Bimetal Contact Rivets are advanced electrical contact components specifically engineered for low and medium voltage switching applications. These rivets are composed of two different metals—typically a silver-based contact layer and a high-conductivity copper base.
This dual-metal construction provides an optimal balance of excellent electrical conductivity and strong mechanical strength, making them a preferred choice in modern electrical and electronic systems.
