How to Choice a suitable silver material for your switch？

Is  Ag, AgW, AgNi, AgSnO2, AgCdO, AgZnO2 or AgSnO2In2O3?

Good conductivity, stable performance，for ≤10A ------Ag

Burn resistance ,hardness requirement ------AgSnO2In2O3

Low contact resistance, welding resistance------AgNi

Good thermal conductivity, easy welding processing-----AgW

Corrosion-resistant , environmentally friendly-----AgSnO2 /AgZnO2

Good conductivity，cost effective-----AgCdO
