Abstract

Le dispositif est caractérisé en ce qu'il est prévu sur la surface enveloppe du galet de contact (2) lorsqu'il vient d'etre fabriqué , au moins une mince couche annulaire (4,5) d'argent, qui fait légèrement saillie par rapport à la surface enveloppe, tandis qu'il est prévu sur la surface du contact fixe (3) à peu près dans le milieu de celui-ci sur le trajet parcouru par la couche annulaire d'argent (4,5) des galets de contact, une couche d'argent partielle également fine (7, 8) d'une étendue partielle telle que dans la position de repos du dispositif de contact, la couche annulaire d'argent du galet de contact vient s'appliquer sur la couche partielle d'argent de la surface du contact fixe, l'épaisseur des couches d'argent étant d'environ 5 à 50 microns.The device is characterized in that it is provided on the envelope surface of the contact roller (2) when it has just been manufactured, at least one thin annular layer (4,5) of silver, which protrudes slightly relative to the envelope surface, while it is provided on the surface of the fixed contact (3) approximately in the middle of the latter on the path traveled by the annular silver layer (4,5) of the rollers contact, an equally thin partial silver layer (7, 8) of a partial extent such that in the rest position of the contact device, the annular silver layer of the contact roller comes to be applied on the layer partial silver of the surface of the fixed contact, the thickness of the silver layers being approximately 5 to 50 microns.
