Use a 2-core cable to wire up our regular microswitches
| IMPORTANT WARNING: Note: Incorrect wiring can short V+ to GND causing damage to your controller: Double check wiring before powering on. We recommend using 2-core wiring only for this type of switch to avoid accidentally shorting V+. Only connect SIG and GND pins on the BlackBox. |
If you need a more EMI proof solution, consider upgrading to OpenBuilds Xtension Limit Switches
