Abstract

La présente invention concerne un clavier à touches et à témoins lumineux. Un tel clavier comporte les uns au-dessus des autres : une plaque support comportant une plaque métallique 1 Sur laquelle est déposée une couche 2 de matériau diélectrique recouvert de dépôts conducteurs électroluminescents 3 et de zones métallisées conductrices, une feuille intercalaire 12 isolante, percée d'ouvertures 14 à la verticale des zones métallisées de la plaque support, une plaque supérieure Il dont au moins les parties en regard des ouvertures 14 de la plaque intercalaire 12 sont porteuses de zones métallisées. Ce clavier est utilisé par exemple dans les boitiers de commande ou télécommande.The present invention relates to a keyboard with keys and indicator lights. Such a keyboard comprises, one above the other: a support plate comprising a metal plate 1 On which is deposited a layer 2 of dielectric material covered with electroluminescent conductive deposits 3 and conductive metallized areas, an insulating insert sheet 12, pierced with 'openings 14 vertically to the metallized areas of the support plate, an upper plate II of which at least the parts facing the openings 14 of the intermediate plate 12 carry metallized areas. This keyboard is used for example in control or remote control units.
