| 摘要 | The invention relates to a locking device for a drive unit for actuating a connection device of a switching assembly, said locking device comprising a spindle drive for actuating the connection device and a gear mechanism which is coupled or can be coupled thereto, and can be driven by a drive motor (320) or by a manually operated device, and after a defined number of partial rotations of a drive shaft connected to the gear mechanism, of the spindle arrangement, the connection device locks so that said connection device is brought into a predefined position or into a switch position and displays the position using provided position display modules. The number of partial rotations for locking the connection device is either larger or smaller than a complete rotation of the drive shaft and if the defined number of rotations is not reached, the position or switch position is not displayed by the position display module. | ||||||
