Abstract

L'invention concerne un dispositif de commutation électrique comprenant au moins deux éléments de contact ( 1a, 1b, 1c, 1e, 1f) qui sont en contact électroconducteur dans une première position de commutation et séparés électriquement les uns des autres dans une seconde position de commutation, ainsi qu'un élément d'actionnement (2). Ledit élément d'actionnement (2) présente un matériau à mémoire de forme qui lui permet de passer d'une des deux positions de commutation respectives à l'autre, sous l'effet de chauffage.
