Bi-metal and Tri-metal Rivets are used in all kinds of switching devices to control the flow of electricity.
Bi-metal rivets are the contacts where the base metal and contact material are welded together for strong and reliable bonding whereas Tri-metal rivets are a parallel setup of cold forging machines where the two metals are forged together without welding process.
The different types of rivets are as follows:
Regular Solid Contacts
Clad Contacts to cut down costs
For riveting on to fragile supports
Specially designed contacts for automatic feeder lines
