Abstract

941,671. Switching systems; electromagnetic relays. CLIFFORD & SNELL Ltd. May 7, 1962 [May 8, 1961], No. 16595/61. Headings H2B and H2H. [Also in Division H1] A system comprising two relays, one having an operating coil 5, and an additional coil 8 magnetically coupled thereto, together with pairs of contacts 7 and the other relay having contacts 10 and an operating coil 9 connected with the additional coil 8 of the first relay has both relays mounted on a base 3 and housed in a transparent cover 4. Thus energization or de-energization of the first mentioned relay will cause momentary operation of the contacts of the second relay. If it is desired to avoid the operation of the second relay when the first relay is either energized or de-energized, a suitably poled half wave rectifier 11 may be connected across the additional winding 8.
