Yueqing, November 07, 2025 — Yueqing Tongda Wired Electric Factory, a veteran enterprise with 38 years of experience in switch manufacturing, recently announced that its classic LED Rocker Switch series has completed a comprehensive technical upgrade. Relying on a number of patented technologies authorized between 2024 and 2025, the upgraded products have achieved breakthroughs in performance stability, production precision, and scenario adaptability. Currently, they have received bulk additional orders from the smart home and commercial equipment sectors, demonstrating the market competitiveness of iterative upgrades for mature products.
It is understood that this upgrade is not the launch of a new product category, but a technical iteration based on the existing LED rocker switches. The core upgrade points focus on three major dimensions: In terms of contact performance, the enterprise's patented "silver layer - copper substrate - silver layer" composite silver contact structure is adopted. The gold-plated contact surface reduces the initial contact resistance from ≤8mΩ to ≤5mΩ, increases the rated load to 16A (250V AC), and enhances the arc erosion resistance during high-frequency switching by 40%; In the LED indicator system, the lamp bead packaging process is optimized, with the addition of a blue light option. The working voltage is expanded to 5V-36V to meet the high-voltage needs of industrial equipment, and the glare of the light-transmitting area is reduced by 60% after optical reconstruction; In terms of production technology, independently developed fully automated assembly equipment is introduced, reducing the key dimensional error from ±0.03mm to ±0.02mm and increasing assembly efficiency by 30%.
The upgraded LED rocker switches perform better in their existing advantageous scenarios. In the smart home sector, a leading brand reported that after equipping with the upgraded version, the repair rate of products due to switch failures dropped from 2.1% to 0.7%, and the user satisfaction with the LED status indicator reached 98%; In the commercial equipment sector, the customized version adapted to the new national standard coffee machines passed the 100,000-time press test without failures, and its service life was 50% longer than that of the old version; In the industrial auxiliary sector, the derivative model developed for the humid environment of workshops draws on the sealing technology of waterproof switches, increasing the insulation resistance to ≥100MΩ and further expanding its adaptability.
Strict quality control ensures the effectiveness of the upgrade. The upgraded version LED rocker switches continues the "three-level quality inspection system". The LED lamp beads undergo an additional high-low temperature aging test from -40℃ to 120℃, the contacts undergo a 16A full-load switching endurance test, and the qualification rate of finished products remains 100%. At present, the products have obtained CQC and CE certifications, and the UL certification is in the final stage. The annual production capacity has been increased to 18 million units, which can meet the incremental demand of domestic and foreign markets.
"Continuous iteration of mature products is our core strategy to respond to market demands," said the enterprise's technical director. This upgrade integrates 7 patented technologies, and the next step will be to develop a low-power version based on customer feedback to continuously strengthen product competitiveness.
