A spindle drive for generating a rotational motion, in particular a drive for a high-voltage disconnecting switch, includes a drive shaft, at least one sliding block disk being mounted on the drive shaft and having recesses formed therein, two retaining bolts, a carriage in which the retaining bolts are fastened, a single slide nut for moving the carriage, and a drive spindle for moving the retaining bolts into engagement with the recesses. The drive spindle moves the retaining bolts through the slide nut and the carriage.

Spindle drive

A switch drive assembly includes a switch having a contact and a control shaft for actuating the contact and switching substantially currentlessly, and a drive having a drive motor, a flywheel accumulator connected to the drive motor for receiving a change from the drive motor immediately prior to a switching process, the flywheel accumulator being coupled to the control shaft for discharging during a switching process and executing a previously initiated switching process, the drive motor acting as a generator for generation of a self-sufficient voltage supply during discharge of the flywheel accumulator.
