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.
