    12 Volt Panel without Switches on 1994 4388-gctid811659

    I am purchasing a 1994 4388. The 12 volt panel has a main breaker and individual breakers for each circuit but no on off switches for each circuit. I've never seen anything like this and would like to have switches for each circuit in addition to the breakers. My last boat a 1987 3460 had breakers that were also switches. I would like to find breaker switches that will fit on this panel. Has anyone done this or heard of it being done? Thanks, Jack

    That does sound odd. What type of breakers are they? Any photos?

      If they are the circular breakers with the red pop up indicator to show they are tripped that is the standard for the 12 volt side.

      I don't know of a switchable replacement and if there was I would hesitate to change them out because there is so many.

      My 3988 has 28 of them and have never thought about replacing them.

        yep, that's what they are and there are lots of them. I'll do the work but need to find a compatible breaker/switch

          That's standard on many boats, the DC breakers cannot be used as switches. The switches are throughout the boat. You may be able to replace them with aircraft style push/pull breakers.

          The question is why?

            This is a large boat with lots of 12v loads. I anchor out a lot and don't want to have to bug my guests to turn the lights out in the head or staterooms. I've also had problems with accessories in the past, like a blown fresh water line. with the switches I can turn off any individual circuit without having to shut down the entire panel. also if you need to work on a fixture, pump, etc it's nice to be able to shut off the one circuit and leave everything else working.

              These circuit breakers can and are also used like switches on both AC and DC circuits on all the 4588 and 4788 Bayliners. I am guessing that this is something like you are talking about....

                I want to do the same as captain Jack and replace pop breakers with on off switches. Smitty, I can not see the switch you have shown. can you re load?

                Thanks,

                  yes but these breakers do not work the same. You can't pop them manually. They will only turn of in an overload situation.

                  They are also narrower than the switchable breakers that I have been able to find.

                    Have you checked aircraft circuit breakers? They are push-pull breakers and mount in a standard 3/8" hole. Here are some examples:
