Title is probably confusing - let me explain. In our old bonus room (now a regularly used bedroom), the light switch by the door controls the can lights for the entire room. It also turns on/off the light in a storage area at the far end of the room. So anytime our daughter is in her room with her lights on, the storage area light is on as well. Not a huge deal either way, but the storage area has a dormer on the front of the house, so the light in the storage area is visible from the street.
Can I take the wire from the storage room light and run it to a new switch and then connect the storage room light to that switch? I understand that the new switch for the storage area wouldn't work unless the main room switch is turned on, but would wiring it this way mess up the main switch controlling the room's lights in any way? The new switch would only be designed to control the storage area light, not the main room's lights. Nothing is meant to be a three way switch or anything.
In my mind, when the main room switch is turned on, power would flow to the lights int he room and then to the new storage area switch as well, but if that new switch is switched off, power would stop at the new switch and not flow to the storage area light until that switch is flipped on. Is that correct? Thanks!
