Abstract

1. Short-circuit element designed to be connected in parallel to the two terminals (B'1-B1) of a conductor device (6) and of the type normally open and becoming conductor when said device stops conducting electricity between said terminals, said element comprising, on the one hand, a static ON-OFF circuit provided with at least one component (TR1) connected by its electrodes to the terminals of the device and a control electrode (G1) and, on the other hand, a trigger control circuit connected to a terminal (B1) of the device and to the control electrode, characterized in that, in its application as short-circuit element meant to create a by-pass circuit for a conductor device (6) which is part of an assembly of conductor devices (6) connected in series between two supply terminals (4) and (5), it comprises - a static ON-OFF by pass circuit provided with at least one component (TR1) having two electrodes connected directly to the terminals (B'1-B1) of the device (6), - a trigger control circuit provided with at least one ZENER (Z1) diode having a triggering function and applying to the control electrode a triggering signal which renders the component (TR1) conductive when the voltage at the terminals of the device exceeds a predetermined threshold, - a circuit connected between the terminals (B'1-B1) in parallel to the ON-OFF circuit and comprising a member (VI) for protection against excess voltage.
