Abstract

The disclosure relates to a method for production of a component, such as a contact piece, for a switchgear assembly. To introduce a slot and apply a contact outer contour directly during the powder-metallurgical production process of the contact material, contouring in the form of a slot or slots is introduced into the powder-metal material, which is located in a mold, essentially in a direction parallel to a normal to a surface of the component, to form the component with a slot.
