Micro Switch Introduction
The HK-04G-L micro switch features a short lever trigger structure and a snap-action mechanism, enabling rapid circuit switching with minimal mechanical force. With its precise operating characteristics, wide environmental adaptability, and global safety certifications, the product is widely used in critical control scenarios across home appliance control, industrial automation, and electronic equipment. It serves as a core component to ensure safe operation and accurate control of devices.
Micro Switch Application
Suitable for industrial automation limit detection.
For valve control: installed at the end of the butterfly valve stem. When the valve rotates to the 90° fully open position, the lever is pushed to switch the circuit, providing a position feedback signal;
Conveyor belts: fixed at the end of the conveyor track. When materials reach it, the switch is triggered to control the motor stop, and it can withstand vibrations of 10–50Hz generated by conveyor operation;
Machine tools: used as an emergency stop triggering component, designed with an operating force of 3.5N to meet the requirement for quick pressing in emergency situations.
