thanks for the replies. I'm done looking for a new switch - there just aren't any out there - no longer made, and out of stock. Right now, fridge is working, but I'm not confident it will light the next time I want to start it and get ready to use the RV. It's a 1991 Tioga, we bought it in 1997 - we've gotten good use out of it, and in November put 2K of new Michelins on it. I really don't want to put another 2K into it for a new fridge, but if we have to....... might just do it. It's the only big ticket item left to replace.
Stay safe, stay healthy.
