CA 2288827

The relay has a base body (1), an electromagnet system having a coil (1, 10), core (2) and armature (3), as well as a contact arrangement having at least one stationary contact spring (5, 9) and at least one moving contact spring (6). The contact springs are each designed as planar sheet-metal parts and are anchored in the base body approximately in the same plane, without any permanent bending. In order to make contact, they are provided with an overlap by means of L-shaped end sections; in addition, prestressing of the stationary contact springs (5, 9) is produced by in each case one stop (18, 20) on the base body.

L'invention concerne un relais comportant un corps de base (1), un système d'électro-aimant avec une bobine (1, 10), un noyau (2) et une armature (3), ainsi qu'une configuration de contacts présentant au moins un ressort de contact fixe (5, 9) et au moins un ressort de contact mobile (6). Les bancs de contact se présentent chacun sous forme de pièce de tôle plane ancrée dans le corps de base, approximativement dans le même plan, sans qu'il subsiste de cintrage. Des sections terminales en L permettent de produire un chevauchement pour établir le contact. Une butée (18, 20) produit dans chaque cas une précontrainte pour les bancs de contact fixes (5, 9) au niveau du corps de base.
