Could get a little tricky if you want to light both LED's at different positions. .
We could use the switch for a non brewing project, useless I think.
Based on the color of the LED's we can identify an unknown voltage applied to two terminals as DC, DC polarity or AC.

Just leave the switch in the on possition and use four diodes and one resistor.
As long we use low volts and forward current no other parts are required.

I think we have this guy confused enough.

Really, a little H-bridge would work nicely for changing colours.

Righto. I've got a plan and actually understand what I'm doing. I think. My biggest issues come from the idea that I generally understand the concepts but I don't know the terminology, which - clearly - makes things a bit muddy. I'm coming around though...

Ok. I'm off to harvest an adaptor and source some resistors and whatnot. I'll check in later to let y'all know if I blew myself up or not.

From the PDF you provided and the model number, the switch is one common and two discrete poles for the two LED's.

From the PDF:

12vdc + -----/\/\/\/------- Pin 5
12vdc - ----------------pin 4 ------jumper------ pin 6

From the schematic on the pdf, it looks like there might be an internal jumper. Put a meter on it and see if you have continuity across 4 and 6. If not, solder a jumper on it.

cool switches btw.

You could have just got 120V switches/indicators and saved yourself time and $$.
