Red Limit Switch Module – Mechanical Endstop Sensor in Relay and switches | Electro Boat

Red Limit Switch Module – Mechanical Endstop Sensor

This module mounts a microswitch with a roller lever that rolls across the contact surface rather than scraping it as a normal lever can. The output is normally pulled HIGH. When the beam is broken, the output is pulled LOW and a red LED on the module illuminates. The Red Limit Switch Module is a compact mechanical endstop switch used for detecting physical limits or positions in robotics, CNC machines, and 3D printers. It provides a digital output when triggered and is compatible with Arduino and other microcontrollers.

Detailed Description:

This Red Limit Switch Module is a mechanical lever-type switch mounted on a PCB, designed to act as an endstop detector or mechanical position sensor in motion control systems. When the lever is pressed, it changes the digital output state, allowing your microcontroller to take action—like stopping a motor, reversing direction, or triggering alerts.

With built-in resistor circuits and signal conditioning, it’s plug-and-play with Arduino, CNC drivers, 3D printers, and other logic-level systems. The compact design and pre-soldered pins make it easy to integrate into any automation or robotics platform.
