    Abstract: An improved electrical switch device, comprising a first sheet of a transparent, electrically insulating material, having at least one electrical conductor on a surface thereof; a second sheet of transparent, electrically insulating material, having at least one electrical conductor on a surface thereof; and a separating sheet, of electrically insulating material, having at least one hole therethrough, the first, second and separating sheets being arranged in superposed relation, with the first and second leaves on opposite sides of the separating sheet, the conductors being of the first and second sheets adjacent to the separating sheet and aligned, each with at least one hole of the separating sheet, whereby, by applying a pressure to the first sheet, the conductors of the first and second sheets can be pushed into mutual contact through a hole in the separating sheet, characterized in that the first and second sheets are made of a cellulose acetate material, the conductors having been formed on the surfaces thereof by electro-deposition.
