ABSTRACT:
In a variable inductor of the type comprising a helical winding, the pressure exerted by the slider on the conductor of the winding decreases when the slider undergoes a high-speed displacement. A separating device is associated with the slider and, under the action of the centrifugal force produced at the time of a high-speed displacement of the slider, tends to move said slider away from its point of application on the conductor and therefore to reduce the pressure at the point of contact between the slider and the conductor. Wear resulting from displacements of the slider is thus minimized.
