Abstract
The contact element is produced by ultrasonic welding one or more contact pieces onto a carrier, an intermediate layer in the form of a metal powder, for example aluminium, being interposed between the contact piece and the carrier prior to such welding in order to assist in the welding of contact pieces made of material which would otherwise be difficult to weld.
