Standard environmentally friendly silver contacts:

Surface materials: pure silver, fine-grained silver, silver nickel, silver copper, silver cadmium oxide, silver zinc oxide, silver tin oxide, silver tin oxide indium and other substrates: red copper, copper nickel, etc; Can be electroplated with gold, silver, nickel, etc;

Application:

AgCdo (silver cadmium oxide) series: light switches, circuit breakers, electromagnetic switches, micro switches, motor protectors, line starters, fuse less circuit breaker control switches, high load relays, cam switches, etc

AgSno (silver tin oxide) series: automotive circuit breakers, micro switches, electromagnetic switches, various switches and high-energy bracelet points, household circuit breakers, etc.

AgNi (silver nickel) series: low-power switch, static bracelet point, line starter, circuit breaker microswitch, control switch, temperature regulator, thermostat.

AgSnOlnO (silver tin oxide indium) series: circuit breakers, electromagnetic switches, various switches, and high-precision bracelet points.

Sterling silver and others: automatic control switches, thermostats, baking machines, ovens, timers, medium power switches, etc

Advantages:

AgCdo (silver cadmium oxide) series: It has good wear resistance, resistance to fusion welding, and conductivity and thermal conductivity, with low and stable contact resistance.

AgSno (silver tin oxide) series: high thermal stability, heat resistance, arc erosion resistance and melting resistance, long service life

AgNi (silver nickel) series: used for DC contacts, it has good conductivity and electrothermal properties, low contact resistance, stable surface, and small and uniform electrical loss.

AgSnOlnO (silver tin oxide indium) series: It has good thermal stability and higher hardness, and has better fusion welding performance and durable burning resistance.

Pure silver: has the best conductivity, but is easy to stick and solder.
