For my dash I need to have 4 buttons:

Up
Down
Select
Menu


I was wondering if anyone knows of a thumbwheel that gives an output I could use to do the first three all in one go?

Like for example I know that some car stereos stalk controls have a thumbwheel that you can push, so it has an up function and a down function and another one as well, but what sort of format is the output? Is it as simple as a common in and then 3 wires out or am I not going to get that lucky?
