Abstract

PURPOSE:To greatly simplify wiring to electric appliances located away from their switches, by making it possible to separately operate the appliances even if they are connected to the switches through a single intermediate signal line. CONSTITUTION:A transmitter 3, the signal line 4, a receiver 5, a battery 6 and a power line 7 are connected between lamps 1 located on the rear of a truck and the switches 2 corresponding to the lamps and located in front of the driver's seat. The transmitter 3 comprises a non-stable oscillator 31, differentiation circuits 32-0-6 connected in series with the oscillator 31, and monostable circuits 34-1-6 whose constants are determined depending on the turn-on/off of the corresponding switches 2-1-6. A number of pulse signals corresponding to that of the switches are transmitted through the signal line 4 by turning on or off the switches in succession to a periodical reference pulse signal. The receiver 5 functions to discriminate the pulse signals.
