Ace,
Others have already mentioned Waytek Inc (
www.waytekwire.com), and here is another favorite electrical "stuff" supplier that I use: Del City (
www.delcity.net). If you go to the Del City web site, look for the small round rocker switches part number 7500020 (SPST). This is the non-illuminated flavor, but you can also purchase them in a choice of four illuminated colors.. Also the non-illuminated ones are available in a variety of pole configurations, such as SPDT for making a three-way set-up. Good for that entry switch you were wanting. The other three-way can be located up front near the driver if you choose.
As to hunting for a pre-fab marine breaker panel ... yep you will find them but they are costly and what I have found would not do exactly what I want. Best make your own, it is not a major event ... just noodle out beforehand what you want it to do, then set down and draw up a schematic. Parts are available from the above noted sources as well as:
Allied Electronics (
www.allliedelec.com)
Newark Electronics (
www.newark.com)
They may ship you monster sized catalogs similar to the NYC yellow pages.
I may sound like an electronics whiz, but I only hold the degree of the school of BTDT. I have the shop full of useless parts that I ordered to prove it. Now that I have my electrical system up and roaring, I know how it should be done. Learned the hard way, however.
Trust me on those little rocker switches, they are the neatest little dudes you have ever seen. Rated for DC or AC. Easy to install in a switch plate of your making ... drill a 20mm hole ... push the switch in ... shove wires onto the terminals, and you have a neat installation.
Several locations in my bus, I used 1/4" Corian for the switch plates, and other places 5/8" curly cherry. Up front over the driver area, there is a master control set of switches ... all color coded to the source. Green for circuits powered purely by batteries, yellow for circuits coming off of the inverter, and red for those powered only by shore or genset. These switches fire the relays which are located mid-ship behind a little door. Reason for the relays was to keep the 120vac from having to run directly to the switches. Therefore the switches only are operated on 12vdc. Sort of a nice idea to save having husky wires all over the bus. From the output side of relay to the lights, water pump, stove top, air conditioner, whatever ... goes the heavier wires.
I didn't mean this to be confusing. Now I'm confused when reading my convolutions.
