Abstract: A method for producing an electrical contact assembly includes. Providing a contact carrier of a first conductive material, the contact carrier having at least one depression or an aperture. Furthermore, a contact material support of a second conductive material is provided. This contact material support is pressed in the depression or the aperture while at the same time applying an electrical welding voltage to the contact material support and the contact carrier, a pressing-force/welding-current/time profile being chosen such that the contact carrier and the contact material support form a connection including interlocking and/or frictional engagement and a connection including material bonding in one working step.

Abstract: A contact unit for an electromechanical switching device includes a carrier element and a contact element connected to the carrier element. The contact element has a silver-containing layer that provides a contact area for making releasable contact with a further contact area of the switching device depending on a switching state of the switching device. The silver-containing layer includes diamond particles at least in the region of the contact area.
