Abstract: A membrane switch (10) is disclosed having a bottom membrane (12) with an upper conductive surface (16), a top membrane (14) with a lower conductive surface (18), and an intermediate spacer (20) disposed therebetween. The intermediate spacer includes a central aperture (24) and is formed of an intermediate substrate (21) having a lower surface (26) and an upper surface (28). First y-axis electrodes (30A, 30B) including first contact portions (31A, 31B) and second x-axis electrodes (34A, 34B) including second contact portions (38A, 38B) are both formed on the upper surface of the intermediate substrate. The intermediate spacer further includes an upper adhesive layer (45) including predefined first apertures (50) adapted to overlie the first contact portions of the y-axis electrodes and predefined second apertures (47) adapted to overlie the second contact portions of the x-axis electrodes, and a lower adhesive layer (43). Preferably after the intermediate spacer is assembled, at least one hole (39) is defined through each of the first contact portions, extending through the intermediate substrate and the lower adhesive layer. Then conductive epoxy material (41) is poured into the first aperture and the hole so as to provide an electrical conduction path between the first contact portion of the y-axis electrode and the lower adhesive layer. Similarly, conductive epoxy material is poured into the second aperture predefined through the upper adhesive layer so as to provide an electrical conduction path between the second contact portion of the x-axis electrode and the upper adhesive layer. When the intermediate spacer thus constructed is secured between the bottom and top membranes, the y-axis and x-axis electrodes are in electrical contact with the bottom and top membranes, respectively.
