You can't change the switch logic of going from momentary to latched switches. It wouldn't be hard to build a panel using momentary switches though. You just won't like the price. The regular run of the mill toggle switches are about $40 each. Switch/annunciators like for the APU in your picture are about $500+ depending on the configuration. You would also need a $400 crimp tool to crimp the contacts onto the wires.

Not sure where you buy your toggle switches from, but just to give an idea as to the more realistic price of them:

Would it not be possible to make the switches give the same output for flipping up and down? In the same way, the current "switches" probably give the same output every time they are pressed down, and then the computer inside just tells the car to perform the opposite action that it is currently performing.

Of course one would have to match the physical position (up or down) of the modded switch with the function the car is currently performing (on or off).

With my limited knowledge this could work, even if a OR/AND gate is needed.

Looks the the same to me...

Without having to dig through the schematic, I suspect the current switches just closes the circuit, while the computer cycles through the functions through the software. You won't be able to use a mechanical latched switch to tell the computer what to do, at least not easily.

Modern aircraft don't use too many toggle switches anymore. They all moved to push button style switches for just about everything.

They do make these in momentary, but they are $500+ each.
