Electrical layer contact element and method for manufacturing same

摘要

A layer of silver-metal oxide, a layer of gold or a gold alloy and, a layer of rhodium or ruthenium are electrolytically produced on a metal base, preferably in the form of a wire. The gold alloy is partially diffused into the silver-metal oxide layer by an annealing process at a temperature between 300 DEG and 900 DEG C. As a result, a low-impedance and burn-up resistant contact coated element is provided for employment in weak current relays.
