Buying or Building a Rotary Swithc with Push and Pull function

Sorry to re-open an old thread, but better than starting a new one i guess.

I'm about to start building an A320 FCU.

Could the push pull function also be done with a normal rotary encoder and a toggle switch with some sort of connection made?

Yes it can work, but I think it will be very complicated to use.

If I understand you correctly.
You want one rotary to do a function, of LEFT rotary, RIGHT rotary, PUSH and PULL buttons, using a one ratory and a mode switch button.
Then I you switch mode for rotary the LEFT rotary can be used as push and RIGHT as pull?

If so, like I said, I could be complicated to use.
