摘要

Improvements in switches dependent on the number of revolutions with hysteresis between the disconnection and switching revolutions, characterized in that the housing is designed as a rotation body in such a way that it is divided into two concentric spaces, which are communicated by a an interstice extended all around such a height, that the mercury used as a charge, during its movement in a radially outward or inward direction, can circulate through this gap only under the action of an additional force, and the mercury thrown outward by the centrifugal force is impelled towards chambers of the rotating part (5) formed by elements in the form of a vane (5).
