Limit Switch: General-Purpose Device for Motion Position and Stroke Control

Limit Switch: General-Purpose Device for Motion Position and Stroke Control

The limit switch is a general term for switches used to restrict object motion positions or strokes, including travel limit switches, crane limit switches, micro limit switches, etc. It detects mechanical motion through contact or non-contact methods, triggering circuit changes at preset positions to control equipment operation or stop motion. Widely used in industrial automation, transportation, and construction machinery, this versatile switch is a fundamental component for ensuring safe and regulated motion in mechanical systems.
