Miniature circuit breakers come in a wide variety of models and specifications, resulting in significant differences in the size, material, and performance requirements of the rivets. We focus on customer needs, providing comprehensive customization services to ensure a perfect fit between the rivets and the internal structure of the circuit breaker.

Regarding size customization, rivet shank diameters range from 0.8mm to 5mm, and lengths from 1mm to 10mm. All sizes can be precisely machined according to drawings or samples, with errors controlled within ±0.01mm, effectively avoiding installation jams and loose connections. For circuit breakers with special structures, we can also customize different structural types such as stepped rivets, semi-hollow rivets, and solid rivets.

In terms of material selection, considering the working environment of the circuit breaker, we offer a variety of base materials and surface treatment options:

• High-Strength Connection — Vibration-Resistant & Anti-Loosening The cold forging process is adopted, and the strength of the rivet rod can reach grade 4.8 or above. After pressing and riveting, a stable connection structure is formed. Even in vibration environments, the connection remains tight, eliminating hidden dangers of poor contact or overheating.
• Stable Performance — Adaptability to Extreme Environments After passing multiple rounds of rigorous testing — including high and low temperature tests (−40℃ to 120℃), aging resistance tests, and salt spray tests — the product maintains stable mechanical and electrical properties in high temperature, humidity, and dust.
