I finally broke through my mental block (or whatever you call it when you just can't seem to get started on a project) and started my staged RPC tonight.
I've accumulated some "nice" 800T series AB switches in NO, NC and NO/NC Mushroom configs including pilot light; all very cheap $10 for a box full at surplus/scrapper. But I have a couple of questions and/or problems.
First, I've not found any clear indication of the voltage expectations of the lamp. Haven't look that hard yet, but it wasn't obvious.
Second, and more important; checking continuity across the contactor blocks (particularly of the push-pull mushrooms), some of them don't consistently make a good connection. There is some visible dirt in there. I see how the module comes out, but it appears not to come apart without damage. What's the best way to clean these? Just the spray in contact cleaner?
If I can get these switches to work, I'm going to "bread board" (on plywood) the whole thing tomorrow just to make sure all is well before I go making permanent mounts in my nice NEMA enclosure. Assuming the switches are good, I've got everything but the heaters and run-caps so things should go pretty smoothly (I hope).
