A steering device which is configured as a steer-by-wire steering device includes a steering shaft disposed for rotation in a circumferential direction, a casing tube at least partially encompassing the steering shaft where the steering shaft is fixed in relation to the casing tube in an axial direction of the steering shaft, a sleeve encompassing the steering shaft, and a locking device. The steering shaft has an external thread which meshes with an internal thread of the sleeve. The sleeve is form-fitted into the casing tube such that the sleeve is displaceable in relation to the casing tube in the axial direction and is fixed in the circumferential direction. A lateral surface of the sleeve has a recess. The locking device and the recess are disposed such that the locking device is engageable into the recess in an axial position of the sleeve.

A switching device arrangement has an encapsulation housing and also a drive device. The drive device is supported on the encapsulation housing. The drive device is arranged at a distance from the encapsulation housing via a spacer device. A receiving space is delimited by the spacer device.

Switching device arrangement

A snap-action drive for a switching device has an energy store, a swinging movable part and a securing device for the movable part. The securing device secures a position of the swinging movable part by a force effect, wherein a reversal of direction of the movable part takes place counter to the force effect.

An electrical switching device has a state indicator which is covered or uncovered in accordance with the state of the switching device. In order to reduce the amount of moved masses, the state indicator remains in a resting position during a switching process of the electrical switching device. The state indicator can be covered at least in part by the movable switching contact pieces of the electrical switching device, for example.

Apparatus for monitoring the state of an electrical switching device

In an arrangement comprising at least one operating unit of a camshaft adjusting device for an internal combustion engine, the operating unit and at least one ventilation unit of a ventilation device are combined in an assembly module.

Device comprising at least one functional unit of a camshaft adjusting device

In a camshaft adjuster having a 4/2-way valve which rotates with the camshaft and includes a hydraulic control valve with a hydraulic control spool or piston, which is actuated in a control cylinder against the force of a compression spring between two end stops by a magnet armature of an electromagnet which is fastened to a control casing, the electromagnet is a repelling proportional magnet, whose magnet armature is seated fixedly on an armature plunger whose free end face is in contact with the control spool or with a part fixedly connected to the latter for moving the control spool against the force of the compression spring to actuate the hydraulic control valve so as to control fluid admission to the camshaft adjuster, the working stroke of the electromagnet exceeding that of the control spool.
