In time, those switch contacts wear.
You can check the other switches out by turning all 6 bulbs on.
After about 10 minutes, "gently" turn the switch knob "backwards".
If that causes the lights to flicker, then that says that switch has reached it's useful life, and should also be replaced.
Those switches are special to Airstream, and can be obtained from parts stocking dealers.
