ABSTRACT:
An arrangement for bimetallic contacts, especially bimetallic welded contacts, in which wires of metals having different conductivity, e.g. silver and iron, are butt-welded with one another by electrical resistance welding without noticeable deformation of the connecting point. The wires are then sheared off at both sides of the connecting point. The bimetallic pins are formed by cold-pressing to the final bimetallic contacts whose head cross-sections are larger than the possibly different cross-sections of the wires for the manufacture.
