Abstract

L'invention concerne un dispositif thermosensible à action brusque. Le dispositif comporte une lame-ressort 20 ayant une surface normalement convexe qui est maintenue sous une forme concave par une bande de tension 36 fixée à ses extrémités 40, 44 à la lame. La bande peut être chauffée par une résistance électrique 46 en contact direct avec sa face opposée à celle voisine de la lame; la bande chauffée se dilate et se détend alors permettant à la lame de reprendre sa forme convexe et d'actionner, par exemple, un interrupteur, et, dans cette position, la bande est en contact thermique direct avec la lame qui joue le rôle d'élément dissipateur de chaleur. Application aux relais thermiques.
