Abstract

L'invention concerne un système d'actionnement électromagnétique. Le système comprend des première (101) et seconde (102) plaques polaires ayant des première (111) et seconde (112) parties de tête, un élément magnétique permanent (104) disposé de telle sorte qu'un premier pôle de l'élément magnétique permanent (104) est en contact avec la première plaque polaire (101) et un second pôle de l'élément magnétique permanent (104) est en contact avec la seconde plaque polaire (102) ; une armature (103) comprenant une partie de contact (113) et un point de pivotement (123) ; et un élément de sollicitation (105) couplé à l'armature et configuré pour exercer un couple sur l'armature pour pousser l'armature de la position fermée à la position ouverte, l'armature (103) étant maintenue dans la position fermée pendant un fonctionnement normal par une force de maintien magnétique entre les première et seconde parties de tête et la partie de contact (113), et le point de pivotement (123) de l'armature (103) n'entrant pas en contact avec les première et seconde plaques polaires.
