Door Lock Circuits
This is a power switched or positive pulse door lock circuit. It contains two relays. There are different types of relays that can be placed in different configurations. They’re electronically controlled switches that allow manufacturers to use low current to control high current devices. By using relays, manufacturers can use light weight thin gauge wiring for the door switches to control the high current door actuator motors. These switches and thinner gauged wiring send a low amperage signal to the lock or unlock relay according to the switches position. The relay then completes the high amperage circuit leading to the door lock actuators.
