Not quite what I was looking for but something like this. SOme have stops that let you limit the number of positions

In the US, this is all Digikey has that's coded for hexadecimal. My own personal lack of vocabulary for searching is also something I hope to improve as part of this conversation.

Me too! so I am hesitant to make a recommendation for that reason but I think that a 3 pole or 4 pole 12 position rotary switch also does what we want. eg decodes a position to a bit map on the poles.
 

I found the datasheet for Lorlin switches, and I like what I see: lorlinelectronics.co.uk/wp-content/uploa...-ROTARY-April-24.pdf.

This seems to be what's available at Mouser here in the US: www.mouser.com/c/?q=Lorlin%20BCK, and I think that based on what limited information I see, I want BCK1006. I am assuming I can cut down the shaft.

I ordered 5.

 

I have seen those, but I have until now dismissed them as something weird that I don't understand the purpose of.

According to the C&K switches datasheet: www.ckswitches.com/media/1349/arotary.pdf, the increase in the number of poles corresponds to a decrease in the number of positions by a factor of the number of poles, with no further explanation. The schematic just looks like three or four separate switches with three or four positions each, and I don't know the use case for that. I was hoping to get a better explanation here, and it looks like we might be on to something.

Is it possible that this is the exact same thing as hexadecimal coded, just without using those words? And that I don't even need diodes?
