Abstract

L'invention concerne un convertisseur électromécanique. Le convertisseur comprend une extrémité adaptée pour servir comme élément de manoeuvre de la tige, un tampon élastique disposé à l'autre extrémité de ladite tige, une paire d'éléments électrodes conducteurs muni chacun d'une borne et séparés par une fente, et un moyen d'électrodes flexibles de shuntage disposé sur l'extrémité dudit tampon pour être disposé conformémement sur lesdits éléments électrodes. Ledit convertisseur est particulièrement utile dans des dispositifs de traitement de signaux, tels que des machines à écrire ou calculateurs.
