tri-metal composite button contact widely used in micro switches and breakers protector
Specifications
tri-metal composite button contact
baseband:Cu,Fe,CuNi...
Clad:Ag,FAg,AgNi,AgCdOaaaa
Usage:Micro switches,thermostat,keys
1. Product name: tri-metal composite button contact
2. Materials: AgW,AgNi,AgCdO, AgNiC,AgWC
3. Characteristics
A) Silver graphite contact has a good performance in resistance to contact wedding, low contact resistance and high arc erosion resistance
B) AgWC contact is very hard and sufficient mechanical strength, during arcing a protective gas layer of CO is formed which limits the reaction of oxygen on the contact surface and therefore the formation of metal oxides
