Yueqing Tongda: Button Switch Drives Multi-Field Control

  In fields such as industrial control, household appliances, and security equipment, the Button Switch is a basic control component for realizing "one-click start-stop". Its operational stability and environmental resistance directly affect the operational safety of equipment. Yueqing Tongda Wired Electric Factory, which has been deeply engaged in the switch industry for more than 30 years, focuses on the R&D and manufacturing of Button Switches. It solves control pain points in different scenarios through technological innovation, provides highly adaptable button switch products for various industries, and has become an important force in promoting the localized application of button switches.

   Since its establishment in 1990, Yueqing Tongda has always built its product system based on "demand orientation". In the early days, it mainly focused on general-purpose switches. With the upgrading of industrial automation and the popularization of smart home appliances, the market demand for Button Switches with "durability, anti-misoperation, and multiple specifications" has become increasingly urgent. The factory quickly listed Button Switch as a core main product, set up a special R&D team, and after years of technological iteration, has formed a product matrix covering 1A-20A current and 12V-380V voltage. This matrix can meet the diverse control needs of equipment ranging from small household appliances to heavy industrial machinery.

   Technological innovation is the core competitiveness of Yueqing Tongda's Button Switches. Aiming at the pain points of traditional button switches, such as "short pressing life, vulnerability to environmental interference, and high risk of misoperation", the R&D team has carried out targeted optimizations: In terms of contact design, silver-nickel alloy material is used and treated with vacuum coating to reduce the contact oxidation rate, increasing the switch's pressing life to more than 150,000 times, far exceeding the industry's conventional standard of 100,000 times; In terms of protection performance, some products have reached IP67 protection level, which can work stably in environments with temperatures ranging from -30℃ to 90℃, as well as humid and dusty conditions.

   To meet the characteristics of segmented industries, the factory provides flexible customized services. For the industrial field, it has developed a "high-current model" that supports 16A high-current on-off, meeting the high-power control needs of motor start-up and other scenarios; For security equipment, it has launched a "luminous model" that uses a fluorescent material coating to enable quick operation in dark environments. Previously, the Button Switch customized for an industrial equipment enterprise, relying on its "shock resistance + anti-misoperation" features, helped reduce the failure rate of the enterprise's production line by 25% and secured a long-term cooperation order.

   Quality control runs through the entire production process of Button Switches. In the raw material link, copper materials and engineering plastics that meet RoHS standards are carefully selected, and each batch undergoes anti-aging and corrosion resistance tests; In the production link, fully automated stamping and assembly equipment is introduced to control the component size error within 0.01mm, avoiding performance deviations caused by manual operations; In the testing link, each switch must pass the "pressing life test, insulation resistance test, and high-low temperature cycle test" to ensure a 100% factory qualification rate. With strict quality control, the products have passed UL, VDE, and CQC certifications and become qualified suppliers for enterprises such as Midea and Gree.

   Facing the industry trend of "intelligence and low power consumption", Yueqing Tongda is accelerating the technological upgrading of Button Switches. On the R&D side, it is exploring the integration of wireless communication modules into button switches to realize the integration of "remote control + status feedback"; On the production side, it is promoting the construction of "digital workshops" and realizing real-time traceability of production data through the MES system, improving production efficiency by 18%. In the future, the factory will continue to take the Button Switch as the core, adhere to the concept of "precision manufacturing", provide more reliable and intelligent control components for global customers, and promote the innovative development of the button switch industry.
