The switch consisted of a spring assisted (off) 3 inch by half inch wide arm that would fold back at apx. 30 - 80 K (never ran along side to check). When the flight was over, the arm would trip the switch off when the airspeed was reduced upon landing. With the reduction of slip stream air pressure on the arm, the spring would move it down and away from the tucked in position to the off position. For IFR operations, it was not uncommon to sit at the runup apron and wait 20 - 30 minutes for clearances. That amount of time can add up after a while.
