Superfluous switches

[tiburon]

As my overhead is nearing it's completion I'm starting to think about connecting the switches to my interface cards. The Simworld overhead of course has all the switches but do I need to connect them all ?
What I would like to ask the esteemed forum members : which switches do you consider superfluous ? For example : one switch probably suffices to turn on the landing lights ? The ignition switch, does it do anything in the simulator? I'm connecting to Prosim737.
I would be grateful for some input (pun intended), freeing up some space on the overhead and on the interface cards would be very welcome.

Ah well, I guess nobody here is building an overhead......
