Abstract
The invention relates to an electrical circuit adapted for cutting off an electrical supply to an electrical equipment, said electrical circuit receiving as input at least two discrete electrical signals xi, i=1, N, the electrical circuit comprising: —a voltage source; —a number N>1 cutoff units Ui connected together, i=1, . . . , N in series between the voltage source and the electrical equipment, and a last cutoff unit Ubeing connected to the electrical equipment, each cutoff unit Ui exhibiting an open or closed state as a function of an electrical control signal; the cutoff units Uj, j=1, N−1 upstream of the last cutoff unit Ueach being controlled by a distinct discrete electrical signal xj, j=1, . . . , N−1, the last cutoff unit being controlled as a function of the state of the cutoff units Uj, j=1, . . . , N−1 upstream and a discrete electrical signal xdifferent from that controlling the upstream cutoff units Uj, j=1, N−1.
