A touch sensitive control panel is disclosed which is constructed of a support surface and a graphic display member secured thereto. The support surface has regions of conductive material deposited thereon and the graphic display member has functional indicia printed thereon, there being a layer of adhesive intermediate the graphic display member and the support surface to secure the graphic display member to the support surface with the functional indicia in registration with the conductive material regions. The graphic display member and the adhesive layer form a dielectric medium between the conductive material and a body portion of an operator touching the front surface of the graphic display member. An improved method for manufacturing such a touch panel is also disclosed.

A control panel of the type having a plurality of touch sensitive areas in proximate relationship to corresponding functional indicia, said control panel comprising: a non-conductive support member having a surface; a plurality of regions of conductive material arranged on said support surface; means for providing electrical connections to said plurality of conductive material regions; an optically transparent graphic display member having a front surface and a rear surface, said rear surface having said functional indicia printed thereon in non-conductive material; and adhesive means for adhesively securing said rear surface of said graphic display member to said support surface with said functional indicia in registration with said conductive material regions; said graphic display member and said adhesive means forming a dielectric medium in contact with said conductive material regions so as to provide capacitive coupling between selective ones of said conductive material regions and a body portion of an operator touching said front surface of said graphic display member in an area having an overlying relationship to a selected one of said functional indicia visible through said graphic display member.
