ABSTRACT:
A power interlock switch for an appliance having a removable panel, the power interlock switch comprising a base mounted to the housing, first and second switch terminals mounted to the base, a leaf spring conductor mounted to the first switch terminal and deflectable into contact with the second switch terminal, and a pivotally mounted lever which is engaged by the removable panel and rotates to deflect the leaf spring conductor into bridging contact across the two switch terminals. One conductor of the appliance line cord is connected to one of the switch terminals via a clip and tab structure, and the other switch terminal is connected to electrical components of the appliance. A third terminal mounted to the base has tabs for connecting the other conductor of the line cord and an additional conductor completing the circuit. A cover is provided and clamps the line cord to the base for strain relief purposes. When the removable panel is removed from the appliance, the leaf spring conductor separates from contact with the second switch terminal to cut off power to the electrical components of the appliance.
