William,
I actually have such a switch. It works independent
of even having the master switch on. It didn't occur
to me to activate it, but it happened pretty fast. I
had identified a place to ;and, and had just started
surveying recovery options when the power came back.
I hope that I would have remembered the emergency
bypass switch, but I'm not sure. I'll be creating an
emergency checklist to keep in the plane should the
need ever arise. I hope it never does.
