Abstract
A bridging contact is arranged across two fixed contacts with a pair of parallel, closely spaced conductors serving as the bridging contact carrier. The conductors each form a pair of upper and lower links joined by means of a toggle pivot pin and are refrained from movement by means of a pair of tension springs. A high current pulse in opposite direction within the parallel conductors generates electromagnetic forces which propels the conductors apart. The bridging contact carried by the parallel conductors is thereby rapidly driven out of contact relation with the fixed contacts to interrupt the circuit.
