ABSTRACT OF THE DISCLOSURE Disclosed is a power drive for electric switchgear in which the driving force is elastically transmitted to an actuating member, for example, a handle. Thereby, tolerance compensation is provided to allow the drive motor to run into the end positions of the drive. A bending-type spring is disclosed as an elastic power transmitting member which is arranged transversely to the direction of motion of a slide which transmits the driving force to the switch- gear. The bending-type spring can be connected to the slide. The bending-type spring can be a leaf spring, and more particularly two parallel leaf springs. In the disclosed embodiments, the two parallel leaf springs are provided as a single U-shaped leaf spring having parallel legs. The U-shaped leaf spring can either be supported at both ends thereof in the slide or the legs can be fasten- ed in a mounting body connected to the slide.
