Title
(EN) ELECTRICAL CONTACT SYSTEM FOR A SWITCHING DEVICE
(FR) SYSTÈME DE CONTACT ÉLECTRIQUE POUR DISPOSITIF DE COMMUTATION
Abstract
(EN)
Electrical contact system (2) for a switching device (1) includes at least one pair of contacts (3) having a fixed contact piece (4) and a contact piece (5). The contact piece (5) is coupled to a slide (15). A planar contact piece carrier (7) extends in the longitudinal section thereof and is attached at the first end (11) to a second busbar (13). A second end (12) of the contact piece carrier (7) is coupled to the slide (5). A spring element (18) having a first spring arm section (22) and a second spring arm section (23) and a pressure region (24) arranged therebetween in the area of the movable contact piece (5). The first spring arm section (22) is attached to the second busbar (13) at the first end (11). The second spring arm section (23) is also coupled at the free end (21) thereof to the slide (15).
(FR)
L'invention concerne un système de contact électrique (2) pour un dispositif de commutation (1) comprenant au moins une paire de contacts (3) ayant une pièce de contact fixe (4) et une pièce de contact (5). La pièce de contact (5) est couplée à un coulisseau (15). Un support de pièce de contact planaire (7) s'étend dans sa section longitudinale et est fixé au niveau de la première extrémité (11) à une deuxième barre omnibus (13). Une seconde extrémité (12) du support de pièce de contact (7) est couplée au coulisseau (5). Un élément ressort (18) ayant une première section de bras de ressort (22) et une seconde section de bras de ressort (23) et une région de pression (24) disposée entre ceux-ci dans la zone de la pièce de contact mobile (5). La première section de bras de ressort (22) est fixée à la seconde barre omnibus (13) au niveau de la première extrémité (11). La seconde section de bras de ressort (23) est également couplée au niveau de l'extrémité libre (21) de celui-ci au coulisseau (15).
