Ok, here's the scenario: The dining room in my circa 1935 home has a single lightswitch wired to an overhead chandelier. The chandelier is on its own 20A breaker. I want to add a few low voltage recessed lights to the room and, because they are easily reached and there is ample capacity, it makes the most sense to tie into the power line going to the chandelier.
The wall switch for the chandelier is in a metal single gang box that is nailed to a doorframe stud. It would be quite easy to cut an opening in the wall immediately adjacent to this box and install a plastic single gang remodeling box. Is there a way to do this such that a double gang wallplate can be used over the two adjacent switches to give a neater appearance? If possible, I would like to avoid the removal of good plaster that would be required to take out the existing box and replace it with one double gang box.
Thanks in advance for the help!
