How to connect the backlight and the chandelier through a dimmer and pass-through switches?

Oleg asks:
Good afternoon. The room has two types of lighting planned - lighting in the box, a chandelier. Everywhere dimmable LED bulbs. The idea is this. Dual input switch and dimmer.

Accordingly, either a chandelier or a box is dimmed, or all together if both switches are turned on. In addition, the bed should have a switch for all this or separately. How to do it? The master had difficulties. You can have a simple scheme. thank

The answer to the question:
Good afternoon. You already thought up so many switches and a dimmer yet that you could already look at the smart lights, there are a lot of them now. Anyway. Why exactly 1 dimmer and switch? In your case, it’s easier to put 2 (TWO) PASS DIMMERS!

The circuit is given under the name "Serial connection" here in this article https://our.electricianexp.com/en/kak-podklyuchit-proxodnoj-dimmer.htmlwill be even better. You lying on the bed can make the light dim.

Well, either 1 dimmer and two two-gang switch through passage (or two single-key). The scheme of their connection is in this article. https://our.electricianexp.com/en/sxema-podklyucheniya-proxodnogo-odnoklavishnogo-vyklyuchatelya.html

But your backlight in the box, I assume that it is organized using a 12V LED strip, and it can not be adjusted with a normal dimmer. Based on this, it follows that a circuit with a single dimmer will not work if you use standard dimmers.

If you make it as simple as possible, the backlight box is turned on by one pass-through switch directly, and its brightness is regulated by a dimmer with a radio remote control, and the lamps by other pass-through dimmers or a series of dimmer + pass-through switches (see the diagram below, the last one in the figure).

Otherwise, you need to look for two dimmers (for 12V and 220V) with a 0-10V signal control, but if there are enough such dimmers for 12V devices, then for 220V I could not find an example that I could give in the answer.
