Bob, only one thing I can think of is that I was told in electronics class not to use sand paper to clean contacts as the grit can become embedded in the contact material. We were told to use a fine contact file. I see you used a wire brush to polish them which is helpful. As far as the contact pads... they are the same type as what is used in electronic calculators, cell phones etc. I wouldn't scuff them with 400 paper, just use contact cleaner so as not to remove the contact pads. Glad all is well now and I will be doing the same thing on my door window switch. I like your idea of using shims.
