Unknown electrical switch??

[SpcAlan1]

I am redoing my DC panel to something more modern.
I have posted 2 photos, one of my original DC panel, and a photo of a switch that is not labled . When I flip the switch to 'on' the little light comes on.

Does anyone have any idea of what this is?http://www.sailnet.com/photogallery/.../ppuser/166433

Hopefully the link works.

Looks like it's your AC panel so the switches would be for whatever 110 volt circuits you have. Battery Charger, Water Heater or AC outlets in the cabin.

Ok, I will have to play around and find out what they do.
I do have a water heater and ac outlets.
my battery charger just plugs into the AC outlets when plugged into shore power.

I am plannng on moving the perko switch and replacing the 7 switch panel to something new, and adding some monitors ( 2 batteries, maybe total draw, and the override for the bilge pump.

It may be a switch to turn the battery charger on with an indicator light showing the charger is on.

Or a switch to turn the water heater on with an indicator light showing the heater is on.
Or it may be connected to nothing with an indicator light showing the switch to nothing is on.

Isn't that the Self-Destruct Switch???

don't know for sure, but I do know that my battery charger plugs directly into the AC 110v and then to battery.

very possible... but how do I find out?

Somewhere in the Atlantic, there is a lighted bouy blinking on and off as you flip that switch.

Assumption is that because it is close to the AC panel, it has something to do with AC...

The two most common AC "options" are (as others have already pointed out); Battery Charger, and Water Heater. Because there is a light on it, I would guess Battery Charger.

However, because the boat looks to have some, uh... non-standard wiring, it could control virtually anything.

If it were my boat, I would be rewiring EVERYTHING connected to this panel with tinned - stranded - Marine grade AC wire.

Hey, also see my photo of the IMI Combi box ( under the port side cockpit seat ). It is going to the panel above the wheel, but I have no instruments in that panel... what exactly does this thing do?
