Incorrect operation of the two-button switch: what to do

Victor asks:

Question: I have a two-button switch in the hallway that turns on the kitchen and toilet. The problem is this: I turn on the toilet, then turn on the kitchen, then turn off the toilet - the lights in the kitchen go out. Why?

Zero fits to the switch from the bottom of the common terminal, and the two lamps that go out to the lamps are lit from the indicator as if they are two phases, I would like the lamps to burn independently of each other, how to do this?

First, a phase should come to the switch - start with this, find the junction box and ring which wire goes to the switch.

Secondly, what are the bulbs? Incandescent? Maybe they are incorrectly connected and when they are lit together - turn on in series?

Did I understand correctly that the light can be lit separately in the toilet, but in the kitchen separately, that is, without a toilet, the light is off? Below I attach a diagram of approximately what you have now, switch "2" when it turns on bypasses the "KITCHEN" lamp, it goes out. But in theory, when you turn on one of the keys, the lighting in the spirits of the rooms should be lit immediately. Perhaps you were a little mistaken in writing your question, but even if not, the solution to the problem awaits you in the distribution box.

How to connect is spelled correctly in this article.
