Black and White Base True Silver Point Mouse Switch

As the core micro switch developed by Yueqing Tongda for general-purpose precision control scenarios, the HK-20 series is positioned around 'compact design and fast, precise triggering.' With 38 years of experience in micro switch manufacturing, it combines sensitive response, long lifespan, and broad adaptability, making it a key component for circuit control in consumer electronics, industrial control, smart home devices, and more, providing reliable travel detection and functional on/off solutions for equipment.

Using a patented snap-action quick-trigger mechanism, the trigger response time is ≤8ms, improving performance by 25% compared to traditional micro switches. The trigger travel is precisely controlled between 0.3-1.0mm, with an operating force range of 1.5-4N. The pressing feedback is clear and crisp, without sticking or free play, allowing for precise control of 'light touch to connect, release to break,' perfectly suited for scenarios requiring high trigger sensitivity. The contacts are made of high-purity silver-tin alloy and processed with precise spot welding, with an initial contact resistance of ≤30mΩ. The rated load supports 1A/250V AC and 3A/125V AC, effectively preventing contact heating or burning when current passes through.

Adapts to function buttons and travel detection of portable printers, Bluetooth headsets, and smart wearable devices. Its miniature size perfectly matches the compact design of devices, and its sensitive activation enhances the user operation experience. After being applied by a well-known consumer electronics brand, the product's button failure repair rate dropped by 60%.

Used for travel limit control of small conveyor equipment and automation sensors, the quick-action triggering mechanism ensures precise coordination between mechanical motion and circuit switching. After being adopted by a certain machinery factory, equipment positioning errors were reduced to ±0.2mm, and production efficiency increased by 15%.
