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.
