ABSTRACT:
A method and apparatus is provided to produce a gold, inlaid contact surface for an electrical contact device by welding gold ribbon segments to the contact device wire base prior to the coining, trimming, slotting and various other forming operations which transform the wire base into a finished contact device. The apparatus features a sequential arrangement of gripping devices which manipulate the gold ribbon for processing as stated above, a welding apparatus for combining the gold ribbon segment with the contact wire base, a cutting device for cutting the gold ribbon and apparatus for forming the finished electrical contact device. The product features a formed contact device including a wire support member and a contact material simultaneously formed and flattened, to provide a minimum amount of inlaid or coined gold for effecting desirable contact characteristics. The gain of the contact material is transversely oriented to the grain of the wire support member for improved flexure performance of the product and the contact material is substantially planar with the wire support to avoid chipping.
