Zusammenfassung:The invention relates to a method for production of a contact piece for a switchgear assembly, and to a contact piece itself, as claimed in the preamble of patent claims 1 and 15. In order in this case to introduce the slot and to apply a contact outer contour directly during the powder-metallurgical production process of the contact material, the invention proposes that contouring, in particular via a thin plastic film, in the form of a slot or slots is introduced into the component and/or into the contact piece and/or into the powder-metal material, which is located in a mold, essentially in a direction parallel to the normal to the surface of the component or contact piece.
