is there such a thing as a slide or rotary switch that mechanically encodes binary contacts for 6 or 8 bits?
Thanks!

Well, it wouldn't have detents, but you could use a rotary encoder wheel and a micro...
I've only seen 4-bit (16 position) binary switches, but that doesn't mean they couldn't exist. 64 or 256 detents might be hard to make mechanically, though...
From memory, Burns makes (or made) a 7-bit mechanical absolute encoder (128 positions). It used some kind of modified Gray code that could be realized with a circuit board, IIRC. I have a sample of it somewhere.
There are optical absolute encoders with at least 10-bit resolution, but you might not like the price.
Of course, incremental optical or mechanical encoders are inexpensive and easily available.
