Abstract

1,032,968. Switching systems. DELMATIC Ltd. May 6, 1964, No. 18904/64. Heading H2H. A circuit providing remote control of loads such as lamps 10-12 is controlled by contacts RY1-RY2, RD1-RD2 of relays RY/3, RD/2, RY/3 being bi-stable. Momentary energization of a coil RYa illuminates lamps 10, 12 and subsequent energization of relay RD/2 extinguishes lamps 10 and illuminates lamps 12. With coil RYb momentarily energized and relay RD/2 de-energized, the lamps 10 may be illuminated by a third relay RP1. Other arrangements are described in the Specification. In an alternative arrangement a contactmaking photo-cell can be employed to control the relay RD2.
