How to turn on the chandelier and sconces from different places in the bedroom?
On the other side of the bed also need to turn off the chandelier? Then it is no longer pass-through, but cross-switches are needed. Rather, at the first and last point - walk-through, and at the middle - cross.
It turns out that you need to put a cross switch on one side of the bed, and on the other side of the passage. It’s easier, of course, to put 2 one-key keys, 1 of which will be a switch, and the second a pass or cross switch.
But you can have a two-gang walk-through and cross-keys with the same button and frame design (see Legrand).
This article describes how to connect cross-switches.
