Contact Properties,
Pure silver has extreme high property of heat and electricity conductibility and very low contact resistance, but well plasticity and anti-erosion of arc. It is easy to be processed and be welded. So it is the ideal contact materials for manu-facturing the continuous-closed type connectors. It is now one of the commonest-used materials in the small capacity low-voltage electrics, such as self-control switches, thermostats, roasters, grills, timers, thermal relays and computers etc.
