Yueqing Tongda Wired Electric Factory: With Led Rocker Switch as the Core, Illuminating a New Track for Smart Switches

   Currently, as the demand for integrated control and status display in electrical equipment continues to grow, the Led Rocker Switch (LED-equipped rocker switch), with its dual functions of "control + indication", has become a key component in the fields of home appliances, industrial equipment, and automotive electronics. Yueqing Tongda Wired Electric Factory, which has been deeply engaged in the switch industry for more than 30 years, leads the smart switch track through its dedicated R&D and precision manufacturing of this product, delivering high-quality products that combine practicality and aesthetics.

   Since its establishment in 1990, Yueqing Tongda Wired Electric Factory has always been guided by the principle of "technological iteration keeping up with market demand", expanding from basic rocker switches to multi-functional composite products. With the intelligent upgrading of equipment, the demand for "switch status visualization" has become urgent. The Led Rocker Switch, which can display on-off status and faults in real time, has been designated as a core main product for R&D. After more than a decade of refinement, the factory has formed a product matrix covering multiple scenarios and specifications, and has become one of the few enterprises in the industry capable of providing integrated solutions for "LED integration, brightness adjustment, and water-dust resistance".

   Technological innovation is its core competitiveness. The R&D team has made breakthroughs to address the pain points of traditional LED-equipped switches, such as "uneven brightness, easy burnout of LEDs, and high energy consumption": high-brightness and low-power SMD LEDs are selected for the lamp beads, combined with an independent optical light-guiding structure to ensure uniform light without dark areas; the circuit design optimizes current-limiting resistors to control the LED current within a safe range, reducing standby power consumption by more than 30% compared with traditional products; for humid and dusty scenarios, the LED module and the switch body are sealed as an integrated unit, and some products have reached IP65 protection level, suitable for kitchen appliances and outdoor equipment.

   In terms of product adaptability, it fully meets the customized needs of the industry. In terms of appearance, colors such as black, white, and silver are available; in terms of specifications, it covers pole numbers of 1P and 2P, with a rated voltage of 12V-250V, suitable for voltage scenarios in multiple fields. Previously, the special refrigerator model customized for a well-known home appliance enterprise used soft blue LED to indicate the cooling status, balancing user experience and practicality, and has been highly recognized since its launch.

   Quality control is the "lifeline" of the enterprise. In the raw material link, core components such as LED beads and copper contacts are carefully selected, and only suppliers with RoHS certification are cooperated with; fully automated SMT equipment and laser welding are introduced in production to ensure stable connection between LEDs and switches; in the testing link, each batch of products must undergo four major tests: "brightness consistency, 100,000-cycle mechanical life, high-low temperature cycle, and electrical performance", with the brightness deviation controlled within 5%. Relying on strict quality control, the products have passed UL, VDE, and CQC certifications and become qualified suppliers for Midea, Haier, and BYD.

   Today, the factory's Led Rocker Switches are widely used: in the home appliance field, they are the core control components for ovens and dishwashers; in the industrial field, they provide operation switches for CNC machine tools and distribution boxes; in the automotive electronics field, they are suitable for car refrigerators and ambient lights; in the smart home field, they are combined with control panels to realize the integration of "light control + status feedback". The products cover more than 30 provinces and cities in China and are exported to Europe, Southeast Asia, and South America. In 2024, the sales volume increased by 25% year-on-year, becoming a pillar of revenue. Customers have reported that after use, the operational convenience and safety of the equipment have been improved, and the after-sales maintenance rate has decreased by nearly 40%.

   Facing the trend of "miniaturization, low power consumption, and the Internet of Everything" in smart equipment, the factory is accelerating technological upgrading. On the R&D side, it has launched the "Miniaturized Led Rocker Switch" project, planning to reduce the assembly size by 30% to adapt to wearable devices; it is also exploring the combination of Bluetooth modules with LEDs to realize remote monitoring. On the production side, it is promoting the construction of "smart manufacturing workshops" and introducing MES systems to realize full-process traceability and improve efficiency and quality.

   In the future, Yueqing Tongda Wired Electric Factory will continue to take the Led Rocker Switch as its core, adhere to the concept of "technological innovation + quality first", break through industry bottlenecks, provide more intelligent, reliable, and energy-efficient solutions for global customers, and lead the development of the industry.
