the waterproof rocker switch is also restricted by factors such as the installation method, the installation direction of the product, the airflow, and the working voltage.

For example, the waterproof marine rocker switch produced, which has a strong sealing performance, has reached the leading level, but it is still necessary to prevent the intrusion of corrosive gases or substances.

How to choose marine rocker switch?

I don’t know that the marine rocker switch has a power limit. If the heater, electric iron and other plug-ins are plugged into the same marine rocker switch, the marine rocker switch will be overloaded and heated, and the insulating material will also heat up and deteriorate, which may cause a fire. As the weather gets colder, marine rocker switch plays an important role in the lives of citizens, but if it is not selected properly, there will be safety hazards and unnecessary damage to family property and life safety. Therefore, the editor here reminds the general public to replace marine switches that do not comply with safety regulations as soon as possible to avoid safety accidents.

Pay special attention to the following six points when buying at the same time:

1. Choose a channel. When buying marine rocker switch, do not be greedy for cheap. It is recommended to buy it at a regular large chain supermarket, hypermarket or electrical appliance store, and keep the proof of purchase.

2. Recognize the brand. Pay attention to the monitoring and testing information released by the industry and commerce, quality inspection and other departments, as well as the comparative experiment results released by the consumer associations (consumer committees, consumer protection committees), and try not to choose brands that have been exposed and punished.

3. Look at the appearance. The manufacturer and product information on the qualified marine rocker switch packaging is complete, while some unqualified switches are simple in packaging and lack basic manufacturer and product information, especially the production date on the product packaging. Many inferior switch products do not. Indicate the production date on the packaging, which is usually unqualified. In addition, the shell panel of the qualified marine rocker switch is exquisitely made, the shell and the jack side have no burrs, the jack size is symmetrical and uniform, and the poor quality shell is rough in workmanship.

4. To the hole type. Do not buy the prohibited universal port marine rocker switch. Its three-phase jack and two-phase jack are combined, and there are three holes.

5. Count the bolts. Do not buy a two-core marine rocker switch with a three-pole jack on the plug-in board but only two pins on the plug that comes with the marine rocker switch itself.

6. Test the feel. It can be distinguished from the following four aspects: weigh the weight, repeatedly press the switch, try the plugging force, and pull the power cord.

(1) Weight: The marine rocker switch conforming to the national standard uses a lot of copper wires, thick copper sheets, and tight plastic shell, so the weight is heavier. If a substandard switch cut corners, the material will obviously be much lighter.

(2) Press the switch repeatedly: you can press it several times, the qualified products can be opened and closed freely, the sound is clear; the unqualified products will feel dull and easy to get stuck.

(3) Trial insertion and extraction force: A qualified marine rocker switch not only has a moderate and flexible feel for insertion and extraction of each hole, but also has the same insertion and extraction feel for each jack; the insertion and extraction force is too loose or too tight, poor elasticity and easy to loosen , The feel of each hole will be different.

(4) Pull the power cord: The power cord of the qualified marine rocker switch feels moderately soft and hard, and the connection with the marine rocker switch is solid and reliable. Unqualified power cords will feel soft, weakly connected, and easy to pull off.
