APPLIANCE DOOR-LOCKING APPARATUS ABSTRACT OF THE DISCLOSURE: Safety-locking apparatus for an appliance door latching mechanism includes a solenoid operated locking member requiring an independent manual operation to un- lock the latching mechanism in order to move the latch from the unlatched to the latched position and vice versa. A high-current switch is included operable by an actuating member responsive to operation of the door latching mech- anism such that an appliance, such as a pyrolytic type of self-cleaning oven, may not be operable in the heat cleaning process unless and until the door latching mechanism, and thereby the door, are in the latched and locked-closed position. A cam surface on the switch actuating member serves to operate the high-current switch and also pro- vides mechanical advantage for the forced breaking of the switch contacts should they become welded together.
