Plug In Wall Sconce

My old wall plug-in has given me. I notived most pleasant-looking sconces are all wired. Can I buy a cable and it still work off the light switch, and just change the decision back to normal (rather than being turned off and buy the switch)?

The short answer is yes. The actual wiring is slightly more complex than that. A switch interrupts the hot wire just to open and close a circuit. That being said, you'd be comfortable taking a book from your center before continuing. It will take diagrams that will explain in detail what you have to do.

Yes just delete the exit and follow the instructions in the light of new.

Yes you can, but if you are not comfortable doing it yourself get an electrician to do it.
