Double light switch wiring: how to connect two lamps to one double switch?

Hello, I have a question about connecting a double light switch - I'm not sure if it's professionally called. The idea is to turn on one lamp with one key and another with the other. After a dozen or so attempts, I gave up.
Effect:
Either both lamps are on at the same time (switched on with one key), or otherwise, pressing the key causes the second lamp to light up alternately, once once, without the possibility of total light only.
Below is a photo of the connector and cables I have and the "diagram". With such a connection as shown in the picture, only one lamp works.
When connected as shown in the diagram, both lamps work, they are turned on with one key, pressing the other button does not change anything.
1 and 2 - brown cable
3 - gray
4 - black

Thank you in advance for your help and best regards.

You added the picture wrong, write how many wires you have for the chandelier and how many in the box from the connector. You should have three. From what I can see, this is probably not the switch you bought.

There are 4 cables by the switch, two brown, 1 black and one gray. Previously, both brown ones were connected together, but I disconnected them. One of the brown ones goes down the forest, I think to the socket below.

And what was installed there before? The brown ones you probably shouldn't separate, because it's probably the coming and going of the power supply.

How many keys do you have on this switch and how many terminals.
Maybe it is a double staircase and not a candlestick one?
Since the brown vein goes further down, connect them together and see if you have power in the socket you mention.

You have the wrong switch, buy another candlestick with three clamps, and this one, as I can see, has four, i.e. a staircase, as a friend writes.

Hello, a double stair switch can work as a candlestick, I've recently installed one myself.

Previously, the "dimmer" was connected and only one lamp was working. It is possible that I bought the wrong switch. There are two buttons and the terminals as shown in the diagram are 3 pairs at the bottom and 3 pairs at the top. So theoretically, there are 12 places where cables could be connected.

I corrected the photo, it is now in a large size so maybe it will be easier to deduce something

There are 12 terminals, but rather each is double, i.e. 6 in total, I think it is a double staircase.

Yes it is a double staircase. Make a bridge and connect the two brown ones together, but do not disconnect them from the switch. Then each half of the switch will have electricity, in the staircase you have to do so
acted like a candlestick.

You must disconnect the black wire and plug it in the x11 or x12 hole, and in its place, plug in the bridge and connect it to the other brown wire.

I suspect that the black one is plugged into x12 so probably ok. You only need to connect the 2 brown ones (bridge between L1 and L2) and it should be ok

I guess it's not plugged in x12, take a good look, it looks like it's plugged in right next to the brown one?

Unfortunately, we do not know what is connected to the brown wires. By the way, you are not drawing any conclusions from the disconnection of the brown wires. After all, you turned something off, you are waiting to be discovered in the future. Following your descriptions, I suggest you perform a small operation in the form of connecting the brown wires together, leaving the rest as is (refer to the photo). Probably it will be possible by putting a bridge in the holes adjacent to L1 and L2 (guess).

I assume that brown is a phase, suggesting this downward path, probably to the socket, but I am not sure, unfortunately the author did not write which wire has electricity in it, and I don't think he is interested in what we are writing here at all.

In the evening, when I get home, I will test it. Thanks for the tips and quick replies

Only today I had some time to connect the lamps. I connected according to the instructions, i.e. I made a bridge between L1 and L2 - blue cable and next to it brown, black cable in X22 and white in X11. Everything works fine. Thanks again for the tips and best regards.

I close.
