Abstract
The disclosure involves a lock and control assembly which can be either manually operated after insertion of a key in a lock cylinder or electrically energized by a switch from a remote location so that it can be thereafter manually manipulated without insertion of the key in the lock cylinder. The lock and control assembly also includes a mechanical override means to enable it to be actuated to its locked position, but not its unlocked position, in the event of an electrical power failure or a failure in the energizable means.
