Step 1
Loosen switch(es)
Decide which switches will command the light point (this may comprise several lamps). Loosen the existing switches in the flush-mounting box, without disconnecting the wiring.
A
First loosen the central plate using a screwdriver.
B
Then remove the central plate and the finishing set from the wall.
Attention: This method only applies when removing Niko switches with a square central plate (in the range since 2006).
C
Loosen the existing switch of the flush-mounting box and remove the switch from the wall without undoing the wiring.

Tip: Take a photo of the current wiring on which you can see which wire is connected to which clamp, making it easy for you to identify the current connection diagram.
