Question on the safety switch?
 

If the safety switch is installed so that the case of the switch touches the frame, does that create a ground and nullify the purpose of the switch?? I know it is a switch in the positive side (which is ground in the Mod A) but if it touches a ground , what happens electrically? Thanks in advance.

I don't know which one you're using, but the outside should be insulated. As long as the poles don't touch... you should be fine.

If you want to cut off the positive ( model A ground) and this touches the ground (so, the positive) there will be NO cut off. As simple as that.
But why installing a cut off switch that is n,ot isulated ? That is the question...
