An ignition lock for a motor vehicle includes a locking cylinder, which in the presence of a suitable key can be shifted along a path including a punctual directional change between a driving position and a stationary position. In the driving position the ignition lock allows operation of an engine of the motor vehicle. In the stationary position operation of the engine is blocked. An indicating device is controlled by a switch operable by the locking cylinder at the point of directional change.

A wind turbine having a nacelle with a stationary region and a rotor, at least one blocking unit for blocking the rotor, and an access control system is provided. The access control system controls a locking of at least one access door to at least one closed-off region in the wind turbine depending on a blocking of the rotor by means of the least one blocking unit. The access control system has a key transfer system and a hydraulic control unit for controlling the blocking unit. The key transfer system has a hydraulic key unit for preventing an unintentional activation of the hydraulic unit and an access door key unit for locking or unlocking the access door. The key transfer system has at least one first and second key, the hydraulic control unit being locked or unlocked by means of the first key, and the access door key unit being locked or unlocked by means of the second key, and the key transfer system also having a fan key unit for activating or deactivating a fan, the first key of the hydraulic key unit being used to lock and unlock the fan key unit and a fan key being used as a second key for locking or unlocking the access door key unit.

The device is used for locking an access for actuating two switching devices of high-voltage switchgear with the aid of a drive shaft transmitting drive force onto the two switching devices. In order to increase the operational safety of the high-voltage switchgear with little outlay, the locking device comprises a closing disk which is fastened on the drive shaft, a rocker bar arrangement containing at least four rocker bars, and a slider. The slider can be moved, on-site, into two positions, the first of which releases an access for the actuation on-site and blocks an access for the actuation from a remote location, and the second of which blocks the access for the on-site actuation and releases the access for the remote actuation.
