O.K. I found the old switch. Took some pictures for those who are curious.
In one of the photos you will see a round "plunger" which is pushed on by the water pressure. There is a "white" rubber seal to keep the micro switch dry. The micro switch is held in place by 2 little posts. Also, note there is an adjustment for the spring which exerts pressure on the plunger at the top of the switch housing, under a rubber grommet. (I tried adjusting it when I experienced my problem, but it didn't help. I believe the plastic plunger may have developed wear from use and was hanging up. Just a guess, as the switch still made contact when I tested it with my multi-meter.)
One last note: Back in August of 2014 - when I experienced my water pump problem, I called Headhunter about my situation. When I told them my pumps serial number, the guy said: "That pump is too old, we don't have parts for it, but we are having a special! You can buy a new pump for ..." I told him I would consider it, then called Newell. (Should have called them first!) I forget the plumbing techs name, but as soon as I described my problem he said: It's you water pressure switch. He transferred me to Chuck in parts. I had the part the next day!! PROBLEM SOLVED. With service like that, I will always call Newell first. For my money, if it costs a bit more, so be it.... just my opinion.
Happy New Year to all. See you on the road. Jerry B
