ABSTRACT:
A microwave oven includes a cooking chamber closed by a door. The magnetron is operated by a control mechanism which includes a circuit board and safety switches which permit the magnetron to be operated only when the door is closed. The opening and closing of the door causes a switch-actuating mechanism to be operated for turning the safety switches on or off. The safety switches, together with a lamp for illuminating the cooking chamber, are mounted on the circuit board. The circuit board is arranged horizontally, with the switches and lamp being mounted on a bottom surface thereof.
