Abstract

Circuit de commutation (1) destiné à être connecté à une charge et à une source de tension (2), comprenant un ou plusieurs dispositifs de commutation (6, 7, n) pour mettre la charge sous tension et hors tension, un dispositif de tirage vers le bas (4) pour court-circuiter la charge, en l'isolant ainsi de la source de tension, et un contrôleur (3) pouvant fonctionner pendant que la source est isolée de la charge, pour activer au moins un des dispositifs de commutation à la fois, un courant passant dans le dispositif de commutation activé ou dans chaque dispositif de commutation activé et pouvant être mesuré pour vérifier si le dispositif de commutation activé ou chaque dispositif de commutation activé fonctionne correctement.Switching circuit (1) intended to be connected to a load and to a voltage source (2), comprising one or more switching devices (6, 7, n) for switching the load on and off, a device for pull down (4) to short-circuit the load, thereby isolating it from the voltage source, and a controller (3) operable while the source is isolated from the load, to activate at least one of the devices at the same time, a current flowing through the activated switching device or through each activated switching device that can be measured to verify whether the activated switching device or each activated switching device is functioning properly.
