🔧 Wiring guide
- Use a multimeter’s continuity mode to identify the centre pin, outer ground and switched contact.
- Choose the polarity for your circuit. Centre-positive wiring is common, but the connector does not enforce it.
- Solder the wires to the corresponding pins.
- Insulate the connections carefully to prevent short circuits.
- Insert the matching male plug, then check voltage and polarity before connecting your circuit.
⚠️ Never identify the pins from their physical position alone: check them with a multimeter.
