Some guidance re control hardware

I’ve been tasked with building a rig to run flight sim, with this I am very comfortable and have many years experience.

However I have also been asked if I can find “controls that resemble a single prop carb run aircraft (carb heater control)” as they have no intention of flying jets and in this I am lost.

Can anyone with more experience (not hard as I have non) help me out?

Like I said, I don’t need a PC build guide, just pointers re controllers

Thanks in advance
