I have a wiring dilemma. I have a friend who redid most of his kitchen and now he asks for wiring help. There is a light above the sink which formerly had a pull chain on it. The new fixture they want there, of course, does not have a switch built into it. Because the walls are now finished and it would be a major project to get a wire to a switch, I though a remote switch might be the answer. However, I have been unable to find a simple battery operated off/on remote switch that would fit in an outlet box and have a receiver to control the light fixture. There is an existing box in the wall but there are no wires in it. I can probably get power to that box, but not a wire to the light. Does anyone have a suggestion where to find something like that or a better solution to the problem?
