Abstract

L'invention concerne les matrices d'interrupteurs qui permettent à un opérateur de désigner un point sur une surface. La matrice d'interrupteurs de l'invention comprend un substrat 10 qui porte un ensemble de bandes conductrices parallèles, comme par exemple la bande 24; et une membrane 11 qui est tendue sur le substrat, à une certaine distance de ce dernier, et qui porte un second ensemble de bandes conductrices paralleles 12-16, orthogonales aux bandes du premier ensemble. Une grille isolante 45 est intercallée entre la membrane et le substrat pour éviter tout contact intempestif entre les deux ensembles de bandes. Application aux périphériques d'ordinateurs.The invention relates to switch arrays that allow an operator to designate a point on a surface. The matrix of switches of the invention comprises a substrate 10 which carries a set of parallel conductive strips, such as for example strip 24; and a membrane 11 which is stretched over the substrate, at a certain distance from the latter, and which carries a second set of parallel conductive strips 12-16, orthogonal to the strips of the first set. An insulating grid 45 is interposed between the membrane and the substrate to prevent any untimely contact between the two sets of strips. Application to computer peripherals.
