Sorry to correct you but nearly all 110V control systems are end tapped to earth. The reason being that an earth fault could hold a coil in making the e-stop inoperative.

Hi Tony,

Thats the way my old gaffer used to get us to wire them, but when we wired in the e-stops (usually via a pilz safety relay) it would kill both the legs of the 110v so therefore isolate them completely under an e-stop situation.

Wiring a new 2 gang switch from a single two way switch.
"It works" and "it's safe" are not necessarily the same thing. With DIY work, they are often far from the same thing.
