Disconnect Power

To prevent severe shock or electrocution, always disconnect the power at the service panel before installation. Only licensed electricians should carry out the installation.

Remove the old switch and disconnect the wires, please make sure that there is about 5mm of bare wire exposing.



Insert a small, flat screwdriver in notches on wall plate and twist gently to pry from frame to remove wall plate.



Connect the wires to the switch case. Make sure that the wires are secure.

Fasten the switch on wall by placing the proper wall mount components.



Turn on the circuit breaker and connect to the power.


Test your switch by tapping 2 to 3 times. Your lights will be on/off.



Snap wall plate to frame. There are four click-stops for adjusting the fit of the wall plate to the switch
