Grayhill Rotary Questions - for Garmin 530 GPS Module
I checked and indeed DigiKey does have the Grayhill dual-concentric rotary encoders with pushbutton. A have a couple of follow-up questions:
1) What detents should I get for the inner and outer knobs - they have many to choose from.
2) Does DigiKey carry the knobs to fit over the shafts for these? If so, what part numbers? Specifically, the bottom knob needs to slide through the shaft so the outer knob can fit over it.
3) Has anyone had experience using the Grayhill GH65C11 Rotary interface chip? I want to create my own rotary decoder board and am looking for comments on that interface chip.
By the way, this is going to be used for a Garmin 530 Panel. I have already made one a couple of years ago, but I didn't have a separate screen for it (I just had it displayed on a monitor). Also, I had to use 2 separate rotaries and a separate pushbutton for each dual rotary. The new version will have it's own 6" screen, and will use the grayhill dual rotaries and should look and operate exactly as the real thing!
Thanks for any input!

Knobs for Grayhill Encoders?
Correct - DigiKey has the encoders, but I do not know where to find the knobs for them.
Anybody find ones that work?
