ABSTRACT:
A touch sensitive device includes an arrangement of conductors in combination with a pressure sensitive electrically conductive material. The conductors appear in a cross-wire matrix imprinted on the top and bottom surfaces of a rigid printed circuit board. The pressure sensitive electrically conductive material is positioned over the cross-wire matrix of spaced electrical conductors. The resulting arrangement defines a plurality of touch sensitive locations which may be used for uniquely entering information in a data entry system.
