Abstract

L'invention concerne un contacteur non consommateur d'énergie qui est principalement composé d'un électroaimant, d'un cadre de support de contact mobile (36), de contacts mobiles (33), de contacts fixes (34), et d'un module de verrouillage (7). Le contacteur utilise l'interaction entre une plaque coulissante (8) et une pièce de verrouillage (9) pour permettre à une bobine électromagnétique (2) d'être mise sous tension instantanément une fois de telle sorte que le contacteur est dans un état de connexion, et lorsqu'elle est à nouveau mise sous tension instantanément, le contacteur est placé dans un état de rupture. Ainsi, l'inconvénient de la consommation d'énergie générée lorsqu'une bobine d'électroaimant de contacteur est actionnée par rapport à des appareils électriques peut être évité de manière efficace, ce qui permet de réduire efficacement la consommation d'énergie électrique et la pollution sonore étant donné que le contacteur fonctionne de manière silencieuse.
