Limit Switch Module / Micro Limit Switch:

 The Limit Switch Module is a compact and reliable mechanical switch used to detect motion limits, end positions, or object presence in a variety of electronic and mechanical systems. Designed for robotics, 3D printers, CNC machines, and automation projects, this switch ensures precision, safety, and consistent performance.

It’s widely used to prevent over-travel, trigger endstops, or control movement limits in linear actuators, robotic arms, and sliding mechanisms — making it an essential component for makers and engineers.

How It Works

When an object or mechanical part comes in contact with the lever or roller arm, the switch opens or closes its electrical contacts, changing the output signal.
This change is detected by the microcontroller, allowing it to stop movement, trigger safety actions, or record position feedback — a must-have for any motion control system.
