An outlet is a point on the electrical wiring system where electrical current is taken to supply equipment. An outlet can be a wall receptacle, light fixture, smoke detector, and an appliance. A wall switch is not since no current is taken at a switch; current is simply passing through.
Lighted switches are the only switching device in common use that is also an outlet.
The delineation between the definition of a switch as a device and a switch as a possible outlet only becomes an issue in the case of a switch in bedrooms areas that control outlets outside of the bedroom area. An example of which would be a switch inside the bedroom that do the lights on the deck outside the bedroom’s exterior French doors. People puzzle on whether to AFCI protect this circuit, since the switch is in the bedroom, but the actual outlet (the lights) are outdoors. In this case, unless it’s a lighted switch, the switch is not an outlet and not required to be AFCI protected.
No, I don’t agree. An outlet is the point where current is taken, not the device/appliance itself. It is merely an opening in the system where current is taken. That is how I read it. It could be a ceiling box with a blank cover.
