Abstract
The invention relates to an electric circuit suitable for cutting off an electric power supply of an electrical device, said electric circuit receiving as input at least two discrete electrical signals, the values of which condition the power supply of the electrical device, the discrete electrical signals having a high state if the electrical device needs to be supplied: the electric circuit including a voltage source; a first cut-off unit connected between the electrical device and the voltage source, the first cut-off unit having an open or closed state in accordance with the discrete electrical signals; a second cut-off unit connected to the intersection between the electrical device and the first cut-off unit, and to an earth line, the second cut-off unit having a state that complements the first cut-off unit if the discrete electrical signals are in identical states, said first and second cut-off units being controlled such as to generate a short-circuit in the event of a divergence between the discrete electrical signals.
