[simpits-tech] Sourcing SP3T 90 deg index switch for Cessna 172 cockpit

[JOHN POWELL]

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.
