Product Details
3 Pin Momentary Roller Lever Arm Micro Limit Switch AC 250V 5A SPDT
A roller-lever micro limit switch with SPDT contacts for endstop and interlock sensing. This listing is for the switch only.
What it does
- Momentary roller-lever actuation for mechanical position detection.
- SPDT contacts support normally-open or normally-closed wiring.
- Three terminals for common, NO, and NC connections.
- Suitable as a motion endstop or safety interlock sensor in DIY machines.
Compatibility and setup
- For MCU inputs, use the switch to pull a GPIO with a resistor; do not feed mains into a microcontroller.
- Mains switching requires correct insulation, fusing, and enclosure—follow electrical codes.
- Mount so the roller actuates cleanly without side-loading the lever beyond its travel.
- Debounce in firmware for digital inputs.
Applications
- 3D printer and CNC endstops
- DIY automation interlocks
- Robotics limit detection
- STEM electromechanical labs
Package includes
- 1 × roller-lever micro limit switch (SPDT)
Confirm terminal labels (COM/NO/NC) on your unit. Ratings are listed in the Specifications section when present.
