Abstract

L'invention concerne un appareil de commutation d'énergie électrique empêchant un dysfonctionnement. Dans l'appareil de commutation d'énergie électrique selon l'invention, un induit est disposé de manière adjacente à un organe de formation de trajet magnétique et l'induit est tiré vers l'organe de formation de trajet magnétique par un champ magnétique généré par l'organe de formation de trajet magnétique, et l'induit se déplace vers une position de libération lorsqu'un courant de commande est appliqué à une bobine de stator, et se déplace vers une position de verrouillage en éloignement de l'organe de formation de trajet magnétique lorsque le courant de commande appliqué à une bobine côté fermeture est coupé et le champ magnétique de l'organe de formation de trajet magnétique disparaît de façon à empêcher un mouvement d'un guide d'interverrouillage.
