Push Switch: Yueqing Tongda's Core for Multi-Scenario Control Solutions

   In fields such as industrial equipment, household appliances, and medical instruments, Push Switch (button switch) is the core component for realizing "one-click control", and its reliability and adaptability directly affect equipment operation efficiency. Yueqing Tongda Wired Electric Factory, which has been deeply engaged in the switch industry for more than 30 years, provides customized control solutions for various industries through its dedicated R&D and precision manufacturing of Push Switch, becoming an important force in promoting the localization upgrading of button switches.

   Since its establishment in 1990, Yueqing Tongda has always been guided by the principle of "scenario needs driving product innovation", gradually expanding from basic button switches in the early days to multi-functional composite products. With the accelerating trend of equipment miniaturization and intelligence, the market demand for Push Switches with "small size, long service life, and anti-misoperation" has surged. The factory quickly listed it as a core main product and set up a special R&D team to tackle key problems. After years of technical accumulation, it has formed a Push Switch product system covering 1A-10A current and 3V-250V voltage, which can adapt to the diverse control needs from micro household appliances to heavy industrial equipment.

   Technological breakthrough is the core competitiveness of Yueqing Tongda's Push Switch. Aiming at the pain points of traditional button switches such as "pressing jamming, short service life, and easy water ingress", the R&D team has carried out targeted optimizations: in terms of contact design, silver-copper composite material is adopted, which is processed by vacuum welding technology to reduce contact resistance, increasing the electrical service life of the switch to more than 100,000 times; in terms of structure, an innovative "dust-proof and waterproof sealing ring" is used, and some products have reached IP65 protection level, which can be used stably in humid and dusty environments such as kitchens and workshops.

   To adapt to different industry scenarios, the factory provides flexible customized services. For the home appliance industry, it has developed "Push Switch with Light", which uses LED indicator lights to feedback the on-off status of equipment in real time; for the industrial field, it has launched "anti-misoperation model", adding a raised pressing panel to avoid equipment shutdown caused by accidental touch; for medical equipment, it uses medical-grade environmentally friendly plastic shells, which have passed biocompatibility tests to ensure safe use. Previously, the washing machine-specific Push Switch customized for a well-known home appliance enterprise, relying on "mute pressing + waterproof design", helped reduce the product failure rate by 30% after its launch.

   Quality control runs through the entire production process of Push Switch. In the raw material link, copper materials and plastics that meet RoHS standards are carefully selected, and each batch undergoes component testing; in the production link, a fully automated assembly line is introduced to control the component assembly error within 0.01mm, avoiding deviations caused by manual operations; in the testing link, each switch must pass "pressing life test", "temperature resistance test", and "insulation performance test". Among them, the life test simulates actual use scenarios, and only after 100,000 consecutive presses without failure can the switch leave the factory. 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 technological upgrading. On the R&D side, it is exploring the integration of NFC (Near Field Communication) technology into Push Switch to realize the integration of "touch control + data transmission"; on the production side, it is promoting the construction of "digital workshop", realizing full-process traceability through MES system and improving production efficiency by 20%. In the future, the factory will continue to take Push 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.
