ABSTRACT:
A lock assembly for a sliding closure has a bolt movable into and out of the path of the closure by a movable plate. A cam surface on the plate retracts the bolt from the path of the closure. A first spring moves the bolt into the path of the closure as the plate is moved by a pivoting reset lever engaging a tab on the plate. The plate is urged in the opposite direction by a second spring. A locking aperture on the plate and a solenoid with an armature engaging the aperture are provided for locking the plate in position at the limit of its travel to hold the bolt in the path of the closure. The solenoid is operated by either an inside or outside switch to release the plate and disengage the bolt. Alternatively, a plunger on the housing can be pushed to manually disengage the armature.
