Abstract

L'invention concerne l'industrie du matériel électrique. Dispositif interrupteur comportant un organe conducteur 72 adapte à fermer un circuit entre deux broches d'arrivée de courant 26, 28, un organe de commande d'interrupteur 48 et un premier et un second organes de sollicitation 70, 79 séparés par des moyens d'isolation 50, ledit dispositif présentant un etat de fermeture dans lequel l'organe de commande 48 est dans un premier état et le premier organe de sollicitation 70 exerce sur l'organe conducteur 72 une force de fermeture de circuit, et un état d'ouverture du circuit dans lequel l'organe de commande 48 est dans un second état, le second organe de sollicitation 79 ouvrant le circuit Application notamment aux interrupteurs thermiques fonctionnant par fusion de l'organe de commande.
