Dear All,


I´m firing my mind trying to solve the problem.
The question is how to insert a relay, or coupled-switch, to perform that comutation.

Note that right wiring of right winding is not connected to nothing at your circuit, whilst at the other circuit is connected.
Can you see any advantage, disvantage at each one ?

What`s your point ?????
Both schematics use DPDT switch. (Post#2 & #3)

The (less important) difference is the series connection of two contacts in you schematic. If you prefer the symmetry for aesthetic reasons, you should go for it.
 
Hi guys,


After a more acurate analysis, I noticed that both representations refers to the same topology.
thanks a lot.
