ABSTRACT:
An electrical circuit that includes a ferrous plunger operated by electrical coils and pulses current. One end of the plunger extends and retracts into contact with an adjustable latch such that only one moving part is required and only a small amount of electrical energy. Selectively activating the coils throws the plunger between the locked and unlocked positions. The circuit includes provisions to open the lock in the event of power failure. The plunger mechanism is mounted on an easily installed housing that, with the latch mechanism, has hardware for accurate alignment and installation. In one embodiment, a series of plungers can be operated by a wireless remote-control device. In another embodiment, the series of plungers can be operated by a switch mounted on a wall. In yet another embodiment, the series of plungers can be operated only after entering a four digit code into a programable key pad unit.
