Duke,

Thanks for the info. I have the replacement switch and it is much beefier in construction than the one in the car. I wonder if failure of these things is common.

The existing switch seems stuck in one position, or not moving properly between open and close, and does not make clicking sounds like the new one. I hope it is indeed the culprit. Sure sounds like it.

Also, it is not a "Sender Unit" as I said earlier. The dealer made a mistake. It is a "Thrust Cutoff Switch" which I believe it has been referred to here in one or more threads.
