Abstract
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.
