New way to wire lighting circuits

It makes most sense when lighting circuit is fed from below - i.e. the upstairs lights and loft lights. Then LNE arrive from below the switch and leave to the light above. Otherwise it can be wired rather as a 2 way light switch, wired in 3core+E, with 2 cores L and SL as before and the other one N.

I'm not aware of any switch with a parking contact for N, though I am aware of cases of it being stuffed in the back contact of a 2 way switch, which in effect shorts out the light when it is off.  This is not wise, and confuses the unwary - the smallest wagos or a slice of chock block are your friends.

Don't forget blue sleeving is available as well as brown.

There is a modest EMC advantage to the fed from below method (not for health, but in terms of RF pick up or emission, as in the looped out method we have in effect got an antenna like a folded dipole on the L and not the N, so any differential mode L-N signals are now radiated.) With well filtered equipment this is not necessary.
