ABSTRACT:
The switch element for triggering a cut off or control function is accommodated in a shaft (1), for example of a speed monitor. A spring-loaded release bolt (2) is surrounded coaxially by a compensating bush (4) which has a compensating ring (15), a spring plate (13) and a hub tube (14) and the center of gravity (S.sub.Kb) is such that, when the shaft (1) rotates, it compensates the centrifugal force, acting as an additional force to the spring prestressing force, of the spring half adjacent to the spring plate (13) and having the center of gravity (S.sub.F/2).
