Abstract

L'invention se rapporte à un système de contact s'adressant particulièrement à des disjoncteurs basse tension limiteurs de courant, ce système de contact possédant un contact mobile allongé (10) qui, sur son point médian, est monté rotatif autour d'un axe de rotation (A) dont le sens est perpendiculaire à l'axe longitudinal du contact. Le contact mobile coopère avec deux contacts fixes (20, 21) qui sont disposés sur les côtés opposés du contact mobile. Lorsque ce dispositif de commutation est en position fermée, le contact mobile s'appuie contre les contacts fixes à l'aide d'un ressort de torsion (18) qui s'étend parallèlement à l'axe de rotation du contact mobile et qui, sur l'un des côtés du contact mobile, est relié à celui-ci et, sur le côté opposé, est relié au support du dispositif de commutation.
