Why does the backlit switch not work?

New house! The double light switches after the builders worked fine! I decided to exchange for backlit switches! At the same time, the backlight does not seem to be on, and one light turns on from one key, and the second turns on only when the first is on. If you turn off the first key, both lights go out! I put back the switch without backlight - everything turns off and turns on normally! And this is currently in 3 rooms! But I think that there will also be in the corridor and the kitchen! I tried to understand something, but there was not enough knowledge !? Tell me what to do? Thank!

    Hello! Look carefully at the new circuit breakers wiring diagram. Most likely you are connecting them incorrectly, so they do not work as they should.

    Thanks to the admin! I would never have thought that it is really necessary to look at the circuit on the switch, I had never encountered it before, usually it was that from the side where there is one contact - there is a phase! And then there really is a phase from where there are two contacts! Thank you very much! And it was somehow strange for a teapot!
