Electrical Bimetal Contact Rivet, 
1. Feature
The unique post-processing technology, ensure that the contact surface is clean without foreign materials.Contact posesses low contact resistance, high bonding strength. When three lagers contact are used as switch contacts, you can greatly reduce the using cost. Stable and reliable suply of contact material, which ensures the quality of contact. All materials can be eletroplated with gold or silver.
