I like this idea.

Strictly, they should also be the right sort of switch. I forget the
name, but they're designed in such a way that a broken switch can't
accidentally short together inside. Big cam isolators do it, recycled
light switches don't.

And if your isolator is there as an _isolator_ too (i.e. electrical
isolation, not just cutting the mechanical power) then make sure it's
a double pole (for single phase).
