You can also remove the swith itself and turn it around if needed.
"SECRET" when installing a switch "off" should be toward the nose of the plane and "on" should be toward the tail.
The reason is simple. The wind flowing along the fuselage will help keep the switch turned on when flying and not trying to turn it off.
That must be some strong wind.

I do the same but just in case my hand brushes the switch as I release the plane. It will tend to turn "ON" instead of "OFF".
