Kontak Rivet - 1

Pure silver has a high level of electrical and thermal conductivity, good plasticity and arc corrosion resistance, as well as a very low contact resistance. It is easily soldered and is the ideal contactor material for continuous, enclosed electric connectors. It is one of the most widely used materials in small capacity and low voltage electrical appliances, such as automatic control switches, thermostats, baking machines, oven, timers, thermal relays, and computers.

AgCdO/Cu bimetal rivet:
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, cam switch, relays, automatic switch flash relays, auxiliary switch series, timers, starters, breakers and leakage protective switches.

AgZnO rivet:
The oxide of this contactor is more thermally stable than CdO. Because of the higher stability of ZnO and AgZnO, the contactor material increases the contactor resistance, which would be compensated through structural means, such as a higher contacting force.
Application: Used in relays, contactors, air switches, limiting switches, motor protector, micro-switches, instrumentation, home appliances, automobiles, electrical appliances (light switch, load switch, such as starter motors), such as earth leakage protection switch.

Features:
(1) ZnO, one type of material in AgznO contact, has comparatively higher thermal stability
(2) The welding resistant and resistance against arc erosion of the contact making ZnO material a higher product
(3) The AgZnO contact material has higher welding resistance and low arc erosion with strong magnetic arc blowing under large switching capacity
(4) AgZnO contact material is innocuous and has no pollution to the environment
(5) AgZnO contact material is mostly suitable for contactors and circuit breakers with large capacities

AgCu rivet:
This contact has good electrical conductivity and its surface is not liable to oxidization. The addition of 3 - 30% copper may remarkably improve the silver's flame resistance. Hence, copper contact material may be used in current strength up to 16A. The addition of copper, especially of high copper content, for example 10%, will greatly reduce material transferring during DC working conditions. It is widely used in AC contactors, relays, electric tool switches, buttons, timers, and other household electrical appliances.

AgSnO2In2O3 rivet:
AgSnO2In2O3 is the most ideal environment-protecting material for substituting AgCdO...Because of better stability and higher hardness, AgSnO2In2O3 has better anti-welding and resistance to burning, especially within the oxidation process of acicular oxides precipitate orientation perpendicular to the contact surface of contact is beneficial to the performance. It's widely used in all kinds of contactors, molded case air switch, GFCI, DC Express switches, cam switches, contactors automotive, automotive protection switch, interior thermostat, micro-switches and high-capacity relays, as well as the aviation industry with a variety of switches.
