if ordering rotary switches from Digikey, most of the ones they stock are adjustable (even if marked as fixed in the product description), so if the switch doesn’t seem to rotate to all of the positions, try taking the nut off and removing the index washer. I just received two supposedly “fixed-index” 12 pole switches which only rotated to 11 positions. Turns out they were actually adjustable and worked fine.
