Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a switch contact provided with a consumption-resistant contact face having high contact resistance stability and especially, a long service life by using an alloy composed of specified ratios of Pd, Ru and Au. SOLUTION: An alloy having a compsn. composed of, by weight, 25 to 35% Pd, 1 to 5% Ru and the balance Au is prepd. Preferably, it contains Cu up to 0.5% as a component in addition. The alloy is a contact material having extremely high consumption resistance based on planar corrosion at the time of individual switching stages and therefore, the defect in capable of being opened in the case of switching at the time of loading and cold welding in the case of dry switching are largely checked by the reduction of the adhesion between the mutual contacts. As a result, the coating for the contact of a corresponding miniature switch and the service life of the switch are remarkably improved. The other advantages of the alloy lie in the stable contact resistance and the economization of gold.
