Abstract
A locking latch for an appliance provides an improved three-wire interface that reduces the chance of malfunction if the door is forcibly opened when it is in the lock state and a bi-stabile actuator is used. In one embodiment, the door switch is positioned to disengage the major load of the washing machine when the doors open, regardless of the lock or unlock state.
