Abstract

Clavier à touches basculantes avec dispositif de commutation constitué par une couche isolante flexible 24. Cette couche isolante 24 est pourvue sur une de ces surfaces d'un circuit conducteur 26 et est conçue de manière à former une grille de protubérances 28 dont chacune constitue un commutateur séparé pouvant être déformé instantanément selon un mouvement à déclic bien perceptible par l'utilisateur, pour établir un contact entre le circuit conducteur 26 et un second circuit conducteur 36. Application aux appareils électroniques tels que calculatrices, ordinateurs, téléphones etc.
