welcome everyone, I came up with this little trick, namely the light was supposed to turn on for a preset time on the staircase after touching a metal handrail. I bought a staircase switch ASO-205 controlled by a short-circuit switch and an electronic touch switch EWD-300, which was supposed to be colourful but failed.
The touch switch does not give full voltage, yes the bulb lights up, but there is not enough voltage to operate the stair switch.
I thought about a relay with a 220v hold but I can't find one.
Please give me a diagram or a hint, thank you,
