ABSTRACT:
A door interlock system for use with a microwave oven. The interlock system includes a slider member movably mounted to the cabinet of the oven for movement between released and interlocking positions. A catch structure is provided to be movable with the slider member and an interlock structure is provided for selectively securing the door in closed position across the cabinet opening by cooperation with the catch structure. The interlock structure may include fixed latching members on the door and a movable operator on the door arranged to move the slider member between the released and interlocking positions. Actuator structure is provided to be operated concurrently with the latching of the door to operate switches associated with the microwave energy generating device to permit operation of the generating device only when the door is latched in the closed position.
