I found a place to get reasonably priced Marinette switches usually from stock (most places have a 6 week lead time). The prices below are a bit dated but I think the premise still holds. The website is
www.PocoSales.comMarinette Yachts sells the same switches for $30 and most other distributors sell them for $14 - $20. They are $9.25 at Poco. I d find a distributor that had 1 or 2 of the 3 versions for a bit less ($8.50) but I decided to order them all from the same place.
Marinette uses them in 3 current ratings: 10A, 15A, and 20A.

For those who may not know, marinette used aircraft quality switches with built-in circuit breakers. I am in the process of repairing it but over the years Miss Cleo's owners typically replaced the proper switches with standard hardwares store toggles and panel mount fuses in a variety of interesting and creative (but not good) configurations. I'd guess that many Marinettes suffered the same fact.
