<p>Remote-control device with carrier current intended to be mounted in a electrical network comprising an electrical load (3) and an electrical generator (1) engendering an electrical parameter, voltage or current, at its terminals. This device comprises on the one hand an emitter (10) including an impedance (4') and a switch (5') which are electrically connected so that the switching of the switch (5') makes the fixed parameter vary across the terminals of the electrical load (3), and on the other hand a receiver (9) including an impedance (4) and a switch (5) which are electrically connected so that the switching of the switch (5) does not make the fixed parameter vary across the terminals of the electrical generator (1). <IMAGE></p> |
