Electrical Contacts

Silver rivet and Ag/Cu bimetal rivet: Pure silver has a high level of electrical and thermal conductivity, good plasticityand arc corrosion resistance, as well as a very low contact resistance. It iseasily soldered and is the ideal contactor material for continuous, enclosed electricconnectors. It is one of the most widely used materials in small capacityand low voltage electrical appliances, such as automatic control switches, thermostats,baking machines, oven, timers, thermal relays, and computers. AgCu rivet: This contact has good electrical conductivity and its surface is not liable to oxidization.The addition of 3 - 28% copper may remarkably improve the silver's flameresistance. Hence, copper contact material may be used in current strength upto 16A. The addition of copper, especially of high copper content, for example10%, will greatly reduce material transferring during DC working conditions. Itis widely used in AC contactors, relays, electric tool switches, buttons, timers,and
