Thanks for the advice. For clarity, is "on" for this switch (toggle toward the quick connect pole) closing the loop (ie grounding the coil), or is the switch closed when it's in the off position. Unbelievable I called Gaynor (the manufacturer) to ask them how to install this switch, but they claim they can't actually tell anyone how to use the products they sell, since if I were to follow their advice and have a problem, they would be open to liability. Lawyers have hastened the death of common sense.
