Abstract

963,292. Switch contacts. STANDARD TELEPHONES & CABLES Ltd. July 27, 1961, No. 27286/61. Heading H2B. A contact spring for an electromagnetic relay comprises an elongated strip of an alloy of a base metal with a precious metal (such as gold, platinum or palladium, for example) having a contact portion or portions formed at or near one end by the deposition of a layer of the said previous metal on to the strip.
