Silver cadmium oxide is the most important contactor material. Cadmium oxide cools the contactor surface and reduces arc energy, meeting the main requirements of electrical switches on contacts. This product is widely used in contactors of various current ratings, single-pole, dual-pole and multi-pole switches, plastic casing air switches, leakage switches, DC fast switches, cam switches, auto contactors, auto protective switches, optical-controlled switches, indoor thermostats, mini switches, and relays of high breaking capacity, as well as in aerospace industry switches. Features: 1) The electrical contact of this product is made by internally oxidized alloy, has a good electrical corrosion resistance, and a slightly low fusion welding resistance 2) Good electrical and thermal conductivity, low and stable contact resistance 3) The manufacturing process greatly influences performances of electrical contactors
