Installation

⚠️ Always disconnect power at the service panel before installation. Only licensed electricians should install the switch.

1. Turn off power at the breaker.
2. Remove the old switch and expose approx. 5mm of bare wire.
3. Pry off the wall plate using a small flat screwdriver.
4. Connect wires to the switch terminals according to the wiring diagram.
5. Ground the device as required by local regulations.
6. Secure the switch into the wall box / 120 socket frame.
7. Restore power and test by pressing the button 2–3 times.
8. Snap the faceplate onto the frame.
9. Open the Yoswit App — the switch is auto-detected.

Optional LED stabilizer:

If 2-wire installation causes flicker/no light, use 3-wire (with neutral) wiring or connect an LED power stabilizer across any lamp as shown in the manual.
