Abstract

Relais électrique constitué par une pluralité d'électrodes scellées dans un tube de matériau isolant, et dont au moins une électrode est dotée d'élasticité. Pour obtenir une position stable à choisir entre deux positions dites << repos >> et << travail >> de la lame souple commune, l'invention prévoit de déséquilibrer les forces qui agissent sur la lame souple, en créant un circuit annexe de flux magnétique qui se referme préférentiellement par une électrode dite de << repos >>, en raison d'une dissymétrie de réluctance entre les électrodes << repos >> et << travail >>. Selon l'invention cette dissymétrie est créée au moyen d'un aimant qui est en contact avec l'électrode << repos >> et dont l'entrefer avec l'électrode << travail >> est déterminé avec précision par une cale d'épaisseur en matériau amagnétique et isolant électriquement, le réglage final de la sensibilité du relais étant obtenu par l'ajustement du flux de l'aimant.Electrical relay constituted by a plurality of electrodes sealed in a tube of insulating material, and of which at least one electrode is provided with elasticity. To obtain a stable position to be chosen between two so-called "rest" and "work" positions of the common flexible strip, the invention provides for unbalancing the forces acting on the flexible strip, by creating an auxiliary flow circuit. magnetic which is preferably closed by a so-called "rest" electrode, due to a reluctance dissymmetry between the "rest" and "work" electrodes. According to the invention, this asymmetry is created by means of a magnet which is in contact with the "rest" electrode and whose air gap with the "working" electrode is determined with precision by a wedge of thickness in non-magnetic and electrically insulating material, the final adjustment of the sensitivity of the relay being obtained by adjusting the flux of the magnet.
