ABSTRACT:
A switched receptacle includes a latching relay selectively providing power to an outlet receptacle. The latching relay is controlled to insure that a flux density in the set mode is no greater than that which is needed to actuate the latching relay while allowing the latch to remain in the actuated position even if this power is terminated. Current limiting is provided for resetting so that zero flux density results when unlatching.
