FIELD: electricity.
SUBSTANCE: spring drive for an electrical switching device includes a closing spring device and an opening spring device. At least one of the spring devices includes torsion spring (3, 4) determining winding direction and unwinding direction. Torsion spring (3, 4) has a possibility of accumulating, storing and releasing mechanical energy. At least in one of the spring devices the torsion spring (3, 4) is set in the unwinding direction and actuated in the winding direction.
EFFECT: improving functioning reliability of a drive owing to increasing strength and simplifying connection of a torsion spring to the corresponding drive components.
