The family of silver-metal oxide contact materials includes the material groups: silver-cadmium oxide (DODURIT Ag/CdO), silver-tin oxide (SISTADOX), and silverzinc oxide (DODURIT ZnO). Because of their very good contact and switching properties like high resistance against welding, low contact resistance, and high arc erosion resistance, silver-metal oxides have gained an outstanding position in a broad field of applications. They mainly are used in low voltage electrical switching devices like relays, installation and distribution switches, appliances, industrial controls, motor controls, and protective devices <xr id="tab:Application Examples of Silver–Metal Oxide Materials"/><!--(Table 2.31)-->.
