What is a unionwell micro switch for car door locks?

The car door micro switch usually refers to the microswitch installed on the car door. It is a kind of door-lock switch used to sense or detect whether the car door, child lock, and central control are locked in place. Its working principle is to respond when the car door is closed. The micro switch’s mechanical parts will touch the micro switch’s operating handle.

When people press the operating handle, the action will turn on the circuit, and then a message will be transmitted to the instrument for display.

If the auto door is not closed correctly, it must be pressed due to the structure design calculation. Under the stroke, the circuit of the micro switch will be turned off, and the message displayed on the instrument will show a warning prompt that the door has not been closed.

Due to the frequent opening and closing of the door, it is inevitable to get wet when traveling on rainy days. Ji ber vê yekê, the micro switch used in the door needs to have a waterproof function and have the characteristics of a long life.
