    Hello,
    I wanted to connect a doorbell, unfortunately I'm not very familiar with what I encounter.

    The case is as follows, there are 2 wires in the switch box, and the switch looks like this:

    There are also 2 wires in the box in the wall (power supply). I came up with this connection scheme:

    Is it correct?

    I don't quite understand what you wrote, but the bell switch should only interrupt the phase wire.

    And I thought it was the other way around. The switch shorts the phase wire when I press to ring, otherwise it's a tarabani chime all the time.

    Yes. you wrote ok.
    Earlier I wrote that the bell switch should be installed only on the phase wire and not on the neutral.

    So is my diagram correct?
    Except that there is probably voltage in the wire that returns from the switch to the doorbell (I don't press the switch), because the diode in the tester (screwdriver) is on. It only shines as if weaker than on this wire entering the switch.

    That is OK.

    Is it the fault of the switch and not isolating the phase?

    Is the bell button?

    The neon lamp glows but weaker because a small voltage is induced in the return wire from the connector because this wire runs parallel to the live wire going to the connector - the neon lamp is very sensitive and therefore glows slightly.

    Thanks for the enlightenment :-)

Topic summary

The discussion revolves around connecting a doorbell using two wires in a switch box and two wires in a wall box for power supply. The main concern is whether the connection scheme proposed by the user is correct. Responses clarify that the bell switch should only interrupt the phase wire, and there is a mention of a potential issue with voltage in the return wire from the switch to the doorbell, which may cause a weak glow in a neon tester. The phenomenon is attributed to induced voltage due to the proximity of the live wire. Overall, the connection scheme is deemed acceptable, with emphasis on proper wiring practices.
