Wire Spring Relay
A wire spring relay is a type of relay, primarily manufactured by the Western Electric Company for use by the Bell System in electromechanical telephone exchanges. It was licensed for use around the world, and was commonplace in Japan. A wire-spring relay has springs made from drawn wires of phosphor bronze, rather than cut from flat sheet metal as in the earlier flat spring relay, and has greater reliability than other types of relays. Wire spring relays were the most suitable relays for logic and computing functions. They were used extensively in markers, which were special purpose computers used to route calls in crossbar switch central offices.
