Mechanical Limit Switch Breakout Board

This device employs a standard miniature limit switch on a breakout board with a detachable JST connection cable included. Once the 3D printer/CNC frame axis reaches the end of the shaft as the motor slides down, the limit switch pushes up against the casing barrier and stops its motion. This is how the 3D printer/CNC machine knows when to stop and reverse direction in its plain.

Alternate applications include autonomous robot guidance, comes with all the components surface mounted for easy connection and LED to indicated when the axis is triggered. 


  • 3 Pin JST to female connector
  • Dimension: 1.57 x 0.63 in (4 x 1.6 x 0.9 cm)
  • Integrated LED for debugging.
