What are the key elements of the complete manufacturing process for a Riveted Contact Terminal Assembly?

Mass production of microswitches begins with metal stamping. Various conductive structural materials adhere to clear selection standards. Springs utilize copper alloys with a thickness of 0.1 to 0.3 mm, while contacts rely on silver alloys to ensure conductivity and arc resistance. High-precision imported stamping equipment, coupled with customized molds, can control component dimensional errors to within 0.01 mm. Multi-station molds can simultaneously complete multiple processes, such as blanking and bending. Finished stamped parts are then individually inspected for cracks and burrs, laying a solid foundation for the subsequent Riveted Contact Terminal Assembly.

Riveting is the core process for the stable connection of components. Axial pressure deformation of rivets achieves rigid fixation of parts, avoiding the high-temperature deformation problems caused by welding. Various riveting equipment, including manual, rotary, and hydraulic riveting, is available on the market to suit different production batches and product strength requirements. During production, precise control of riveting pressure is crucial to prevent spring deformation or loosening of connections. After completion, stroke and stress parameters are verified. Floating riveting technology is used to optimize assembly deviations, ensuring the assembly accuracy and operational stability of the Silver Alloy Contact Riveting Parts.

The plastic shell is formed using injection molding. PBT and glass fiber modified PA66 are the mainstream materials, possessing inherent flame-retardant and high-temperature resistant properties to meet switch insulation protection requirements. Raw materials are melted at high temperatures and injected into a mold for cooling and molding. High-end injection molding equipment can control shell tolerances to within 0.03 mm. Waterproof products use low-pressure injection molding, while special products use two-color injection molding to optimize the user experience. The well-defined shell structure accurately encapsulates internal components, securely housing the Electrical Contact Riveting Assembly and forming a basic protective framework.

The automated assembly process integrates all components. Automated production lines rely on robotic arms to place internal components, assemble springs and drive rods, seal the upper and lower shells using ultrasonic welding, and finally fix the external terminals. To achieve a high standard of protection, the assembly process incorporates sealing rings and labyrinth sealing grooves, along with a potting structure to seal gaps. All components are assembled systematically according to the established procedures, completely encapsulating the In-Die Riveted Moving Contact Assembly and transforming disparate parts into a fully functional microswitch.

Before leaving the factory, the finished product undergoes comprehensive performance testing. Electrical testing verifies contact conductivity, mechanical testing calibrates switch trigger force and stroke parameters, durability testing continuously simulates millions of switching operations, and environmental testing, including high and low temperature alternation, salt spray, and vibration, simulates complex operating conditions. Protection testing verifies sealing capabilities through deep water immersion. This multi-layered screening process thoroughly checks for potential component defects and comprehensively examines the long-term reliability of the Electrical Contact Assembly, selecting qualified products for the end-market.
