Micro switch with roller lever, 3 terminals (COM/NO/NC). Go-to part for limit switching and position detection in robotics, 3D printers, CNC, and DIY automation.
Roller lever triggers smoothly against moving parts. Wire COM + NO to activate only when pressed, or COM + NC for fail-safe endstop behavior.
Specs
| Switch type | Micro switch, snap-action with roller lever |
| Terminals | 3: COM / NO / NC |
| Operation | Momentary (returns when released) |
| Typical use | Limit switch / endstop / position detection |
For microcontroller inputs, pair with pull-up/pull-down resistors or enable internal pull-ups for stable reads. Switching mains AC or high current? Check the printed rating and use proper enclosures.
