Turn knobs

[Aviator1111]

Hi there!

I'm looking for Airbus type turn knobs for the FCU. Not just looking for, I'm asking if anybody knows what is this at all, how does it work, how it should be wired, how does it communicate, what signs are on its output, maybe it is a simple electronic component which I can buy at home as well. In the bus the knobs on the FCU are also able to be pulled and pushed, while operating a micro-switch which tells the system whether we are in selected or managed mode. So of course that stlye of knob would be the best, but if it is not available, the normal turn knob is also good.

Thanks for your help!
