My father had a big switch that was originally on a trolley. He used it to
cut power to all the machines so that "the boys" would not get into trouble
with the machinery whe he was not around. Of course we found that by
standing on a chair and hitting the switch lever with a hammer, everything
was on. I used the bandsaw on one of these outings and cut half an inch
into the length of my finger. Never a word, just bandage and hope. Somehow
we survived.
I guess the point is that no matter what steps are taken, little kids
are attracted to the machines. Its probably better to educate them in the
ways of safety than to prohibit.

I have two small children that love to visit me in my workshop. My worry
has always been that one day they may visit the shop when I'm not there
and
some how turn on a machine and feed their hands in. Right now I keep the
door locked and ALWAYS unplug the machines.

I want to add another level of safety by putting onoff / key switch
controllers on all the machines but mounted on the wall well out of the
reach of any child.

Has anyone done something like this and if so where is a good place to
purchase the equipment.
