What is a Door Lock Switch?

Whether located on the center console as a central locking feature, on every door, or the master switch on the front driver door, the locking switch will lock and unlock one or all doors in a vehicle when power locks are installed.

How do Door Lock Switches work?

User-controlled automotive switches operate on the same basic premise. When a switch is pressed a circuit is either closed or interrupted, which causes the electronic actuation of the connected system. For power door locks, the switch works in two directions. By pressing lock or unlock, the door lock actuator motor will move in the direction specified due to polarity change controlled by the switch. For modern vehicles, this action will be computer controlled, and the switch only sends a signal to the control module.
