Abstract

a. Interrupteur électrique à contacts mobile et fixe solidaires, respectivement d'une barre porte-contact b. Interrupteur caractérisé en ce que les barres porte-contacts sont conformées et disposées reciproquement de façon telle qu'entre l'extrémité de l'une et l'extrémité de l'autre, il s'établisse, dans la phase d'ouverture des contacts, une distance inférieure à celle qui existe, dans la même position respective des barres, entre le contact fixe et le contact mobile, l'arc électrique s'amorçant ainsi entre ces extrémités, et n'intéressent pas les contacts eux-mêmes, ni les autres parties des barres porte-contact, ni les autres parties de l'interrupteur. c. Disposition applicable à tous types d'interrupteurs, même automatiques.at. Electric switch with movable and fixed contacts integral with, respectively, a contact carrier bar b. Switch characterized in that the contact carrier bars are shaped and arranged reciprocally such that between the end of one and the end of the other, it is established, in the contact opening phase , a distance less than that which exists, in the same respective position of the bars, between the fixed contact and the moving contact, the electric arc thus starting between these ends, and do not concern the contacts themselves, nor the other parts of the contact carrier bars, or the other parts of the switch. vs. Provision applicable to all types of switches, even automatic.
