Abstract
A microwave oven includes an electric power supply shut-off mechanism for cutting off the supply of electric power when the housing is disassembled for repair while an electric power cord remains plugged into an electric outlet. A sensor in the form of a light sensitive semiconductor and/or a piezoelectric crystal senses when panels of the oven housing are removed and thereupon causes a controller to actuate a solenoid which deactivates a safety switch for cutting off the supply of electric current.
