摘要:
A membrane switch (10) having a top membrane (12) with a lower conductive surface (16), a bottom membrane (14) with an upper conductive surface (18), and a dielectric intermediate circuit spacer (20) disposed therebetween. The intermediate circuit spacer includes a central aperture (24) and defines upper and lower surfaces (28 and 32). First y-axis electrodes (26) are formed on the upper surface of the intermediate circuit spacer, and second x-axis (30) electrodes are formed on the lower surface of the intermediate circuit spacer. Conductive adhesive (58, 64) is applied between the intermediate circuit spacer and the top and bottom membranes to secure the intermediate spacer in place with the x- and y-axis electrodes in electrical contact with the top and bottom membranes, respectively.
