To provide a radio-wave controlling remote control multi-tap capable of opening and closing an electric circuit by means of a remote control device, even if a power supply source is set at a concealed place or in a remote place in terms of a position or even if an obstacle is placed, while the power supply device has become versatile accompanied by the spread of OA equipment.

The radio-wave controlling remote controller is recommended to use, since an infrared remote controller is difficult to control when an obstacle is placed. The radio-wave controlling remote controller with a single frequency, however, exerts an adverse effect on the other equipment. To avoid this, a personal identification number stored in an I. C. is accompanied to each control unit to prevent the radio-wave controlling remote controller from acting independently and malfunctioning.
