Wire Spring Relay

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.

Famous quotes containing the words wire and/or spring:

    A new idea is rarely born like Venus attended by graces
    More commonly it’s modeled of baling wire and acne.
    More commonly it wheezes and tips over.
    Marge Piercy (b. 1936)

    My ideas are a curse.
    They spring from a radical discontent
    with the awful order of things.
    I play clown. I play carpenter. I play nurse.
    I play witch.
    Anne Sexton (1928–1974)
