Planar resistive connecting means for the edges of a rectangular resistive graphic area has a higher effective resistance parallel to the edges of the resistive graphic area than that of the resistive graphic area. This higher effective resistance is formed by means of configuring the connecting areas such as by forming outer edges at acute angles with the edges of the resistive graphic area or by forming slits transverse to the edges of the resistive graphic area. There is also disclosed a combination of a resistive graphic area surrounded by a plurality of planar conductors forming multi-bit digital switching facilities operated by a common conductive plane.
