Ground remains ground in any scenario. If I'm not right on target i think I can figure it out with the materials and a meter in front of me. Thanks The Pol, love reading up on all your electrical comments.
Yes, you should basically (if I had the switch in front of me I could be more certain) have a neutral going in on one end and a single hot going in on another. The other hot will jut be running to the element (outlet) however you have that configured. This way you will have for instance a CENTER OFF position, LEFT 120VAC position and RIGHT 240VAC position. Grounding will remain the same.
This switch would probably be like a motor switch (high amp) that is for reversible motors for example.
Never done this, but this is what you need to do, three positions. (2) separate LINES in with one common LOAD going out.
