I've seen some things turn on by themselves, or more likely *not* turn
on. Usually what happened is the switch is either not in a full off
position or defective. The switch not being in a full off position is
difficult on most of the power tools I've used.

I am on the fence on this subject. I have never seen one turn on by
itself. I have seen some tools turn on because the switch is easy to bump.
I have seen things turned on because someone else turned them on by
mistake.

I guess I almost always unplug while making any adjustment or tool change
where body parts will be very close or in contact with the sharp rotating
things.

The exception is that for a quick change while I am alone on the table
saw,

The very time when you need somebody around in case you bleed out.

which has a magnetic starter. I can't see how that could ever turn on by
itself.

Which tools should have, as they cannot start if they were shut down due to
a power failure and the power is restored. No foul if the TV comes back on,
but power tools are a whole other story.
