Contacts and conductive carriers, supplied as one assembly.
Contact and carrier together
Combine the specified contact material with a copper or copper-alloy support, with the contact position and assembly geometry defined by your drawing.
Welding and brazing options
Resistance welding and resistance, induction or furnace brazing are available where appropriate. The contact, carrier and joint design determine the manufacturing route.
Stamped or formed supports
Include the carrier's holes, bends and locating features in the assembly specification so the contact and support can be supplied as a finished unit.
Checks matched to the joint
Agree the dimensional and visual checks for the finished assembly. Bonding, shear or cross-section checks are included when specified in the inspection plan.
Welded assembly dimensions
The contact material, support, joint position, and geometry determine the welding or brazing route.
| Dimension | How confirmed |
|---|---|
| Support thickness | Drawing or sample |
| Contact size and position | Drawing or sample |
| Joint location and orientation | Drawing or sample |
| Overall assembly length / width | Drawing or sample |
| Tolerances | Technical review |
Confirm these dimensions and tolerances from the drawing or sample, material system, and project review before production.
- Contact and support material combination
- Joint position, orientation, and key assembly dimensions
- Welding or brazing route selected for the finished part
- Agreed visual, bond, and section checks
Manufacturing & inspection
Manufacturing route
The joining method is selected according to the part design and the required assembly outcome.
- Resistance spot welding where applicable
- Resistance brazing, induction brazing, or furnace brazing where applicable
- Support stamping or forming as required
- Joint positioning and sampling to the approved assembly specification
Inspection focus
Inspection focuses on the joint, geometry, and agreed evidence for the specific assembly.
- Joint position, key dimensions, and overall appearance
- Weld or braze visual condition
- Bonding or shear checks where specified
- Cross-section or metallographic checks when required by the inspection plan
Materials & applications
Material systems
- Specified contact materials
- Copper or copper-alloy support materials
- Silver or specified finished surface conditions
Typical applications
- Relays
- Switches
- Contactors
- Circuit breakers
- Temperature controllers
