FIELD: machine building.
SUBSTANCE: invention refers to a drive mechanism. A drive mechanism for a medium voltage fuse switch comprises a base plate (10) and a front plate (11) which form an inner space enveloping a working shaft and a driving shaft set coaxially along the first longitudinal axis, the driving shaft is functionally coupled with a kinematic circuit of the medium voltage fuse switch, the working shaft (20) is fitted by a head connected to an operating handle for manual actuation of the working shaft, a spring unit consisting of two spiral springs having the first end functionally coupled with the working shaft, a clamping unit consisting of two clamping tabs set on the driving shaft, the first (61) and the second (62) unclamping units to unclamp the driving shaft and provide for its rotation. The first unclamping unit (61) provides for the rotation of the driving shaft in the direction opposite to the second unclamping unit (62).
EFFECT: reduced manufacturing, mounting and operational costs.
