Rotary Clicker Input Gadget Type Thing
(OP)
The Bosch ovens in Europe used to have a knob to turn that set the desired temperature. Their would be about 10 or 12 clicks per rotation. But the neat thing was that the electronics would increase the rate of change of the desired temperature according to how fast those clicks were coming in. So if you turned the dial fast, each click would correspond to say, a 10 degree jump, or even higher. But as the click rate fell, each click would cause a 1 degree change in set temperature. Man, it was really neat. Now the cleverness was in the electronics, and the knob, complete with clicker, must have been a fairly simple device.
I have stumbled into an application where this exact arrangement would work really well. The problem is, I can't find any vendor who sells the rotary switch, which is what it really is when you get down to it. I imagine the switch would have a single common with a contact each for clockwise and anticlockwise rotation. A dozen indents or cams internally would mechanically fire the contact as the thing was rotated. Does this make sense? I am on the point of building my own (I'm getting frustrated) but I'm putting the question here before launching myself into that. Does anybody know of such a switch?
Thanks in advance, and apologies for being long winded.

This way, with one direction of rotation, "A" will always be high aleady when "B" goes high. When you reverse rotation, "B" will be high before "A" goes high.
It will probably be a lot easier and cheaper to by an optical encoder that basically will do the same thing.

Optical was the part I was missing. I've got some suitable part numbers now.
The offset cam idea is something I need to remember. But as you suggest waross, the path of least resistance is just to buy the device.
Thanks again.

Go to Digikey.com
1) Keyword search for "encoder switches"
2) Under the categories that comes up under 'switches' select "Encoders"
3)In the first category 'Detent' select "YES".
Then name your poison. Might base it on price - look at them all.
Or base it on reliability - pick capacitive or optical.

But optical would be better in almost every way.
