I am trying to connect the momentary switch to a dimmer 2.
I already do understand that the dimmer 2 will work (even without a switch) when the Brown =>L, Black => O and Blue => N have been connected.
I have succeeded to get the software connect to the dimmer and configre it.
Now, what I do not understand is the way the momentary switch shoud be connected to the Dimmer 2.
See attached fig 1: the momentary switch has been connected to SW1 (or SW2) and L.
However, on the Shelly Dimmer I do see 3x a L. Are these 3 L identical?? Are they in parrallel? And if YES, can I connect the momentary switch to a random L?
See also attached fig 3: the in figure, the momentary switch has been connected to SW1 (or SW2) and N.
So, for me, it is strange that in fig 1 the momentary switch is connected to L and in figure 3 to the N ???
Or can both ways be used??
