Abstract

941,653. Electromagnetic relays. WESTERN ELECTRIC CO. Inc. April 22, 1960 [Oct. 22, 1959], No. 14195/60. Heading H2B. A magnetically controlled relay has one contact element formed of a material having a plurality of stable magnetic states. In Fig. 1 when a coil 6 is momentarily energized the remanent state of the element 3 is changed so that it is then attracted to or repelled from the other reed contact 4 which is magnetized by a permanent magnet 5. The reed 4 may be made of the same material as the reed 3, but permanently magnetized with or without the magnet 5 to prevent loss of magnetism. In Fig. 2 (not shown), both reeds are of the remanent magnetic material and a coil is provided for each reed. In Fig. 3 (not shown), a construction requiring energization of two coils as described in Specification 941,654 is shown. Specification 870,906 also is referred to.
