Electrical Silver Contacts

Rugged & Reliable Power Connections - MELTRIC
For example, the silver-nickel contacts withstand wear and maintain excellent conductivity even when oxidized. Silver-nickel only welds at extremely high temperature and pressure, and thus, also withstands arcs very well. In contrast, competitors brass contacts are not arc resistant and, as shown in the chart above, their electrical performance ... View This Document

The contacts become so encrusted that the switch is unable to close the circuit due to the high contact resistance. The solution to this is plating the contacts with gold, which does not tarnish, thus assuring the full electrical life of the switch. Power Level ~ 100mA to 10 amps @ 125V AC Silver contacts are recommended for electrical levels ... Doc Viewer

Contact Lubricants - Electrolube
Contact lubricants are used extensively for connectors. Connectors in early automotive applications were plagued with “fretting corrosion” problems. Although tin and silver plated contacts are more commonly used, gold plated contacts are also apparent in some connector designs. Gold is a soft material and can exaggerate fretting corrosion. ...
