Abstract

Un ensemble de touches rétroéclairées d'épaisseur réduite pour un dispositif électronique et un dispositif électronique comportant un tel ensemble de touches sont présentés. L'ensemble de touches utilise un puits local (creux) dans une plaque de fond de l'ensemble de touches pour diminuer la source d'éclairage (p. ex., DEL) et une carte de circuits imprimés souple relativement à la plaque de fond. L'ensemble de touches décrit aux présentes offre un espace principal convenable pour la source d'éclairage tout en permettant à l'épaisseur globale de l'ensemble de touches d'être réduite comparativement à des modèles de touches rétroéclairées.
