摘要： An electric centrifugal switch is proposed, in particular for the purpose of safety shutoff upon attainment of a shutoff rpm for fuel injection systems, electrically controlled in an open- or closed-loop manner, of internal combustion engines, which is not vulnerable to rotary oscillations and which effects a rapid shutoff. The centrifugal switch comprises a centrifugal pendulum secured by means of a metal band bearing on a revolving carrier element and a switch attached to the housing and provided with a switching distance from an actuation pin. The centrifugal pendulum carries a flyweight mass on the end of a first lever arm extending substantially in the direction of the rotary axis, and its second lever arm extending at least approximately rectangularly to the rotary axis, is held together with a metal band of the band bearing in constant contact on a roll-off surface located on the carrier element by a restoring spring and, in a preferred embodiment, by means of a supplementary spring element. The inclination and spring rate of the obliquely positioned restoring spring are so designed that the increase in spring force when the centrifugal pendulum is swinging outward is less than the corresponding increase in centrifugal force.
