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 precision electronics and medical devices. For example:
Printer: A swing arm in the paper feed channel detects the edge of the paper. A 0.3mm pre-travel can identify thermal paper with a thickness of 50μm;
Medical monitor: Button activation uses a short swing arm structure, with an operating force of 1.0N balancing trigger sensitivity and prevention of accidental activation;
Smart terminal: Battery compartment cover closure detection, with an over-travel ≥0.2mm to ensure the cover is fully secured.
