Why does one lamp go out when you turn on the second?
Good day! There is a problem! I changed the wiring, everything seems to be working fine, the old Soviet switch with three petals and a socket! I turn on one, it burns normally! I turn on the second, the first goes out! I turn on the third, the second goes out, the first turns on! I’m afraid to stick a plug in the socket, what should I do? Help good people!

Please specify in more detail these moments - I turn on the second, the first goes out! I turn on the third, the second goes out, the first turns on !!! I’m afraid to stick the plug into the outlet. It is not entirely clear what is happening.
It looks like the wrong phase / zero connection.
In the chandelier, three wires of zero from three horns are twisted together and, in theory, should be connected to the zero wire in the ceiling. And three phase - from three phase wires coming from the switch, each separately.
But now let's say that three twisted wires are connected not to the zero, but to one of the phase wires.
You’ll get about the following effects. Every single horn will still work. Either the phase and zero will be connected to it (only interchanged), or the phase and another wire, which in theory is phase, but it is disconnected from the switch side, therefore, as the phase does not work, but through twisting and through that horn, which still connected to true zero, this wire will be connected to zero, and the current will go according to this complex circuit - through twisting and another light bulb. But suppose we include two horns, one of which is connected to a real zero. It is he who will definitely catch fire. And the second one - it turns out that there will not be a voltage drop, on both sides of the lamp there will be the same phase, connected from the side of the switch via two wires. This is for incandescent lamps. With LEDs and fluorescent lamps it’s somehow more difficult to get out. They incorrectly connect the phases poorly withstand. I just messed up like this now, and in one version in my chandelier the LED lamps do not turn on, but, thank God, half the lamps are blinking, in another version.
It is not clear the device of the switch, is it a 3-key (in 3 directions) switch combined with an outlet? Or a 3-band switch combined with a socket ???
