Endstop Mechanical Limit Switch – Precision Positioning for 3D Printers, CNC and Arduino Projects

Reliable and Durable Switch with 3-Pin Connector for Homing and Over-Travel Protection

This mechanical limit switch (Endstop) is a crucial component for ensuring the safety and precision of your 3D printer, CNC machine, or robotic system. It provides reliable detection of end positions and serves as a homing sensor for the X, Y, and Z axes, preventing your equipment from mechanical damage caused by over-travel.

Why Choose This Mechanical Endstop Switch?

• Reliable & Precise Operation: The mechanical contact provides a stable and accurate trigger signal, ensuring consistent recognition by mainboards like RAMPS 1.4.

• Robust & Long-lasting Build: Featuring a metal lever actuator and housing, this switch is far more durable and impact-resistant than common plastic models. The lever can be slightly bent for perfect positioning.

• Wide Compatibility & Easy Installation: Equipped with a standard 3-pin connector (VCC, GND, Signal), it plugs directly into control boards such as RAMPS 1.4, Arduino, MKS, and others. It operates at 5V and is easily mounted using the integrated screw holes.

• Clear Visual Indication: The built-in LED indicator lights up when triggered, making setup calibration and troubleshooting significantly easier.

Technical Specifications:

• Type: Mechanical Limit Switch, Normally Open (NO)

• Operating Voltage: 5V DC (supports 3V to 12V)

• Connector: 3-pin dupont cable (VCC, GND, OUT)

• Output Signal: High (normal), Low (triggered)

• Actuator: Durable metal lever

• Dimensions: Approx. 35.5 x 22.0 x 6.1 mm

• Mounting: 2 x M3 screw holes

Ideal for Use With:

• 3D Printers: For homing and defining the maximum travel limits of each axis.

• CNC & Milling Machines: For positioning and limiting the working area.

• Robotics & Automation: As an end-position sensor in linear motion systems.

• Educational & DIY Projects based on Arduino.
