Product Overview
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 reject the "one-size-fits-all" standardized production model and instead focus on customer needs, providing comprehensive customization services to ensure a perfect fit between the rivets and the internal structure of the circuit breaker.
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 customer-provided drawings or samples, with errors controlled within ±0.01mm, effectively avoiding installation jams and loose connections caused by dimensional deviations.
For circuit breakers with special structures, we can also customize different structural types such as stepped rivets, semi-hollow rivets, and solid rivets to meet diverse functional requirements such as conductive connections, insulation fixation, and component fastening.

Structural Types
Stepped / Semi-Hollow / Solid
In terms of material selection, considering the working environment of the circuit breaker, we offer a variety of base materials such as copper, copper alloy, stainless steel, and iron, and can perform surface treatments such as silver plating, tin plating, and zinc plating according to conductivity requirements. For example, the rivets used in the conductive circuit of the circuit breaker are made of high-purity copper and silver-plated, which increases conductivity by more than 30%; the rivets used for fixing the casing are made of highly corrosion-resistant 304 stainless steel, extending the service life of the equipment.
Product Features
The safety performance of miniature circuit breakers is directly related to electrical safety, which requires rivets to possess excellent overall performance. Through advanced manufacturing processes and strict quality control, we endow our products with three core advantages:
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 can be formed. Even in the vibration environment of long-term operation of circuit breakers, the connection can still be kept tight, eliminating hidden dangers of poor contact, overheating, and fire caused by loosening.
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 can still maintain stable mechanical and electrical properties in extreme environments such as high temperature, humidity, and dust, making it suitable for various scenarios such as homes, industrial plants, and commercial complexes.
Frequently Asked Questions
Q
What size range of rivets can you customize for miniature circuit breakers?
We offer full customization with shank diameters ranging from 0.8mm to 5mm and lengths from 1mm to 10mm. All dimensions are precisely machined according to customer-provided drawings or samples, with tolerances controlled within ±0.01mm.
Q
What materials are available for circuit breaker rivets?
We offer a variety of base materials including copper, copper alloy, stainless steel (304), and iron. Surface treatments such as silver plating, tin plating, and zinc plating are also available depending on conductivity and corrosion resistance requirements.
Q
How does silver plating improve the performance of conductive rivets?
Rivets used in the conductive circuit of circuit breakers are made of high-purity copper and silver-plated. This surface treatment increases conductivity by more than 30%, ensuring reliable electrical performance and reducing resistance-related heat generation.
Q
What structural types of rivets can be produced for special circuit breaker designs?
For circuit breakers with special internal structures, we can produce stepped rivets, semi-hollow rivets, and solid rivets. Each type is designed to meet specific functional requirements such as conductive connections, insulation fixation, and component fastening.
Q
What environmental conditions can these rivets withstand?
Our rivets are tested under high and low temperature conditions (-40℃ to 120℃), aging resistance tests, and salt spray tests. They maintain stable mechanical and electrical properties in extreme environments including high temperature, humidity, and dust — suitable for residential, industrial, and commercial applications.
Q
How do you ensure the rivets remain tight during long-term circuit breaker operation?
We use a cold forging process that enables rivet rod strength to reach grade 4.8 or above. After pressing and riveting, the resulting connection structure remains stable even under prolonged vibration, eliminating risks of loosening, poor contact, overheating, or fire hazards.
