Abstract

A switching device, a switching module and a control module configured to command the interruption of a current by way of the switching module in the event of a fault. The switching module includes a circuit carrying the current and including, in series, two back-to-back depletion-mode JFETs and a switching component that switches between two configurations. The switching component allows the current to flow in one configuration and prevents the current from flowing in the other configuration, which it is in by default. The control module generates a first signal for keeping the switching component in the first configuration, the control module being configured, in the event of a fault, to generate a second signal for commanding the interruption of the current by way of a transistor, and configured to interrupt the first signal in the event of a fault.
