Abstract
A device for transmitting signals to a fuse (1), comprising a magnetic circuit and three non-magnetic circuits. The magnetic circuit comprises a coil (5) for transmitting an energy signal which will be recovered by a coil (3) inside the fuse. The three non-magnetic circuits comprise infrared emitter receiver cells mounted on supports (12, 13, 14) outside the fuse, and on supports (6, 7, 8) inside the fuse. These cells respectively co-operate for emitting and receiving information carrying signals, which are thus separate from the energy signal.
