What is the Movable Contact Rivet?
Engineered for high‑frequency electrical switching and reliable circuit break performance, our Movable Contact Rivets are produced via advanced cold‑heading and composite cladding technologies. Designed specifically for integration into moving leaf springs within relays, contactors, and circuit breakers, these components deliver optimal mechanical strength alongside superior resistance to electrical arc erosion. Operating as a direct source manufacturer based in China, we control the entire metallurgical bonding process from precious metal wire drawing to precision rivet head formation. Our production lines utilize automated optical sorting systems to ensure zero-defect delivery for high‑volume industrial and automotive supply chains.
competitive advantage of Moving Contact
Anti‑fatigue rivet‑shank structure
Optimized cold‑heading forming improves shank mechanical strength, resisting cyclic shear stress from leaf‑spring vibration.
Collision‑resistant contact face
Silver‑alloy grade tuned to sustain repeated mechanical impact together with arc ablation for moving‑side working conditions.
Rivet‑shank dimensional consistency
For Moving Contact, strict tolerance for shank outer‑diameter, guaranteeing stable riveting interference fit onto relay leaf‑spring hole.
Stable electrical performance under movement
For Moving Silver Contact, maintain reliable contact status after thousands of mechanical collision cycles.
Technical Specifications & Materials of Moving Contact Rivets

Material Selection Guidance for Moving Silver Contact
AgSnO2 vs AgNi Selection Logic
AgSnO2 is optimized for DC inductive loads and heavy‑duty contactors due to supreme anti‑welding properties, whereas AgNi is preferred for AC resistive loads with high switching frequencies.
Base Metal Optimization
For Bimetal Silver Contact Point, choose oxygen‑free copper shanks for maximum thermal and electrical transfer.
Precious Metal Thickness Ratio
For Bimetal Rivet Contacts, selecting the correct silver crown thickness (0.3 mm to 1.2 mm) ensures the component achieves its rated electrical endurance lifecycle without premature core exposure.
Application Boundary & Typical End-Devices
| Latching Relays | Moving Contacts can be incorporated into relay moving-contact assemblies where the contact must follow the movement of a spring member during circuit switching. |
| Smart Meter Relays | For smart-meter relay assemblies, the contact system must accommodate repeated switching while maintaining the required electrical interface between the movable and fixed contacts. |
| Low-Voltage Switchgear | The component can be used in Moving Silver Contact assemblies for low-voltage electrical devices where a riveted contact is integrated with a spring or stamped conductive member. |
