This contact includes AgCdO10, AgCdO12, AgCdO15, and this kind of electrical contact has one of the most important materials in silver - metal oxide contact material. The fine CdO gives the contact special properties. When the temperature is above900oC, CdO sublimes, which cools the contactor surface and reduces arc energy and extinguishments. In addition, existence of cadmium oxide will improve the welding resistance of the contactor. Its typical applications include low voltage contactors, relays, automatic switch flash relays, auxiliary switch series, timers, starters, breakers and leakage protective switches.
