As the benchmark model of Yueqing Tongda Wire Electric Factory's micro switch series, the High-Current Micro Switch for Household Blender features "high sensitivity, ultra-long lifespan, and multi-scenario adaptability" as its core advantages. Integrating the company's 35 years of switch manufacturing expertise, it has become a key control component in household appliances, automotive electronics, industrial automation, and other fields, thanks to its minimal contact gap and rapid action mechanism. Its performance and reliability have been certified by multiple authoritative organizations worldwide, securing its mainstream position in the niche market.
Micro Switch Introduction
The HK-14 series adopts a core design featuring 'silver alloy contacts with patented rapid-action mechanism.' The contacts are made of AgSnO₂ silver-tin oxide alloy material and undergo a vacuum coating process, with a contact resistance of ≤50mΩ, ensuring stable current transmission without attenuation and effectively preventing signal delays or poor contact caused by contact oxidation. The trigger response time is ≤5ms, and operating stroke deviation is controlled within ±0.05mm, with trigger sensitivity far exceeding industry standards. To meet different mechanical trigger requirements, the series offers a comprehensive range of actuator lever combinations, including 8 types of levers: short-arm, long-arm, roller (available in nylon or metal), button, fork, etc., precisely matching various conditions such as rotary mechanisms, linear motion devices, and push-type controls.
