Riveted stamped contact parts are manufactured with the use of contact rivets which are transferred over suitable feed mechanisms correctly oriented into holes punched into the carrier <xr id="fig:Examples of riveted stamped parts"/> (Fig. 3.19). Frequently also wire or wire segments resp. are used which are subsequently coined and formed into the desired contact shape (see also chapter 3.3.1[[Attachment of Single Contact Parts#Mechanical Attachment Processes| Mechanical Attachment Processes]]). Both attachment methods have their distinct advantages. Using composite or tri-metal rivets allows limiting the use of precious metal custom tailored to the volume needed for specific switching requirements. For wire staking the precious metal usage is usually higher but the staking can be performed at significantly higher production rates and the additional rivet making step is eliminated.
