The conductivity of copper only second to silver and superior to all other metals, so it was used as benchmarks for the conductive properties of the material.Not only copper has excellent electrical conductivity, but also high melting point (1083 ℃), good mechanical properties, corrosion resistance, reliable for working , long life for using , it becomes the most widely used conductive material.
The electrical contact componentscan be widely used in switches, relays, thermostats, contactors, disconnector，controllers, timers and other low-voltage apparatus.
