Abstract

La présente invention concerne un relais qui comporte une section de point de contact principal, une section de point de contact auxiliaire, une section d'attaque, une section mobile, une section de contact, et une section de paroi. La section de point de contact auxiliaire inclut un point de contact auxiliaire, et est ouverte/fermée en correspondance avec l'ouverture/fermeture de la section de point de contact principal. Dans la section de point de contact auxiliaire circule un courant inférieur à un courant qui circule dans la section de point de contact principal. La section d'attaque génère une force d'attaque pour l'ouverture/fermeture de la section de point de contact principal. La section mobile fonctionne au moyen de la force d'attaque appliquée par la section d'attaque. La section de contact est disposée de telle sorte que la section de contact est en contact avec la section mobile. La section de paroi est disposée en une position bloquant au moins une partie d'un espace reliant le point de contact auxiliaire et la section de contact entre eux.
