What are Riveted Contact Copper Stamping Assemblies?
Designed for the demanding operating conditions of power distribution and control hardware, these Riveted Contact Copper Stamping Assemblies utilize high-purity base materials and precision mechanical forming processes to ensure stable circuit switching. Functioning as integrated current-carrying bridge components, they feature contacts-produced via cold heading-securely fastened to highly conductive copper stampings through mechanical riveting or welding, thereby minimizing contact resistance and heat accumulation. These assemblies are suitable for the mass production of heavy-duty switchgear, meeting the rigorous standards of modern industrial OEMs for high bond strength and low resistivity. Factory-direct production enables flexible batch manufacturing and full material traceability, with customizable structural designs tailored to various mechanical load requirements.

Application Areas of In-Die Riveted Moving Contact Assembly
Electromechanical Relay Assemblies
Applicable to conductive terminal constructions of electromechanical relays, this part adopts stamped copper to form the terminal body, with a riveted contact realizing the designated electrical interface for the relay‑switching circuit.
Automotive Electronic Control
The assembly is suitable for stamped copper terminals and riveted contact structures within automotive electronic control modules. Specific materials, contact specifications, and dimensional requirements are determined by the module's engineering drawings.
Industrial Automation Control
Industrial relays and control components can utilize these riveted copper stampings for sensor interfaces, actuator control circuits, and other electromechanical connection structures. Specific contact materials and electrical testing limits depend on the control circuit design.
Power Control Equipment
This structural design is applicable to power control components that require a stamped copper conductive base combined with a mechanically fixed electrical contact. Suitability should be verified based on the equipment's current, voltage, temperature, and switching operating conditions.
