Its getting time to start planning the Electrical curcuits my plane.
I am looking at the circuit breaker/ switch to act as both Switch and circuit breaker also.

Has anyone had a problem using this method? Pros. or cons
Any ideas?

I'm not the voice of experience yet but I'm almost done wiring and I'll list some considerations I had. The major downside is cost. I have several 3 amp breakers on my panel and as you will note they are the most expensive on the entire list. In my case I had to go back and replace a couple with a higher amperage and now have breakers laying on the table which I won't use. Since I went with w58's that isn't a big hit. Another downside is -- is there any visual indication if they are tripped? (I don't know the answer.) A part of my goal was the very minimum exposure of wires that could short while unprotected. If you use a combination switch/breaker you either have to have it close to the buss bar (maximum protection but possibly inconvenient location) or else have a unprotected hot wire going to your switch/breaker(which you located conveniently). On the plus side is a lot of convenience. They take up much less space. You don't have to worry about the quality of your crimps between a breaker and your switch and save you the labor of wiring a separate switch.

That's my intention also. I think most people don't do it because they cost a lot more. I like the concept of using one part instead of 2 to do the job.
