ABSTRACT:
A circuit for selectively controlling bidirectional energization of a plurality of latching solenoid coils and incorporating electrical failure detection means therein. The coils are connected in a series chain and a plurality of independently actuable switching means are provided for connecting a positive voltage potential, a negative voltage potential, or no voltage potential to any of a plurality of terminals defined by the ends of the chain and the junctions between two adjacent coils of the chain. The solenoid coils are energized by a momentary current pulse, and the switching means are selectively actuated to control the direction of the energizing current through any of the coils. A voltage divider establishes voltage potentials at the ends of the chain which vary from a predetermined value during a failure mode of operation of the circuit.
