ABSTRACT:
An instrument panel for automotive vehicles is molded of an insulating plastics material and carries electrical conductors on the rear surface leading to indicating and control instruments on the front. Several grooves on the rear surface, one for each conductor, are coated along their flanks with a conductive material such as a conductive paint to form the conductors. Cavities extending through the panel allow contact springs to connect the conductors on the rear to the instruments on the front.
