<p>The preferred embodiment apparatus employs an interior trim panel (23) and an electrical harness (25) for use in an automative vehicle. In one aspect of the present invention, the interior trim panel has a generally rigid substrate (27) covered by an aesthetically pleasing covering material (29). In another aspect of the present invention, an electrical harness (25) is provided with integrally created switch contacts (71; 73; 91; 101) and integrally created connector terminals (271). The invention includes an electrical harness (25) made by injection molding a catalytic platable polymeric resin (41) in a first injection mold. Next, a second shot of a non-catalytic polymeric resin (43) is injection molded over portions of the catalytic platable polymeric resin (41) in a second mold. The surfaces of catalytic platable polymeric resin (41) which remain exposed after overmolding of non-catalytic polymeric resin (43) define multiple circuits (45). An adhesion promoter is applied to these exposed circuit areas and then these exposed surfaces are plated with an electroless copper which is attracted to the catalyst in catalytic platable resin (41). The polymeric resins are preferably selected from those having a relatively high heat deflection temperature. The non-catalytic polymeric resin (43) acts as an insulator while the raised and plated portions of catalytic platable polymeric resin (41) act as electricity carrying, conductive circuits or traces (45).</p> |
