vranasakis In all countries electrician don't put blue wire(neutral) to the switch holes on the wall. Unless is power outlet under the switch and is bypassing through switch hole on the wall. All electricians do the same.

BG161211812 Hello vranasakis,
thats Not correct. In Germany You have to Do the safe Way with 3 Wire for everything, included Light-Wire : Blue-Brown-Yellow/Green
If Not You can Die, the incuarance cant work finely without the 3rd Wire.
Best Regards.
