Abstract

A direct current connection apparatus, especially a relay for motor vehicles, with noble metal contacts, using for this a contact consisting of a thin layer of a palladium-copper alloy with a palladium content of approximately 60% by weight, and the rest copper, and in a copper layer located below, characterized in that the anode contact consists of a contact layer based on the palladium-copper alloy in ordered phase, with a layer thickness of 0.1 0.15 mm, and in the copper layer below, and because the cathode contact consists of silver or a silver alloy.
