Title (EN) GLASS MEMBRANE TOUCH-CONTROLLED CIRCUIT APPARATUS FOR VOLTAGE SELECTION
(FR) APPAREIL A CIRCUIT COMMANDE AU TOUCHER ET A MEMBRANE DE VERRE, SERVANT A LA SELECTION DE TENSIONS
Abstract:
(EN) A glass membrane touch-controlled circuit apparatus for voltage selection. The apparatus comprises a flexible glass membrane (12) which is spaced by a dielectric layer (34) adhesively joined between the upper flexible glass membrane and a lower, rigid support layer (20). Conductive circuitry (22, 23) is printed onto the surface of the upper flexible gass membrane (12) and corresponding areas of conductive and/or resistive circuitry (26, 27) are printed onto the lower support layer (20). By application of tactile pressure to the upper flexible glass membrane (12), the conductive circuitry printed onto the flexible glass membrane (12) can be moved into a point of momentary contact with the circuitry (27) carried on the lower support layer (20).
(FR) Appareil à circuit commandé au toucher et à membrane de verre servant à la sélection de tensions. L'appareil comprend une couche supérieure constituée d'une membrane de verre flexible (12) qui est séparée, par une couche diélectrique (34) collée, d'une couche inférieure rigide de support (20). Un circuit conducteur (22, 23) est imprimé sur la surface de la membrane de verre flexible (12) et des zones correspondantes d'un circuit conducteur et/ou à résistance sont imprimées sur la couche de support inférieure (20). En appuyant sur la membrane supérieure de verre flexible (12), on peut mettre un point du circuit conducteur imprimé sur la membrane de verre flexible (12) en contact momentané avec le circuit (27) porté par la couche inférieure de support (20).
