Creality 3D întrerupător end-stop

Accurate homing and axis limit detection are critical for reliable 3D printing, yet worn or faulty end-stop switches can cause failed prints, layer shifts, or even mechanical damage. The Creality 3D End-Stop Switch is a mechanical limit switch engineered to provide precise and repeatable position feedback for the X, Y, and Z axes of your printer. With its lever arm and roller actuator, it ensures smooth triggering even with slight misalignments, while the normally closed (NC) configuration guarantees a fail-safe signal. Whether you are replacing a damaged switch or building a custom printer, this component restores the precision your machine demands.

Who is it for

This end-stop switch is ideal for owners of Creality Ender-3, Ender-3 Pro, Ender-5, CR-10, CR-10S, CR-20 series, and similar 3D printers that use mechanical limit switches. It is also suitable for DIY enthusiasts and makers who need a reliable limit switch for custom CNC or automation projects requiring a compact, durable, and easy-to-mount solution.

Tips

Before installing, ensure the printer is powered off and unplugged. Align the switch so that the roller contacts the moving part of the axis smoothly without excessive force. After replacement, re-home your printer and verify that each axis stops correctly. If the switch triggers too early or late, adjust its position slightly along the mounting slots. Keep a spare switch on hand to minimize downtime during long print jobs.
