Abstract
An improved method for manufacturing contacts with precious metal coating on a limited area of its surface, characterized in that a precious metal coating is arranged on one of the faces of a hexagonal section bar of an electrically conductive metal, because said bar is then laminated or stretched, or both, by converting it into a wire or wire profile, the wire then being welded with electric welding in different predetermined lengths and cut and because the piece of welded wire is shaped in a stamping operation without cutting.
