Our boat has a Webasto diesel furnace that is configured for heating the cabin only. I am in the process of planning to reconfigure it this winter so that the Webasto can also heat our domestic water. I want to have the ability to switch between two water heat sources (Webasto and engine) using electrically controlled ball valves. The selection can be accomplished using a single DPDT toggle switch which I plan to mount near the existing Webasto control switch which is shown in the photo below.

I would like to have a new switch panel made that is similar to this but has one additional switch - the one for selecting the source of the water heating energy. The existing switch plate is aluminum, painted or powder coated black with white lettering.
Does anyone know of an outfit that can create custom panels like this?
