Jon, I just spoke with Micro Switch Corp, now known as Honeywell Corp! - 866-288-7272. The name changed many years ago. I talked with customer service. There is probably not much they can do to help us because that Micro Switch unit in the picture was just part of that contraption in the other pictures, or was not even related to whatever that is attached to that valve cover.. BUT, on the bottom of the picture is a Catalog Number. But, I cannot read that number. IF you can clean that unit up and read that Catalog Number, tell me what it is and that will help them trace back to see what that is and what it might have been used for. It would also help if you turn it around, look it over really good and see if you can find a Model Number...
