A switchgear driving arrangement includes a transmission element which penetrates a wall of a housing. The transmission element is guided in a linearly movable manner in such a way as to be supported on the wall. A first guide bearing is located inside the housing. A second guide bearing is located outside the housing. An electrical switchgear is also provided.

The present disclosure is directed to knob systems and methods to permit a smooth turning user input device that minimizes unintended horizontal displacement, along the X- or Y-axis, or unintended vertical displacement, along the Z-axis. The disclosed knob system may achieve this goal through the use of a back plate, a knob and a main housing extending through the knob and the back plate, the back plate comprises a plurality of Z-stop bearings, comprising a plurality of Z-stop balls and a plurality of Z-support springs, wherein the Z-stop bearings are in contact with the back plate and are configured to separate the knob from the back plate when the main housing is depressed in a vertical direction and wherein each of the plurality of Z-stop balls are attached to one of the plurality of Z-support springs, the Z-support springs bias the Z-stop ball against the knob.

The invention relates to a drive rod for driving a movable contact element of a high-voltage switching device, wherein said drive rod comprises a first section for connecting said drive rod to a drive mechanism, a second section for connecting said drive rod to said movable contact element, and an intermediate section between said first section and said second section, characterized in that said intermediate section comprises coupling means for rotatably coupling said first section to said second section.

A gear unit housing for a gear unit includes a two-sided control lever for moving two switching contacts of a circuit breaker in opposite directions. The gear unit housing includes a housing cassette having a housing base and a cover plate detachably connected to the housing cassette by screw connections and lying opposite to the housing base. A bearing shaft for mounting the control lever for rotation about the bearing shaft is connected to the housing cassette and to the cover plate and extends between the housing base and the cover plate. At least one stud element form-lockingly connects the housing cassette and the cover plate. A gear unit having the gear unit housing is also provided.

An electricity meter comprising an electrically-controlled electromechanical switch is disclosed. The electromechanical switch comprises a rotary actuator comprising a generally-cylindrical permanent magnet rotor having a central axis, a stator comprising a closed stator core and first and second opposite stator poles inwardly-projecting from the closed stator core towards the rotor and first and second coils wound around the first and second stator poles respectively. The electromechanical switch comprises a switch comprising at least one pair of first and second contacts wherein the first contact is movable. The electromechanical switch comprises mechanical linkage between the rotary actuator and the movable contact(s) configured such that rotation of the rotor from a first angular position to a second angular position causes the switch to be opened, and rotation from the second angular position to the first angular position causes the switch to be closed.

The invention relates to a drive rod for driving a movable contact element of a high-voltage switching device, wherein said drive rod comprises a first section for connecting said drive rod to a drive mechanism, a second section for connecting said drive rod to said movable contact element, and an intermediate section between said first section and said second section, characterized in that said intermediate section comprises coupling means for rotatably coupling said first section to said second section.
