Endstop Mechanical Limit Switch

The Mechanical Endstop Limit Switch is a simple and efficient motion detection solution used in CNC machines and 3D printers to determine minimum and maximum axis positions. Instead of using optical sensors or complex interruption systems, this module relies on a mechanical lever switch that activates when the moving stage reaches the predefined position. When triggered, the switch pulls the signal line to LOW, allowing the controller board to accurately detect the limit position. An onboard LED indicator lights up during activation, providing clear visual feedback for easier testing and troubleshooting. The module includes a cable with a standard connector for quick installation and seamless compatibility with RepRap electronics , RAMPS 1.4 , and other popular controller boards. Designed for durability, the switch supports up to 1 million operations , making it a dependable choice for long-term motion control applications.
