ABSTRACT:
An actuation apparatus for a control switch which, in accordance with the position of a switching member, produces various control signals, in which an actuation arm coupled with the switching member is provided. The actuation arm is pivotable out of a central position of rest about a pivoting shaft counter to the restoring force of a torsion spring provided with free arms. A respective stationary initial stop is provided for each arm for the purpose of fixing the arm position in the position of rest and in which at least one coupler in contact with the free arms is connected with the actuation arm. At least one second stop, which acts as an end stop, is operatively associated with each free arm of the torsion spring to define the end of the switching paths.
