What is the Moving Spring Riveted Component For Relays?
Moving Spring Riveted Component for Relays combines a stamped beryllium copper moving spring with a silver electrical contact through a controlled riveting process. The assembly is intended for industrial control relays where the spring must provide the required elastic movement while the silver contact forms the switching interface. Production covers spring stamping, contact riveting, dimensional inspection, and finished-component supply. Contact geometry, spring profile, rivet location, and assembly dimensions can be produced from customer drawings or approved samples. This structure allows relay manufacturers to source the moving spring and contact as one assembled component rather than managing separate stamped and contact parts.
Riveted Components riveting process features
Advanced cold riveting technology
Abandon traditional hot riveting and adopt a cold riveting process to avoid the adverse effects of high temperature on material properties, retain the original characteristics of the material intact, and ensure the stable performance of the assembly.
High-precision riveting control
With the help of high-precision riveting equipment, the riveting pressure, position, and depth are accurately controlled to ensure the consistency of each riveting point of the Moving Spring Riveted Assembly for Relays and achieve micron-level riveting accuracy.
Wide material adaptability
Whether it is common metal materials or special alloys, this riveting process can be perfectly adapted to effectively improve the connection strength between parts of different materials.

Common Riveting Defects & Quality Verification Items of Relay Moving Spring
Prevention of Contact Tip Eccentricity
During high-speed riveting, optical monitoring systems detect and reject assemblies exhibiting contact tip displacement exceeding 0.05 mm from the designated centerline of the spring blade.
Elimination of Interface Micro-Gaps
Cross-sectional metallographic testing is performed every shift to verify complete metal-to-metal contact at the riveting interface, eliminating air pockets that accelerate localized thermal runaway.
Control of Edge Burrs and Stamping Stresses
Precision carbide progressive dies with strict clearance tolerances maintain burr heights below 0.02 mm, preventing debris accumulation inside sealed relay enclosures.
100% Automated Optical and Mechanical Sorting
Finished moving spring assemblies pass through high-resolution machine vision systems and pneumatic push-out load testers to guarantee zero defect leakage prior to export packaging.
