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 dieletric intermidiate circuit spacer (20) disposed therebetween. The intermidiate 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 intermidiate circuit spacer, and second x-axis (30) electrodes are formed on the lower surface of the intermidiate circuit spacer. Conductive adhesive (58, 64) is applied between the intermidiate circuitspacer and the top and bottom membranes to secure the intermidiate spacer in place with the x- and y-axis electrodes in electrical contact with the top and bottom membranes, respectively.
