ABSTRACT:
A precious metal electrical contact dot formed from a ribbon of base metal having one substantially flat side and one cylindrically rounded side has precious metal plated on the rounded side and a central ridge formed on the substantially flat side. A tab is formed by cutting a short length from the end of the ribbon, and the substantially flat side of the tab is resistance-welded to the wall of an electrical socket. The wall may be essentially copper, the base metal essentially nickel, and the precious metal essentially gold. A precious metal, gold, wash may be applied over the tab and adjacent wall surface.
