Abstract
A door condition sensing apparatus for a microwave oven includes a mechanical switch and a photodetector, each of which is separately responsive to the closing of the door. A microprocessor receives signals from both the switch and the photo-detector to determine whether the door is closed. The photo-detector is actuated by a lever which is swung by the door as it closes. The lever comprises an actuator arm of a second switch connected to the microprocessor.
