Silver electrical contacts refer to the electronic appliances when opening and closing, separation and mutual contact of intersections, because the metal conductor terminals at the instant of the contact prone to moments of fever and spark, prompting them to contact point in the process of using multiple frequency, prone to oxidation and electrolysis, so will increasing the thickness of the contact point, or manufactured polymer metal (copper and multiple) with different material, so will called silver contact.
Silver cadmium electrical contact(AgCdO) has high fusion welding resistance, electric wear resistance and low contact resistance.In some specific fields, so far, no other material can be replaced. Increase Cadmium oxide content can improve the material fusion welding resistance, but will increase the contact resistance and the temperature rise, meanwhile reduce the material of plasticity.
Silver contact points also called a contact tip, button or terminals. It is an electrical circuit component found in electrical switches, relays and breakers. It is composed of two pieces of electrically conductive metal that pass electrical current or insulate when the gap between them is closed or open. The gap must be an insulating medium of air, vacuum, oil,SF6or other electrically insulatingfluid.
The moving contact rivets control the power directly or indirectly, switching electrical power through arelayor the supply ofnatural gasorfuel oilthrough an electrically operated valve.
AgSnO2 silver contacts are widely used in large capacity contactor, power relay, medium and small capacity of low voltage circuit breaker, and automobile electronics etc
AgCdO contact rivet includes AgCdO10, AgCdO12, AgCdO15,AgCdO20 and this kind of electrical contact has one of the most important materials in silver - metal oxide contact material
