Abstract

A direct current control device, in particular a flashing light signal thermal transmitter for motor vehicles, with precious metal contacts, characterized in that the anode contact consists of a silver-copper alloy with a copper content of at least minus 5% by weight, and fine grain silver cathodic contact with a nickel content of 0.1 to 0.2% by weight.
