Abstract:
1. A dual-latching solenoid system, comprising: a) a first electromagnetic yoke; b) a second electromagnetic yoke, magnetically separate from said first yoke; c) an armature, movable bidirectionally between a first latching position adjacent said first yoke and a second latching position adjacent said second yoke; d) first and second drive windings, generating flux respectively in said first yoke and said second yoke; e) interconnection between said drive windings providing three connections for coupling said drive windings to drive circuitry, said three connections including two end connections, one from said first drive winding and a second from said second drive winding, and the third connection being a center connection electrically common to the separate drive windings; and f) electronic driver apparatus including three power output terminals driving said first and second yokes via said three connections.
