Automatic power supply cut-off apparatus for a microwave oven

A microwave oven comprising a housing formed by interconnected housing portions, a cooking chamber disposed in the housing, a door for opening and closing the cooking chamber, a control unit for establishing a cooking operation, an electrical cord for supplying electrical power to the oven, and a power supply cut-off means mounted on the microwave oven for automatically cutting off the supply of electric power in response to an opening up of a portion of the housing;

• the power supply cut-off means including a switch mounted on a first of the housing portions, the switch including a displaceable button movable between a power cut-off position and an energizing position, the button being biased to a power cut-off position, the first housing portion including a hole;
• the switch further including a lever mounted at one end and facing the hole, the lever including a free end movable toward and away from the button and inherently biased so that the free end thereof is out of context with the button;
• a second of the housing portions being bent to form an integral finger of one piece therewith, the finger arranged to be passed through the hole and into direct contact with the lever in response to the first and second housing portions being interconnected, for pushing the free end into pushing relationship with the button to move the button into its energizing position.
