The materials for electronic contact pieces can be selected from different metals or alloys according to specific application requirements. Common electronic contact piece materials include copper, silver, stainless steel, etc.
Copper is a commonly used electrical contact material because it has good conductivity and thermal stability. Silver has excellent conductivity and is suitable for low voltage and low current applications. Stainless steel has good corrosion resistance and is suitable for harsh environments such as high humidity and salt spray.
In addition, according to specific needs, alloy electrical contact pieces can also be selected, such as iron nickel alloy, nickel chromium alloy, etc. These alloy materials have high conductivity, high thermal diffusion rate, good corrosion resistance, and mechanical strength.
In general, when selecting materials for electronic contact pieces, it is necessary to consider their conductivity, corrosion resistance, wear resistance, high-temperature stability, and other characteristics to ensure that the electrical contact pieces can work normally in various environments.
Electrical Switches Contacts have the following features:
Good conductivity: it can conduct current efficiently, ensure the current passes through the switch smoothly when it is connected, and reduce the energy loss caused by the resistance.
Arc resistance: at the moment when the switch is opened and closed, arc may occur. High-quality electrical switch contacts have good arc resistance performance, reduce the ablation of arc to contacts and prolong the service life.
Low contact resistance: help reduce heating and improve working efficiency and stability of switch.
Wear resistance: in frequent switching operation, the contact shall be subject to friction, and good wear resistance can ensure long-term reliable operation.
Oxidation and corrosion resistance: resist oxidation and corrosion in the environment and maintain good conductivity.
Thermal stability: keep the physical and chemical properties stable under the heat generated when the current passes through.
Electrical switch contacts are used in many fields, such as:
In home circuit, the contact of lighting switch and socket switch determines the on-off reliability of circuit.
In the industrial control system, the contacts of various large electrical switches guarantee the normal operation and safety control of the equipment.
In the automotive electrical system, the contacts of window lifting switch, ignition switch, etc. play a key role in the realization of vehicle functions.
In the automatic production line of the plant, high-precision electrical switch contacts accurately control the start and stop of the machine; In the smart home system, stable switch contacts provide users with convenient lighting and electrical control experience.
As a professional manufacturer of metal stamping parts for electrical switch contacts, we always adhere to the mission of “craftsmanship stamping, intelligent electrical connection” and deeply cultivate the field of power connections. We are well aware that the performance of electrical switch contacts, as the core hub for current conduction and interruption, directly affects the safety and stability of equipment operation. To this end, we deeply integrate innovative technology with exquisite craftsmanship, committed to providing customers with high-precision and high reliability metal stamping products.
During the product development and design phase, our engineering team conducts in-depth research on the working principles and performance requirements of various electrical switches. We optimize the load characteristics, opening and closing frequency, and environmental adaptability of switch contacts in different application scenarios from multiple dimensions such as material selection, structural design, and surface treatment. Through extensive mechanical analysis and simulation, accurately design the shape, size, and tolerance of stamped parts to ensure a tight fit of contacts when closed and reduce contact resistance; Fast and reliable in breaking, reducing arc generation. At the same time, we are constantly exploring new alloy materials and composite materials to enhance the wear resistance and fatigue resistance of stamped parts while improving their electrical conductivity.
During the manufacturing process, we have developed an intelligent and high-precision stamping production line. Introducing internationally leading CNC stamping equipment and multi station progressive molds, combined with automated feeding and testing systems, to achieve precision machining throughout the entire process from raw materials to finished products. We strictly control every stamping process, using advanced mold cooling and lubrication technology to ensure that the metal sheet does not deform or have burrs during the forming process, and the product size accuracy is controlled at the micrometer level. In addition, we have developed exclusive surface treatment processes for different metal materials, such as nickel plating, silver plating, gold plating, etc., effectively improving the oxidation and corrosion resistance of stamped parts and extending the service life of electrical switches.
Quality control is the core of our production system. We have established a quality traceability system that covers the entire process, from component analysis and mechanical performance testing of raw materials entering the factory, to online size monitoring and appearance inspection during the production process, to electrical performance testing and life testing of finished products, every link is executed with strict standards. We are equipped with a professional testing laboratory that uses high-end equipment such as contact resistance testers, microhardness testers, and salt spray test chambers to comprehensively test the various properties of metal stamping parts. Only products that have passed all rigorous tests are allowed to be delivered to customers.
With excellent product quality and a comprehensive service system, our electrical switch contact metal stamping parts have been widely used in multiple fields such as smart homes, industrial automation, new energy vehicles, and power equipment. Whether providing stable power connections for smart sockets or ensuring reliable circuit continuity in industrial control cabinets, our products have won the trust of customers with outstanding performance. In the future, we will continue to increase our research and innovation efforts, continuously optimize production processes, and meet the growing market demand with higher quality metal stamping products, injecting new impetus into the development of the electrical industry.
