Just a bit of a tip. After I took delivery of, and installed the new one, I thought I'd open the old switch just to have a look. There appeared to be a couple of tabs that needed to be depressed to allow for separation of the switch body. But I had no luck getting that to work. So I thought, since I really had nothing to lose, I'd get more aggressive with it, and inserted a knife blade between the two halves and gently pried them apart. The switch body split in two. Internally it's a very simple operating system, and the contacts were a dirty mess. I cleaned all the contacts, and snapped the two halves back together, and now the switch works perfectly. If I'd operated on the old switch before ordering a new one, I would have saved myself a lot of money.

So if you run into a similar situation, maybe this post will help.
