The shift transmission a multiple-speed draw key transmission, having a draw key that, in different positions, establishes different transmission ratios between the input shaft and an output shaft of the shift transmission, wherein the draw key is connected to a centrifugal force regulator that shifts the draw key in dependence on a rotational speed of the input shaft or a rotational speed of the output shaft.
