For switch-over contacts part of the rivet shank is formed into the secondary rivet head. To minimize deformation of the contact blade carriers, especially thin ones, this head forming is often performed by orbital riveting.
The insertion and forming of wire segments can be easily integrated into stamp and bending multi-slide tooling <xr id="fig:Direct press-insertion of wire segmentsDirect_press_insertion_of_wire_segments"/> (Fig. 3.7). Compared to the use of composite rivets this process uses more precious contact material but for silver based contact materials these costs or often offset by higher and more efficient manufacturing speeds. For the more brittle Ag/SnO<sub>2</sub> materials however close attention must be paid to the danger of crack formation.
