Exterior Docking Station Switch
I am trying to help my in-laws determine a switch’s use on the exterior water connection panel. There is a rocker switch to the right of the light and above the city water connection in this picture that we cannot figure out what it does.
At first, we thought it was for the panel’s LED light. However this light appears only to be controlled from a different switch just inside the main entrance, adjacent to the steps. Does anybody have an idea what this switch does?
