PURPOSE:To improve both safety and reliability of a remote control device by providing plural remote control switches corresponding to a load and setting a switchable reception inhibition switch to a common circuit of those control switches. CONSTITUTION:A control signal is transmitted to an indoor power line 1 from a control device 2 connected to the line 1 and received by a receiver 3 out of plural receivers. Thus a device of a load 4 is turned on and off. The device 2 contains desired numbers of switches 5 corresponding to the load. These switches 5 are connected to a microcomputer 7 via a reception inhibitation switch 6 connected to a common circuit of these switches. The ON/OFF signal of the computer 7 is transmitted to the line 1 via a transmitter 8. |
