Mystery toggle switch - 12 volt panel

Have learned a ton on this forum and appreciate the insight of the group -

Does anyone recognize the toggle switch in the attached picture?

Located on the 12 volt panel in the engine room of our 1995 4000 Express -

Thanks,

Brad

Definitely looks like an owner add on. Turn off most everything and see if it turns on anything. Or conversely turn on everything and see what it turns off. Worse case pull the panel cover and start tracing wires.

Thanks Sans Peur, will do.  Would you expect the emergency battery interconnect to also be on the 12 volt panel?  My manual shows it there in a diagram but noticed the boat has a different 12 volt panel than the manual.
