ABSTRACT:
A switch mechanism is provided for use in an appliance having a movable appliance member mounted therein for movement between a desired and an undesired position. A first switch is mounted on the appliance and is changeable from an open condition to a closed condition. A switch arm is moveably mounted to the appliance for movement from a first switch arm position permitting the first switch to be in one of its open or closed positions to a second switch arm position permitting the switch to be in the other of its open and closed conditions. The switch arm is moveable to a third switch arm position in response to movement of the moveable appliance member to its undesired position. In its third switch arm position the switch arm permits the first switch to return to its open condition.
