This is a very self explanatory one-step instructable. I made this large OFF switch for my Makita MLT100 table saw which has a plastic body. Hence it was easy to screw the hinge to it after pre-drilling some pilot holes.
Now I can turn off the saw with my knew without having to look or feel for the OFF switch. It make the TS use much safer and comfortable.
I was inspired by a post I had seen on a forum of a very similar concept. I improved it by adding a large hole in the plank so that you can easily reach the ON swicth. I used the router with a small roundover bit to smoth the edge of the hole, but you could use a fine rasp or sand paper on a dowel.
Depending on what type of stationary power tools you have, this could be adaped to fit a wide variety.
