DIYables Vertical Mechanical Limit Switch Module with 3 Pin XH2.54 Cable for Arduino ESP32 ESP8266 Raspberry Pi, Normally Open
Click to zoom
Quick Overview
This DIYables vertical mechanical limit switch module features a normally open (NO) configuration with a compact vertical design for precise position detection and motion control. It includes a 3-pin XH2.54 connector with a 1-meter cable for quick plug-and-play connection, eliminating complicated wiring. A built-in trigger indicator LED shows switch activation status at a glance, making testing and debugging straightforward.
The module outputs a digital signal directly readable by microcontroller GPIO pins and operates with both 3.3V and 5V logic levels. Its small, lightweight form factor makes it easy to mount in tight spaces on machines, enclosures, or chassis. Three clearly labeled pins — VCC, GND, and Signal — make wiring intuitive for all experience levels.
Ideal for 3D printers, CNC machines, robotics, and industrial automation projects requiring reliable end-stop or position sensing. Compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and any microcontroller platform with a digital GPIO input.
