I haven't seen a rotary switch with 90 degree indexing for years. You might be able to modify the indexing on a more standard switch, but I prefer your idea of using a disk or cam with micro-switches. Sounds like a great 3D printer project.

I'm looking for a source for a 3 position switch with 90 degree indexing for my Cessna 172 cockpit. I need it for the fuel tank selection lever.

I have been able to find the exact switch that other commercial simpits providers are using, but I can only buy it in lots of multiple 1000s.

Has anyone else seen this switch or another like it available in singles or small lots?

If I can't find a 3 position switch like this one, I am contemplating using SPST limit switches and having a disk behind the switch that selects left/both/right tanks.

Anyone else tackled implementing a fuel tank switch at the bottom of the Cessna 172 center console?
