Limit Switch

A control component that detects motion positions and limits the travel of equipment.

Widely used in machine tools, assembly lines, hoisting equipment, packaging machinery, automated manipulators, elevators, door and window systems, pneumatic and hydraulic equipment, and various industrial automation scenarios. 

As a core safety and positioning component for industrial equipment, it delivers stable and reliable performance across multiple applications. In CNC machine tools and processing equipment, it restricts the travel of tool posts and worktables to prevent over-travel collisions and ensure machining accuracy. Automated assembly lines and conveying systems rely on it for workpiece-in-position detection to enable sequential operations, sorting, and transfer. Hoisting equipment such as cranes, elevators, and lifts are equipped with limit switches for travel limits and end-position protection to eliminate safety hazards. It is also adapted for robotic arms, packaging machinery, automatic doors, hydraulic cylinders, and other devices, precisely controlling motion boundaries while supporting both equipment protection and automated operation.
