Against the backdrop of continuous upgrades in low-voltage electrical appliances and precision control systems, Brass Stamping Switch Terminal Accessories have gradually become an important process route in the manufacturing of electrical contact components. This technology, by completing terminal forming and contact assembly in a continuous mold, not only shortens the process chain but also significantly improves dimensional consistency and contact reliability. It is widely used in relay static terminals, wall switch accessories, and related modular components, with its core objectives being high conductivity and long-term stable service capability.
From a materials perspective, brass is considered an ideal substrate for switch contact terminals due to its excellent conductivity, mechanical strength, and corrosion resistance. Common grades used in engineering applications include H65 and H70, which can be controlled through cold rolling and heat treatment processes to cover various electrical loads and structural strength requirements. In the industry knowledge system, this type of material often supports typical structural forms such as Electrical Terminal Brass blocks riveted with silver contact and Switch Parts riveted with silver contact.
For general conductive applications, high-precision brass strips such as CuZn30 and CuZn37 can be selected, with an electrical conductivity of not less than 28% IACS and an elongation of over 15%, balancing conductivity and plastic deformation requirements. When applications require higher strength, soft, semi-hard, or hard brass is used to achieve a tensile strength range of 250–600 MPa to adapt to load-bearing terminal designs such as Relay Pin Brass Terminals.
In terms of manufacturing processes, precision stamping is the core technology of the Brass Stamping Terminal. Continuous die stamping can complete multiple processes such as punching, bending, and stretching in a single die stroke, achieving a production cycle of 200–400 times per minute, making the mass production of Electrical Brass Metal Stamping for Socket Switches more efficient and stable. To maintain geometric accuracy during high-speed operation, the industry commonly employs micro-gap concealment technology, controlling the die gap to 5%–8% of the material thickness, ensuring a sheared bright zone ratio of over 80%, thereby effectively reducing the impact of burrs on contact performance. Simultaneously, high-precision progressive dies, under proper maintenance, can achieve a service life exceeding 30 million cycles, controlling critical dimensional tolerances within ±0.02 mm, providing a stable foundation for the long-term supply of Electrical Brass Press Parts for Switch Sockets.
The value of in-die riveting technology lies not only in improved efficiency but also in its indirect enhancement of electrical performance. By simultaneously bonding the terminals and contacts during the stamping process, positioning errors caused by traditional multi-station switching can be significantly reduced, ensuring a highly concentric and tightly fitted riveting interface for Silver Contact Points with brass terminals. This technological advantage is particularly prominent in applications of Electrical Contact Assemblies Brass Stamped Parts, helping to control contact resistance fluctuations and extending the service life of the entire assembly under high-frequency switching conditions.
Currently, in-mold riveting technology for brass is widely used in the low-voltage electrical appliance field, primarily for Electrical Contacts with Silver Contact. It is applied to core components such as stationary terminals of switches and relays, wall switch accessories, and socket accessories. Custom Brass Stamping with Silver Contact is the most widely used, allowing for customized stamping dimensions and riveting precision according to end-product requirements, further expanding the technology's application boundaries.
In switch manufacturing, Stamping Riveting Electrical Brass Press Parts provides a strong connection and stable conductivity, effectively preventing issues like loose contacts and poor contact during long-term use, meeting the needs of household and industrial switches. In relay manufacturing, this technology enables precise riveting of miniaturized contact components, aligning with the trend towards miniaturization and high reliability in relays, ensuring stable relay operation. In socket manufacturing, Custom Brass Stamping with Silver Contact offers wear resistance and oxidation resistance, improving socket lifespan and safety.
Brass in-mold riveting technology, a core technology in the precision manufacturing of low-voltage electrical appliances, is deeply intertwined with industry upgrades. Through scientific material optimization and efficient, precise stamping technology, this technology not only solves the pain points of traditional processing techniques but also promotes the improvement of low-voltage electrical appliance product quality, injecting new momentum into the industry's high-quality development. Switch parts riveted with silver contact, as a core application product of this technology, will continue to leverage its advantages, helping the low-voltage electrical appliance industry move towards a higher level.
