Abstract
983,303. Electrically - released switches. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. June 20, 1962 [June 27, 1961], No. 23222/61. Heading H2B. A relay which is retained set, after electromagnetic actuation, by permanent magnetism comprises a core 1, an armature 8 at one end of the core, a permanent magnet 5 at the other end, a yoke 7 extending from said other end, a magnetic member 6 between the core and permanent magnet which is spaced from the yoke to provide an air-gap 9; the arrangement being such that in the energized position the reluctance to the flux of the permanent magnet of a first magnetic circuit comprising the core, the armature and the yoke is less than the reluctance of a second magnetic circuit comprising the magnetic member, the air-gap and the yoke, but in the de-energized position the reluctance of the first circuit is greater than the second. The armature is biased by a spring to the open position and may be operated either by two opposed windings 2, 3 or by a single winding.
