Abstract (en)
[origin: US4339644A] A low-power electrical contact particularly suitable for switching and plug-in connections. The contact comprises an outer contact layer and a substrate composed of a copper base alloy. The contact layer consists essentially of an alloy of 35-55% by weight gold, 18-33.5% silver, 30-40% palladium, and (i) 1-6% indium, or (ii) 0.5-2% tin together with 0.5-2% indium. An intermediate layer of nickel or copper-nickel may be interposed between the contact layer and the substrate.
