Abstract

Switch contacts (see Division H2) comprise a first contact element containing 65-80% gold and 35-20% silver, with up to 30% of the silver being replaceable by copper, and a second contact element containing 40% to less than 60% palladium and the remainder silver, with up to 20% of the silver being replaceable by metals, particularly copper, which form mixed crystals with the binary silver-palladium alloy.
