Date Feb. 23, 1995A drive for an electric high voltage circuit-breaker has a revolving crank that is driven by an energy storage mechanism, such as a spring, between an upper dead center and a bottom dead center and a backstop that prevents the crank from moving backwards against the driving direction after it moves beyond the bottom dead center. The backstop is provided with a friction clutch with a first ring that is firmly coupled to the crank and the driving shaft and that can rotate in relation to a second return stop ring when a releasing force is exceeded.
