Abstract

L'invention concerne une armature de condensateur élastiquement déformable à utiliser dans une touche capacitive, et qui est attachée à un substrat stationnaire. Selon l'invention, l'armature comprend une structure unitaire 50 en un matériau élastique et électriquement conducteur qui a une partie 52 formant armature de condensateur active, une partie 54 formant ressort de surcourse en forme de patte, définie par une fente à travers la partie 52, et une partie étroite et allongée formant ressort à lame dont une extrémité se confond avec la partie formant armature active, la partie formant ressort à lame s'étendant le long d'une partie du bord de la partie formant armature en en étant espacée. L'invention s'applique notamment aux touches capacitives pour terminaux d ordinateurs.
