I wonder if they could theoretically rest on top of the notch, not fully locked into either position and flip accidentally. No idea how the switches behave when not all the way up or down, but the notch looks pretty long and flat so it could be possible.

Something like this could maybe happen to one switch, it's unlikely but possible. But two independent switches at the same time?

Good point, that is very unlikely. I was just wondering if it's possible at all.
