ABSTRACT:
A combination unbalanced load and lid switch assembly for an automatic washing machine. A switch is mounted to the side wall of a box-like housing with a spring clip that has a pair of legs extending through horizontal holes in the switch. The switch housing has a diagonally extending horizontal flange with a downwardly extending pivot portion to which is pivotally mounted a lid lever. One end of the lid lever has an actuator arm which extends in aligment to a wire extension of the lid hinge that moves upwardly as the lid is being closed to push the actuator arm upwardly. A substantially vertical unbalanced load lever is pivotally connected to the opposite end of the lid lever and is pulled downwardly against a biasing spring as the lid is closed. The unbalanced load lever has an actuating finger that depresses the plunger of the switch thereby enabling the washer motor when the lid is closed. The unbalanced load lever also has a downward leg that is engagable by the tub during an out-of-balance excursion. Pivoting of the unbalanced load lever about the lid lever causes the actuating finger to slide off the switch plunger thereby disabling the motor until the lid is opened and closed.
