The problem is that most switches listed as on-on-on work like the one on the left.
Daz needs one that works like the one on the right.

No,, I didn't check any of the data sheets. I just found a bunch of 3-on listings. I don;t have time to do the complete research, it was just a suggestion.
The PV part may well not be what we need, it was just work checking out.
First three digits on PV part numbers are overall type and source.
713xxxx is a switch from domestic sources (Meaning Mississippi warehouse.) They same part numbers starting with 3 means imported. Any time you need a PV part from before that starts with 7, you can always try asking for a 3 series. Like pots, they all translate that way.
The last five digits determine the actual type switch.
302(702) - resistor
303 - cap
304 - semiconductor
307 - speaker
311 - potentiometer
313 - switch
314 - jack
to name a few common ones.
rjb, even if you are right, in a sound system, we can leave the common wire unswitched, and short the two center posts together and use those types. One channel. You want stereo, gang two or use a 4 pole type.Education is what you're left with after you have forgotten what you have learned.

I ran across a full-sized 4 pole double throw*** on-on-on switch working on a 1,000,000 BTU "blast" furnace used in an autobody shop 15 or 20 years ago. The company that tried to repair it previously did not know about on-on-on switches so the switch that they put in did not work properly in the middle position.
I called it a "blast" furnace because there was no vented heat exchanger - the flames just shot out into the large room where the painted cars were "cooked".
*** It might have been a 2 pole switch but after all of these years my memory is just a blur...

P.S. I was perplexed a bit at first about the solution Daz posted because I only know of on-on-on switches as shown in the left drawing in Post#18... BUT if you jumper the 2 center terminals together you can select one, the other or both. You do need to ohm out the switch to make sure you are using the correct terminals...
