HIGH-VOLTAGE OR MEDIUM-VOLTAGE INSTALLATION

The invention relates to a high-voltage or medium-voltage switching system comprising at least one switching unit 1, which has a rotary switch 1A and a drive unit 10 for rotating the rotary switch, the drive unit 1 having a drive motor 9. The drive unit 1 has an actuation unit for actuating the drive motor 9, which is formed in such a way that when the drive motor 9 is operated the rotary switch 1A adopts a plurality of predetermined switching positions. The actuation unit has a switching member 17 for switching the drive motor 9 on and off and a rotatable body 16, as well as an activation element 18, which cooperates with the rotatable body 16, for activating the switching member 17. The activation element 18 and the switching member 17 ensure, together with the rotatable body 16, that the drive motor 9 is only switched on and off in particular rotational positions which correspond to particular switching positions of the switching unit 1, in such a way that the different switching positions can be approache
