ohboy lol First of all a three pole switch needs one period of the diagram. Folks, the brass connector is grounded according to my ohmmeter. The switch only sits in one hole, so you'll need some glue. The volt meter is short and doesn't screw onto the back of the 1/4" plywood so the hole needs to be bigger for the nut to fit in. Mine didn't work either and now I have to send it back to have it replaced. Test it Yours before installation.I'm stuck ordering another block like this after drilling 4 holes.If it wasn't for this I would have bought another production.
