I want to use switch to have A and B connect to either 1 or 2 and 3 or 4 depending on DPDT position.
My problem is A and B generated so they are not same voltage. DPDT wiring diagrams I find show that A and B are common.
What do you recommend? Is it possible to do? or do I have to use 2 SPDT switches?

A and B do not have to be common, depending on how you want to wire the switch. In effect, a DPDT switch is actually two SPDT switches, but they toggle both at the same time.

From what I am guessing, based on the post, E.M. is correct, that s four-pole double throw switch may be the solution .
But even a crude drawing may help.

Do you mean this?

Position 1: A connected to 1, B connected to 3.

Position 2: A connected to 2, B connected to 4.

If so, that is what a DPDT will do, and A and B can be different voltages.

Hi NAGIBATOR_228,

I suppose you require this one.

It's a double-pole, double-throw (DPDT) switch.

A & B are not interconnected.

Nandu.

Sorry I don't understand why the picture didn't load it showed up in the message.
Bob I want exactly what you describe. But idk if switches that sell as DPDT have center pins (so A and B as I understand) connected. What do you think?Untitled.png
