or Fliehgewiohteyeterns, which are designed so that eioh the Forces acting in the upper speed range can still be controlled, in the lower Brehaahlbereioh the Centrifugal force must be too low to generate greater holding forces to be able to. In order to have at least sufficient switching * to achieve ways, scm can indeed the Pliehgewioht resp. let the refugee work against a white feather, dooh then the holding forces are at most enough to do the job Operation of loanable electrical switches and pneumatiaoh or hyarauliaohen control valves.

The invention is based on the task of building a centrifugal switch in a simple and operationally reliable manner, so that both at a certain lower masohine turning room and at a certain upper masohine turning speed} each. weils a shifting force is provided by at least 5kg at a satisfactory switching path, said Sohaltweg should be aurüokgelegt in each case with the smallest possible Drehzahldifferena. This object is achieved according to the invention in that the centrifugal switch consists of two tliehgewichtsysteaen seated on a common shaft and working separately via springs on a common sleeve, and that each of the two stop speeds of the machine is assigned to one of the two Fliehgewiohtsystema. In the case of the invention, the centrifugal force controller, the two borrowed systems differ from each other in terms of their holding activity. They work functionally independently of one another
