I am trying to design a user interface that consists of several knobs which can turn (duh), be momentarily depressed (clicked), and can be backlit, based on whether they have been clicked or not.
I was thinking of finding some sort of 'clickable' potentiometer and mounting an LED next to it, underneath a semi-transparent shield of some sort.
However, I have had no luck finding these 'clickable' potentiomenters and I also thought it might be somewhat difficult to configure the LED properly as I described.
Does any sort of potentiometer exists? Is there a different route altogether that I should be taking to get the knob, click, and backlit functionality that I want?
