Micro-heteromorphic composite contacts

With the development of relays and switches toward miniaturization, lightweight and highly integrated, special-shaped composite contact strip is a kind of multilayer composite, small cross-section electrical contact material. Its cross-section is irregular, mostly triangular, trapezoidal and other special-shaped. The special- shaped composite contact strip with cross-section area less than 1 square millimeter, referred to as "microstrip", is mainly used in general relays, communication relays, integrated circuit relays, keys, micro-switches, digital switches, circuit breakers, controllers and connectors and other places with high-reliability requirements. It is the core of communication electronic devices.

New Welding Contact

The new type of welding contact is a derivative of special-shaped contact strip with high-quality production technology of special-shaped composite contact strip. Metallurgical bonding is formed between layers, and the bonding strength is high. The surface of electric contact layer is mirror. The thickness of silver layer can be adjusted arbitrarily according to customer's needs. When crossed, the static and dynamic contacts are in line contact. Under the same volume, the silver layer can bear a larger current load than the conventional welding contacts and rivet contacts, thus indirectly saving the use of precious metal materials. The new welding contacts have unique processing technology, such as high interlaminar bonding strength, high surface finish, stable size, small self-weight and not easy to bounce back. It has been proved that the use of the new welding contacts can greatly improve product quality through the use of a number of customers.

Special-shaped composite contact strip

The special-shaped composite contact strip adopts high-quality production technology, forming metallurgical bonding between layers, with high bonding strength and mirror surface of electric contact layer. The thickness of silver layer can be adjusted arbitrarily according to customer's needs. When crossed, the static and dynamic contacts are in line contact. Under the same volume, the silver layer can bear a larger current load than the conventional welding contacts and rivet contacts, thus indirectly saving the use of precious metal materials. Processing technology is unique, with high interlayer bonding strength, high surface finish, size stability, small self-weight, not easy to bounce back and other advantages, after the use of a number of customers, suitable for automated production, its cross-section is irregular, can be multi-layer composite, the size range is wide.
