Rotary potentiometer with steps/positions

retrolefty:
Well there are/were pots that had mechanical detents, used a lot is older stereo systems to give it a higher tech feel I guess.

Lefty

Agreed, but one wouldn't normally use one of those to select pages on an LCD like OP wants.

A pot with detents sounds like a really bad idea if the pot gets dirty at one of the detents. Probably why they use encoders for that application nowadays.
