Abstract
891,192. Sequential switching systems. WARHURST, F. March 2, 1960 [March 2, 1959], No. 7167/59. Class 38 (4). A control system for switching at determined times one or more domestic appliances supplied from permanent socket outlets adjacent to the appliance comprises a timer control unit having a series of motor-driven timing cam-operated switches A-F, control switches K1 K2, one to each appliance, a switch unit, and a load socket unit adjacent to the appliance, the socket unit having a low voltage relay R controlling the appliance through contacts R2, R3. On a cam switch, say A being closed, a supply from a rectifier 10 extends through bus-bar A and a plug P1 to energize the relay winding W1 through normally closed switches K1 K3, which relay is held through self-holding winding W2 and contact R1. The circuit may be broken through other cam-operated switches S1 or Z or manually by switches K1 K3. A jack is provided on each load socket unit for the insertion of a warning buzzer, or a telephone set which can be connected via contacts on corresponding switches K2 to a similar handset in another room. The appliances and/or socket units may be connected directly to permanent wiring instead of through plugs and sockets.
