Key Switch Wiring Steps

Step 1 First determine the live wire and the neutral wire, both of which carry different voltages and currents. Step 2 Connect the live wire of the power cord to the normally closed contact of the ...

How To Wire The Key Switch?

The key switch is generally composed of a handle, a slide plate, a movable contact piece, a fixed terminal, a compression spring, a shell, etc. It controls the on and off of the movable contact and...

Wiring Mode Of DC Circuit Breaker

Wiring behind the board. The advantage of the wiring behind the board is that when maintaining the DC circuit breaker, you only need to disconnect the front-level power supply without rewiring.

Working Conditions Of DC Circuit Breakers

The ambient air temperature is not higher than +40℃ and not lower than -5℃; and the 24-hour average value does not exceed +35℃ (except for special orders).

The Difference Between Several DC Circuit Breakers

​The DC circuit breaker adopts a special arc extinguishing and current limiting system, which can quickly break the fault current of the DC power distribution system and greatly improve the level d...

Application Places Of DC Miniature Circuit Breakers

DC miniature circuit breakers are used in large-capacity and high-voltage power systems such as power plants and substations.

Points For Attention in The Scientific Use Of Circuit Breakers

​The DC circuit breaker can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc.

Working Principle Of Self-locking Button Switch

​Self-locking button switch is a common button switch. When the switch button is pressed for the first time, the switch is turned on and held, that is, self-locking.

Precautions For Button Switch Welding

​Any incorrect welding operation may cause deformation of the plastic parts of the product, poor contact of the switch, failure of the switch with lock, etc.

Deep Analysis Of The Basic Circuit Principle Of Button Switch

​The button switch is a term used in the old standard, and is referred to as a button in the new standard (GB2900·18).
