Electrical Code Clarification
The switch location is not an outlet according to NEC, unless you're installing a switch/ receptacle combo device.


  Outlet. A point on the wiring system at which current is taken to supply utilization equipment.


I doubt an inspector would require the circuit to be AFCI protected, but ultimately that's who'll make the final decision.  To be sure, contact your local electrical inspector.

That being said... AFCI protection is designed to help protect you and your home, so it's not a bad idea to protect the circuit even if it's not required.
