Abstract: A plug-in connection includes a first and second coupling part. The first coupling part includes a first contact element, an electrical cable, an insulation sleeve, and a first housing. The first contact element includes a base region and an outer region with an edge region, an external shell surface, and a slot. The electrical cable includes an electrical conductor, a connection region, and an insulation for the electrical conductor. The insulation sleeve surrounds the outer region and includes an external and internal shell surface. The first housing surrounds the base region, the insulation sleeve's external shell surface, and the connection region. The second coupling part includes a second contact element with an external shell surface over which the first contact element's outer region is slidable, and a second housing which encloses the second contact element and together therewith forms an annular space into which the first housing is insertable.

Abstract: An electrical plug apparatus for establishing an electrical connection by mating with a mating plug apparatus includes a housing, an electrical feed line comprising an insulating sheath, and at least one electrical contact element comprising a first end and a second end. The first end is in contact with the electrical feed line. The second end leads in a plugging direction, and is mounted in the housing and configured so as to move perpendicular to the plugging direction under an effect of an electrical mating contact element of the mating plug apparatus bearing against the second end. The at least one electrical contact element comprises a material which allows an elastic deformation movement as an effect of the electrical mating plug element.

Abstract: A joystick (100), with first means for the mounting of a stick (1) and for bringing about forces against tilting of the stick (1) at least about a certain axis, said means comprising a stick (1) with at least one projection (2) which extends in the longitudinal direction of the stick (1) and has the outline of a semicircle reduced by half the thickness of the stick (1) and is guided in a sliding manner in a groove which is matched to the shape of the projection (2) and is provided in at least one movement module (4), which is mounted rotatably in a housing (9) of the joystick (100), with an axis of rotation.

Abstract: A controller controlling the drive mechanism of a powered industrial truck has two Hall effect sensors, which are located at a lateral distance from one another, and a source of lines of magnetic flux, which can be displaced relative to the Hall effect sensors when the controller is actuated, so that the magnetic flux density changes in the Hall effect sensors.

Abstract: A tiller head with a switch arrangement for operating a lifting mechanism of a forklift includes an operating element mounted on the tiller head, where the operating element has an actuator, and a magnetic field sensor operatively connected with the actuator without contact so that the magnetic field sensor's electrical characteristic varies when the operating element is actuated. The actuator includes magnetic field sources arranged on both sides of the magnetic field sensor, the magnetic field sensor and the magnetic field sources being arranged so that magnetic field lines generated by the magnetic field sources pass through the magnetic field sensor. The operating element comprises a rocker switch that pivots about an axis on the tiller head, the rocker switch having a recess which extends transversely to an operating direction defined by the axis and into which the magnetic sensor extends.

Abstract: An electrical plug connection for connecting a consumer or a charging device to a battery. The plug connection includes a plug part and a socket part. The part of the plug connection located on the battery side is provided with a transponder (15) in which data suitable for identifying the battery is stored.
