Abstract
A method is disclosed for improving the production of electrical switch contacts, in particular for vacuum tubes. In the method, an electrical or electromagnetic field assists and/or effects a sintering process. In the method, the sintering process takes place on a metallic carrier, and via the method, semi-finished contact elements for electrical switch contacts, contact elements for electrical switch contacts, and/or electrical switch contacts, in particular for vacuum tubes, are produced.
