Specifications

 Silver tin oxide (AgSnO2) has an excellent electrical contact materials, stable performance and good resistance to welding arc erosion resistance properties. In the current large (500 ~ 3000A in the current range) conditions, the silver tin oxide (AgSnO2) contact than silver cadmium oxide (AgCdO) contact arc erosion resistance and better ability of the lamp or capacitive load Next, (AgSnO2) of silver tin oxide contact ratio (AgCdO) silver cadmium oxide contacts, (AgNi) Silver Nickel contact demonstrated significantly better anti-welding properties, in exchangeresistive load, silver tin oxide (AgSnO2 ) contact than silver cadmium oxide (AgCdO) contact with the slightly higher contact resistance (due to the small amount of special payments Oxide as an additive, thereby ensuring that its contact resistance is to the extent permitted), but the lights in the DC Circuit 13.5A / Motor (such as automotive relay) Ying with the occasions, they show a low and stable resistance value. DC conditions, and silver cadmium oxide (AgCdO) contact than silver tin oxide (AgSnO2) low electrical contact material with better shift. Silver tin oxide (AgSnO2) electrical contacts are now widely used in large-capacity AC contactors (eg, CJ20, CJ40, 3TF series, etc.), high power AC switch (50KW and above), DC contactors, AC (direct) flow power relay, automotive electronics, and small low-voltage circuit breaker capacity. The main products are AgSnO2 silver tin oxide alloy electrical contacts, AgSnO2 (8 ~ 12) / Cu alloy of silver tin oxide / copper composite electrical contacts, silver tin oxide alloy / copper-nickel alloy-AgSnO2 (8 ~ 12) / CuNi (8 10) composite electrical contacts, etc.
 
electrical contact(electrical rivet, silver electrical contact)contact sheet parts
Mainly used in variousswitches,push button switches, rotary switches, limited switches,rocker switches,clocks, relays, contactors, miniature and small switches and temperature controllers.
