Abstract

Abstract Translated from French 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. Keyboard with tilting keys with switching device consisting of a flexible insulating layer 24. This insulating layer 24 is provided on one of these surfaces with a conductive circuit 26 and is designed so as to form a grid of protuberances 28 each of which constitutes a switch. separate which can be instantly deformed according to a click movement clearly perceptible by the user, to establish contact between the conductive circuit 26 and a second conductive circuit 36. Application to electronic devices such as calculators, computers, telephones, etc.
