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.

A contact for a vacuum interrupter of a low, medium or high-voltage switchgear includes a contact rod composed of a first electrically conductive material and extending along a longitudinal axis of the contact, and a contact piece composed of a second electrically conductive material and fastened to an end face of the contact rod. The contact rod and the contact piece are materially bonded to one another at a connecting face. At least one of the contact rod or the contact piece has a wall which delimits the connecting face, rises perpendicularly to the longitudinal axis and is disposed such that the contact piece and the contact rod are also force-lockingly connected to one another by a force acting transversely to the longitudinal axis between the contact piece and the contact rod. A production method for such a contact is also provided.

A switching device includes a housing, an operation member, a plurality of fixed contacts, a plurality of movable contacts, and a snap action mechanism for causing the movable contacts to operate.
