I then the electrical connection by putting all the blinds in series and there nasty surprise for some unknown reason blinds react differently when they are connected and only when they are connected in series! In the latter If the initial adjustment does not work: they rise too high, down low, etc. ...
Strange ... The principle of the switch is simple: the current is sent up on a thread and descant on another thread. By controlling only now with a multimeter I realize that when the current reaches 230 on a wire it is up to 280V on the other thread. At the same time I can reproduce the behavior of the blind if I send the current on both simultaneously son. I do not know surprised that the blinds are disturbed by the stream returned by the others ...
