How do I wire the N/O and N/C contacts?
The three pins are COM (common), NO (normally open) and NC (normally closed). Connect your signal or load to COM. With the actuator released, COM is connected to NC; when pressed, COM connects to NO. Check the pin layout on the physical part before soldering.
Can I connect it to an Arduino or ESP32 digital input?
Yes. Wire COM to GND and the NO pin to a digital input with the internal pull-up enabled, so the input reads HIGH when open and LOW when pressed. Keep the switched voltage within its 5A / 250VAC rating and within your board's logic level (3.3 V on ESP32).
