Abstract
An electrically powered, fast acting transfer switch utilizes a single action solenoid that, alternately, through a mechanical assembly, moves the handle of one electric power switch between OFF and ON positions. A coupling including a rigid strap operates the handle of a second electric power switch oppositely between ON and OFF positions. The mechanical assembly includes an electromagnet drive plate to which the electromagnet of the solenoid is secured and an armature drive plate carrying the solenoid armature. A latch mechanism alternately holds one drive plate and then the other stationary so that the electromagnet and armature alternately move to effect reciprocal movement of the handle of the one electric power switch, and through the rigid strap, the handle of the second electric power switch.
