This invention relates to technique for remote control of the current supply to electric equipment. Particularly the invention is suited for electrical equipment connected to the part of the electrical power distribution network present in households, offices, and industries, wherein an operator, by means of manipulating a transmitter, which transmits a signal to a receiver situated at a distance, is able to control, by means of a regulator connected to the receiver, the current supply to the electrical equipment. A unique identity code is assigned before hand to each receiver, said identity code including a larger number of characters, and the receiver is equipped with means for secure reception of the signals transmitted from the transmitter containing such an identity code, so that the electrical equipment may be controlled without errors. |
