ABSTRACT:
A contact element is produced by sonically welding one or more contact pieces onto a carrier, an intermediate layer, for example of aluminium foil, being interposed between the contact piece and the carrier prior to such welding in order to assist in the welding of the contact pieces made of material which would otherwise be difficult to weld. Typical frequencies of sonic welding lie in the range between 20 kHz and 50 Hz.
