Micro Switch Introduction
As Leqing Tongda's classic switch designed for general use scenarios, the HK-04G focuses on 'high stability, wide compatibility, and cost-effectiveness,' integrating 35 years of manufacturing experience. It is suitable for smart homes, small industrial equipment, commercial appliances, and other scenarios, serving as a key circuit control component that balances reliability and cost.
Micro Switch Application
Equipped with an optimized micro quick-acting trigger mechanism, the actuation travel is precisely controlled between 0.15-0.3mm, with an operating force range of 1.2-3N. The pressing feel is light and the feedback is crisp, without any hysteresis or sticking, allowing for precise control with a 'light touch activation.' The contacts are made of high-purity silver alloy and undergo a precision plating process, with an initial contact resistance of ≤30mΩ. The rated load supports 0.1A/250V AC and 0.5A/125V AC, specifically designed for low-power electronic devices, effectively preventing contact failure caused by contact oxidation.
Small Industrial / Commercial: Suitable for conveyor equipment, coffee machines, and printers. Optimization of terminal structure improves assembly efficiency. Custom versions, after adjusting terminal spacing, increase installation efficiency by 25%.
