2 Step Push Button Switch Product Introduction
This 2 step push button switch has a knob, also called a knob switch. The mounting hole is 22 mm. We can make 1NO1NC or 2NO2NC.1NO1NC is a 3-pin model, and 2NO2NC is a 6-pin model.
This material uses gold-plated terminals, and the internal uses all-silver contacts, the wiring is stable and smooth, and the conductivity is stronger.2 The step push button switch can reach 5A, the waterproof grade is IP65, and the shell material is stainless steel.
What is the rotation 2 step push button switch?
A rotating 2 step push button switch can be used to replace the rotary pulse generator that mimics the function of traditional resistance potentiometers. These rotating 2 step push button switches are generally used in the front panel of the instrument and the man-machine interface of the audio-visual control panel. The rotary buttons are orthogonal. Optical encoders are used as pure digital devices instead of imitating potentiometers. These rotary 2 step push button switches are similar in appearance to traditional or resistive potentiometers, but the internal structure of these rotary buttons is completely digital and uses optical skills. Similar to traditional incremental encoder products, there are two quadrature output signals (channel A and channel B), which can be directly connected to the encoder processing chip.

Rotate 2 step push button switch is a button that rotates the handle to control the main contacts on and off. There are also two structural forms of the rotary button, which are a single-pole unit structure and a multi-pole multi-position structure. Single-pole unit rotation 2 step push button switch is often used together with rotary potentiometers in applications, and multi-pole multi-position rotary buttons are mostly used to switch the operating state circuit.
Waterproof metal 2 step push button switch can be used in some humid environments that need to be waterproof, with excellent waterproof performance, so there are many types of waterproof metal 2 step push button switches on the market, how do we judge waterproof metal 2 step push button switch The sealing performance?Is the certification complete?
Relevant regulations, SGS certification; and have VDE/DEMKO/KEMA (currently using EU ENEC), UL/CSA, and other certifications. These are the certification requirements for high-quality waterproof 2 step push button switch.
IP waterproof standard
The main evaluation standard for the waterproof performance of the waterproof switch is based on the IP waterproof grade standard. To see the waterproof performance of the waterproof switch, it mainly depends on the two digits XX at the back of IPXX. The first X is from 0 to 6, and the higher level is 6; the second X is from 0 to 8, and the higher level is 8; therefore The higher waterproof grade of the waterproof button switch is IP68.
The waterproof button switch has a reasonable design, long service life, high temperature resistance and high current impact resistance.
Metal 2 step push button switch is a kind of master electrical appliance that is widely used. Sometimes when the metal button switch is damaged due to improper use or long-term use, we need to disassemble and repair it. How should the metal button switch be disassembled?
First, open the cover of the wall switch. Generally, we can see an opening of about 0.5 cm under the cover. We can start to open the cover from here. After opening the cover, we still cannot see the fixing bolts. We need to remove the switch panel, and then use a small screwdriver to carefully pry the switch panel to the front so that the switch panel itself will fall. See the two fixing bolts on the mounting frame, use a Phillips screwdriver to turn counterclockwise to remove the entire wall switch. After taking it out, replace it with a new wall switch according to the original wiring method. Normally, the L terminal is connected to the incoming line, and L1 or L2 is connected to the light line. When the switch is disassembled, first remove the outer waterproof cover. We can see a small gap on the side of the waterproof cover. Use a small flat-blade screwdriver to insert it and knock it hard to remove the waterproof cover. After the mask is removed, you can see that there are screws on both sides. Unscrew the screw switch and it will open naturally. After opening the switch panel, we need to replace it with a new one. Remove the wires from the old switch panel and re-fix it to the corresponding place of the new switch panel.
The above is about how to disassemble the metal button switch. I hope it will be helpful to everyone. If you find that the contact is poor, you should find out the reason: if the contact surface is damaged, you can use a fine file to repair it; if the contact surface has dust or soot, It is advisable to wipe clean with a clean cotton cloth dipped in a solvent; if the contact spring fails, it should be replaced; if the contact is severely burned, the product should be replaced.
