The invention relates to an apparatus containing a relay which is activated and deactivated by means of a telephone line and of a parallel output of a microcomputer. It consists of a box containing a transformer 3, a circuit for detection of telephone signals 5 which is provided with a torus 13 operating by induction. A circuit for recognising binary codes 7 makes it possible, via a control circuit 11, to open a relay 15 acting on the phase and the neutral. The apparatus according to the invention is particularly intended for remote switching of a microcomputer. <IMAGE>
