Abstract
The invention discloses a semi-finished product for making plug-in contacts in plug-in connectors for electric DC power systems in motor vehicles which are operated at a nominal voltage at which electric arcing may occur, having an electrically conductive main body made of a non-precious metallic material that carries, at least in part, a contact-making coating of a material more precious than the material of the main body. It is provided according to the invention that the coating has thickness of at least 0.3 μm and consists of silver or of a silver-based alloy with an addition that will not form an alloy with silver or with the silver-based alloy, or will at best form a precipitation alloy, and which has a higher melting point than silver.
