Abstract
L'invention concerne un relais piézo-électrique. Il comporte une plaque bimorphe dans laquelle est découpée une fente en forme de U délimitant une armature et un cadre support. Un premier contact est monté à l'extrémité libre de l'armature et un second contact est monté en face de lui, sur une pièce conductrice fixée sur le cadre La plaque bimorphe est polarisée et porte des électrodes superficielles de manière à se déformer sous l'effet d'une tension electrique et à fermer le circuit entre les contacts. L'invention s'applique notamment à des relais commandés par des circuits integres.
