Hmm...
I was looking at my swithches, and the driver side definitely feels different. When you press it down, about halfway you can feel a little click. That tells me there is something definitely mechanical happening with the switch.
So there are two questions left:
1) are the switches easily interchangeable? If are they all soldered to a PC board, that gets ugly. Or if they have different # of wires that is definitely a no-go.
2) does the computer control the actual movement or does all of the control come from the second switch function?
If I had the time, I would pull it apart this weekend and swap the swithces around. But I have triplets, and my life is hell, so maybe someone else is daring enough???
