I have two small children that love to visit me in my workshop.

Know the feeling.

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.

I just bought a lock to fit my subpanel and I throw the main breaker and
lock it off. All the suitable switches I found were either not rated for my
power or way too much money. Of course I said this on the wreck before and
was admonished for improper use of a breaker, but it works for me.
