What is the use of car micro switch?

The automobile micro switch is a kind of door switch used to sense or detect whether the door, child lock and central control are locked in place. The force is applied to the movable piece through the driving part (press pin, driving rod, etc.). When the piece is displaced to the critical point, an instantaneous action is generated, so that the moving contact at the end of the movable piece and the static contact are quickly connected or disconnected. When the force on the driving part is removed, the movable piece generates reverse action force, and when the reverse stroke of the driving patch reaches the action critical point of the movable piece, the reverse action is completed instantaneously.
