The Electrical Contact Rivet is a widely used fastener in relays, thermostats, small AC contactors, leakage protectors, electrical tool switches, button switches, etc. They feature advantages such as welding-resistance, high temperature- resistance and low-resistance. It consists of two different metals which are bound around each other. It has a high level of electrical and thermal conductivity, good plasticity and arc corrosion resistance, as well as a very low contact resistance. Electrical Contact Rivet is very useful.
