ABSTRACT:
The invention adapts to an electronic lock comprising a housing, and a plug supported for rotation within the housing and having a keyway to receive the blade of a key which rotates the plug during operation of the locking apparatus. A locking member is movable into engagement with the plug to prevent the movement of the plug and the operation of the locking apparatus and movable out of engagement with the plug to allow the rotation of the plug and the operation of the locking apparatus. A solenoid having a core coupled to the locking member moves the locking member into and out of engagement with the plug. A permanent magnet is movable between a first position to receive and hold the solenoid core to maintain the locking member out of engagement with the plug, and a second position to release the solenoid core, and a driving means moves the magnet in at least one direction between the first and second positions. Consequently, power may be turned off to the solenoid after retention by the magnet and a battery source is preserved.
