Title (EN) BISTABLE MICRO-SWITCH AND METHOD OF MANUFACTURING THE SAME
(FR) MICROCOMMUTATEUR BISTABLE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)The present invention provides a bistable switch using a shape memory alloy, and a method for manufacturing the same. More specifically, the bistable switch includes a substrate having at least one power source; a flexible sheet having a first distal end attached to the substrate; a bridge contact formed at a second and opposite distal end of the flexible sheet; and at least one heat activated element connected to a first surface of the flexible sheet and between the second distal end and the power source. During operation, current from the power source passing through the heat activated element to indirectly bend the flexible sheet and short the signal contacts on the substrate with a sustainable force.
(FR)L'invention concerne un commutateur bistable utilisant un alliage à mémoire de forme et son procédé de fabrication. L'invention concerne plus particulièrement un commutateur bistable comprenant un substrat ayant au moins une alimentation ; une feuille souple dont une première extrémité distale est fixée au substrat ; un montage en pont formé au niveau d'une seconde extrémité distale opposée de la feuille souple et au moins un élément thermoactivé connecté à une première surface de la feuille souple et venant entre la seconde extrémité distale et l'alimentation. En cours d'opération, le courant provenant de l'alimentation circulant à travers l'élément thermoactivé fléchit indirectement la feuille souple et raccourcit les signaux entrant en contact sur le substrat sous l'effet d'une force renouvelable.
