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. Par conséquent, the micro switch used in the door needs to have a waterproof function and have the characteristics of a long life.

The automotive door switches are detection switches. Many people mistakenly think the door lock is a micro switch, which is incorrect. The micro switch is an electronic switch that detects whether the car door lock is closed.

If the automotive door lock switch is broken, there will be some severe consequences:

1. If the door is not closed, there will be no alarm.
2. The most serious one is this one, the anti-theft function is invalid. If someone opens this door illegally, no alarm will be issued!
3. After removing the key and getting off the car, there will be no alarm sound if the headlights or turn signals are not turned off.
4. After opening the door remotely, pull the door. If you put the key on the car when you come out and close the door, the door will be automatically locked at this time, and the anti-theft function will be turned on, which is very inconvenient for us to travel.
5. The oil pump has no preparatory work and isn’t easy to start!

Common faults and troubleshooting of car door locks are:

1. Don’t lock the auto door;
2. Don’t unlock the auto;
3. The locking function is invalid;
4. The door lock has a large opening force;
5. Large opening stroke of the door lock;
6. Analysis of the cause of collision lock.

Don’t lock the auto door.

The common reason is that the internal and external opening structure pre-tensions the lock block, which makes the lock bolt and block unable to engage normally, and the door lock cannot be locked.

A cette époque, the related size of the internal and external opening mechanism can be lengthened to eliminate the fault.

Don’t unlock the auto.

This situation is the opposite of the inability to lock normally. The common reason is that the connection size is large, Only making it smaller to solve the problem.

This problem will also occur when the lock block’s engagement is significant. In this case, change the arrangement.

When the micro switch of the door lock is broken, how do we replace it?

There are two solutions, one is to find a 4S shop for repair and replacement, and the other is to change the micro switch by yourself manually. If you buy a micro switch yourself, you must purchase one with a waterproof IP67 function, pick the suitable micro switch, and pay attention to the rating, taille, tension, etc.
