Thermal Rice Cooker Water Heater Juicer Micro Switch

The HK-04G-L micro switch features a short-lever trigger structure and a snap-action mechanism, allowing rapid circuit switching with minimal mechanical force. With its precise operating characteristics, broad environmental adaptability, and international safety certifications, it is widely applied in key control scenarios such as home appliance management, industrial automation, and electronic devices, serving as a critical component for ensuring safe operation and precise control of equipment.

As a trusted supplier to renowned brands like LG, Whirlpool, and Supor, Yueqing Tongda has a mature R&D and quality control system, offering customized services for the HK-04G-L (such as lever length and terminal type adjustments), along with comprehensive pre-sales technical support and after-sales warranty services, ensuring optimal compatibility between the product and customer equipment.

Features high-sensitivity operational performance. It utilizes a precision spring energy storage structure, whereby the triggering response is independent of the applied force rate. The operating force required is only 1.0–3.5 N, with a pre-travel controlled within 0.3–1.0 mm, allowing the capture of minute displacement signals suitable for precise detection requirements. The action differential is ≤0.4 mm, ensuring instantaneous and accurate contact switching.

Operating temperature range: -25℃ to 125℃, capable of withstanding 3D vibration shocks at 10–55Hz with 1.5mm amplitude (lasting 1 hour), insulation resistance ≥100MΩ (500VDC), dielectric voltage between terminals and metal casing up to 1500V/0.5mA/60s, suitable for industrial scenarios with high temperatures and multiple vibrations.

Fully certified by internationally and domestically recognized authorities such as UL, CUL (CSA), VDE, ENEC, and CQC, and compliant with the ISO 9001 quality management system standard, the product can be directly adapted to meet regulatory requirements in North America, Europe, and China.
