Classic Household Appliance Rocker Switch: Appliance-Specific, Steadily Empowering for Thirty Years

Yueqing, China, [December 3, 2025] — As a classic core component customized exclusively for household appliances by Yueqing Tongda Wired Electric Factory, the Household Appliance Rocker Switch remains the preferred switch component for refrigerators, washing machines, air conditioners and other household appliances, thanks to its more than thirty years of experience in adapting to appliance scenarios, strict reliability standards and precise load control capabilities. This product, deeply rooted in the internal control scenarios of household appliances, has become a long-term supporting partner of many well-known domestic and foreign home appliance brands with its core characteristics of "temperature and moisture resistance, precise adaptation and long-term durability".

Following the design concept of "appliance-specific", this household appliance rocker switch series of switches adopts a compact structural design. Its overall size is adapted to the narrow internal space of household appliances, supporting two installation methods: snap-on and welding. It does not occupy excessive internal layout space, perfectly meeting the assembly needs of household appliances such as washing machine control panels and refrigerator door interlocks. The rocker structure is optimized into a short-stroke design, with a trigger stroke of 0.8-1.2mm and an operating force of 2.0-3.5N, suitable for high-frequency pressing scenarios of household appliance buttons. The pressing feedback is crisp without stickiness or jamming.

Core performance directly addresses the pain points of household appliance use: The shell is made of high-temperature resistant PA66 reinforced nylon material (UL94 V-0 grade), with an operating temperature range of -20℃ to 90℃, which can withstand the heat dissipation high temperature and ambient low temperature during the operation of household appliances; The contacts are made of silver-palladium alloy material, processed by vacuum coating technology, with an initial contact resistance of ≤25mΩ. The rated load is precisely matched to the needs of household appliances, covering 3A/250V AC, 5A/125V AC and other gears, which can safely carry loads such as household appliance motors and heaters, effectively preventing contact oxidation and ablation. The product complies with the IEC 61058 household appliance switch standard, with an insulation resistance of ≥100MΩ and a terminal withstand voltage of 1500V AC, eliminating the risk of electric leakage in humid environments.

Durability and adaptability lead the industry: The mechanical lifespan exceeds 100,000 cycles, and the electrical lifespan reaches 60,000 cycles. Calculated at a daily operation frequency of 20 times for household appliances, it can run stably for more than 15 years, far exceeding the average service life of household appliances; It supports various contact configurations such as normally open (NO), normally closed (NC) and Single Pole Double Throw (SPDT), adapting to diverse control needs of household appliances such as power start-stop, function switching and safety interlocking. At the same time, it is compatible with the standardized design of household appliance PCB boards, simplifying the overall assembly process.

Decades of market verification have earned an excellent reputation: Supporting a leading white goods brand's washing machines as door interlock switches, the after-sales failure rate has remained below 0.2% for a long time; Adapting to the mode switching function of well-known air conditioning brands, the temperature resistance performance has passed 10 years of market testing without faults; Providing power switches for microwave ovens and rice cookers of small home appliance brands, the customer complaint rate has dropped by 80% after bulk application.

Relying on Yueqing Tongda's full-process quality control system, each household appliance rocker switch finished product must pass 6 core tests including on-off consistency, high-low temperature cycle and durability pressing, with a factory qualification rate of 100% and a stable annual production capacity of 5 million units. The person in charge of the enterprise stated that they will continue to optimize the product's load adaptation range and installation compatibility, retain the production line of classic models, provide stable and reliable core control components for the home appliance industry, and continue the long-term win-win cooperation with home appliance enterprises.
