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.

A device that is placed between the electrical power source and electrical equipment such that power going to the equipment can be controlled, regulated, and monitored. An individual may request access to use the electrical equipment by means of unique identification. The device is able to compare the user's request for authentication via a locally stored list (database) or remotely situated list. The device contains audio and visual indications of the current status of power going to the electrical device. An apparatus is used to prevent a user from disconnecting electrical equipment from the device and reconnecting it directly to the power source. A related method of use is also claimed.

An article for securing and ordering cables leading away from a key switch comprises an annular fastening section with an opening, wherein a lock cylinder of the key switch extends through the opening. The article further comprises a plastically deformable cable receiving section which is connected with the fastening section and which can be bent around the cable and thus encircle the cable.

An ignition key switch apparatus having a compact size, high current capability, and a snap action mechanism. A pre-loaded snap spring can be configured to include a fixed end attached to an anchor and a free end attached to a movable contact operable between normal and actuated positions. A cam can be utilized to convert a rotary motion at a key interface into a linear movement of a plunger for snap spring blade actuation. The unique pre-loaded snap spring generates a fast (e.g., instantaneous) movement from an open to a closed position and vice versa upon application/removal of a load to reduce the effect of arcing on associated contacts and conductors. The pre-loaded snap spring also ensures that the movable contact does not remain in any intermittent position, other than the two extreme positions given at any position of the plunger.

A push button actuator unit has a housing that defines a passage extending along an axis. A push button assembly has components movable in the passage including a forwardly-biased push button at the front of the housing that is movable along and turnable about the axis. Two independently movable operating elements at the rear of the housing move differently in response to depression of the push button when the push button is turned to different orientations about the axis. The rear operating elements may extend concentrically along the axis, and the unit may be lockable to permit and prevent some operating element movement. The operating elements may be used to selectively disengage, or to engage and move a variety of auxiliary devices situated behind the unit. The unit may provide enhanced resistance to defeat by hammering than has been offered by a known form of push button unit.

An assembling structure of a quick installation/uninstallation switch, including a layout fixing seat formed with a central opening and a transverse insertion slot intersecting the central opening. A locating member is inserted through the transverse insertion slot. The locating member is formed with a central hole corresponding to the central opening. A resilient locating member and at least one lateral projecting section with a guide slope are disposed on the circumference of the central hole. At least one resilient restoring member is disposed between the locating member and the layout fixing seat for restoring the locating member to its home position. A connecting end of a switch main body is fitted in the central opening. A lateral locating section with a guide slope is formed on a circumference of the connecting end corresponding to the lateral projecting section. A locating transverse slot is formed on the circumference of the connecting end. The resilient locating member is inlaid in the locating transverse slot.

A cylinder lock monitoring assembly for monitoring position of a lock cylinder. The monitoring assembly includes a housing having an inner cavity and an exterior diameter. The exterior diameter of the housing is not significantly greater than the corresponding cylinder diameter. The assembly further includes a switch received into the inner cavity of the housing. The switch is in electrical communication with an indicator. The switch is reactive to any change in position of the lock cylinder.

A switch device for key operation includes a housing having a receiving recess at an inner bottom face of which an electrode pattern is disposed, a rotary holder rotatably disposed in the receiving recess to hold at least two movable contact members that are brought close to or separated from the electrode pattern, a bottomed recess formed in the rotary holder along its rotation axis, a slider disposed in a slidingly movable manner in the bottomed recess, a spring disposed within the bottomed recess so as to bias the slider in a direction opposite to an insertion direction of an external key when the external key is inserted into the bottomed recess, and a case having an opening allowing the slider to be exposed therethrough, and attached to the housing so as to cover the receiving recess. The at least two movable contact members respectively have extending pieces that extend into the bottomed recess. An intermediate connecting member that comes into resilient contact with each of the extending pieces, and slides when the external key is inserted into the bottomed recess is disposed in the slider.

It is an object of the invention to provide the operability of an engine power generator having a remote controller. A starting switch 90 of a remote controller 9 and a starting switch on a power generator body's side can be operated in parallel. A stopping switch 91 of the remote controller 9 and a stopping switch on the body's side can be operated in parallel. The stopping switch 91 and an oil level switch 26 are connected to each other in parallel. The starting switch 90 and the stopping switch 91 can be operated when a combination switch 12 is in ON position. An engine 2 can be started and stopped by switching operation on the body's side in parallel to remote control operation.
