Hm. Come to think about this a bit more, this shouldn't be about property  
values at all.

When you interact with any movable cockpit element, you should  
conceptually change its position, and the only intuitively relevant  
property is the one which controls the rotate/translate animation.

How that sets internal properties is a different matter (there's mode  
switches for instance where the effect of the switch is internally best  
represented by changing a string where increasing or decreasing makes no  
sense at all).

And how these affect the FDM/Systems is conceptually yet a different  
matter (switches may be simulated broken in that they can be moved but  
don't send any commands, switches can be intentionally un-powered,...).

So personally I don't buy into expectations of increase/decrease of  
internal propertues - it's the visual movement of the switch animation  
that counts for intuition (and I expect if I push the mousewheel, I move  
something away from me, if I pull it towards me (clear) - pushing means  
moving switch up, pulling means down (perhaps a bit less clear) and  
pushing means turning right/ clockwise, pulling left/counter-clockwise  
(possibly debatable).
