ABSTRACT:
A latch mechanism for use with an oven having a door, the latch mechanism including a base plate which pivotably supports a latch member about a pivot point. The latch member is rotatable between a latched and unlatched position and includes a drive surface offset from the pivot point. An actuator pin is supported by the base plate for rectilinear movement wherein the actuator pin has an outer end extending beyond the base plate for engaging the oven door upon closure and an inner end drivingly engaging the drive surface for rotating the latch member into a latched position against a spring bias. The base plate is a molded plastic member having a boss including snap connection means for rotatably supporting the latch member and a sleeve for slidingly supporting the actuator pin for rectilinear movement. A solenoid is mounted to the base plate and has a locking pin selectably movable between an extended position and a retracted position. When the latch member is in a latched position, movement of the locking pin into the extended position places the locking pin in interference with the rotation of the latch member such that the latch mechanism is locked into the latched position. Two switches mounted to the base plate are positioned to sense when the latch member is in a latched position or in a locked state.
