Abstract

The switch controlled by air flow is for the control of the electric supply to a fan blowing air into a car, as a function of its speed. The switch includes a pivoted flap subject to the opposing actions of the air flow produced by the movement of the vehicle, and the attraction of a magnet. Either of the two extreme positions of the flap are stable. The flap comprises two parts, the perforated flow sensing part and the magnetically attached part being at right angles to each other, and pivoted along the line where they join. Movement of the flap operates the switch which controls the ventilation of the car.
