i have a switched receptacle (top & bottom, black & white wire in box) that i want to be always on, and use the existing switch (lower push button one in the picture) for a new overhead light.
hopefully you can see in the picture over the switch box what you need to know. there are three switches in the box controlling four devices. the upper push button switch controls an overhead light. the lower push button switch controls the receptacle. the programmable switch (looks like a box, is hanging lower than the push button) controls two exterior lights. the really close up picture is of the switch box, just to show that all the whites are connected.
