Narrative:
Trying to turn panel lighting off when smoke erupted from knob that was being turned. Light smoke with electrical smell was visible about 1 minute after occurrence and elected to proceed back to the ramp. No other smoke was indicated on the 3 minute taxi back to the ramp. Aircraft engine was shut down and aircraft parked with no fire or burnt wire being noted. Fire trucks were standing by. What caused the problem I believe was the knob not being used in years and the switch being overworked. To prevent a recurrence would be to not move the knob as well as having the knob and electrical wiring repaired and to working order. Also; to use the checklist and to evacuate if the need arises.
