Abstract
A lid latch assembly (10) for a household washing machine is disclosed which incorporates safety features which prevent damage to the latch assembly regardless of when the drum access lid of the machine is closed. The assembly includes a solenoid (22) operated locking lever (60) pivotally mounted to a bracket (12). An elongated slot (68) in the bracket defines a first fulcrum (66) about which the locking lever pivots during latching movement. A switch arm (30) must be depressed downwardly by a latching hook (84) connected to the machine lid (80) before the locking lever is movable to the latched position. A blocking tab (58) on the switch arm prevents movement of the lever to the latched position prior to downward movement of the switch arm. The elongated slot allows the locking lever to pivot about a second fulcrum defined by the blocking tab.
