Assuming the
switch functions correctly (and is wired correctly),
the behaviour of a device with such a switch in the off position
is pretty certain: it's identical to a device that has the
mains lead pulled out.
Not completely. The cord, all the way to the switch, is still energized.
And remember, many of today's devices are not always completely off -
they might tap into the line just a little bit (clock, for instance).
