A stator device for a linear motor comprises an electrically energizable magnetic field generator for forming a magnetic field, the magnetic field generator comprising a stator tooth and a coil wound around the stator tooth and a holding module for holding the magnetic field generator, the holding module having a first and a second holding device, wherein the magnetic field generator is arranged between the two holding devices in that a first end of the stator tooth is fixed to the first holding device and a second end of the stator tooth is fixed to the second holding device.

A switch disconnector comprises an electrical contact system for breaking a circuit connectable to the switch and a ferromagnetic plate being positioned in a predefined distance to the electric contact system, wherein the predefined distance is selected such that the magnetizing force of the ferromagnetic plate on an electric arc occurring between separated contacts of the electric contact system pulls the arc onto the ferromagnetic plate for interruption of the arc.

A circuit interrupter having at least two sets of contacts that are electrically connected in series such that when the at least two sets of contacts are opened, they are opened simultaneously. This functions to increase the distance between the sets of contacts as the distance is additive for the series connected sets of contacts, which increases the arc voltage for breaking any arc that may form between the individual sets of contacts more effectively.

A contact device includes: a contact block including a plurality of fixed terminals on which fixed contacts are formed, and a movable contactor on which movable contacts contacting and leaving the fixed contacts are formed; and a driving block that drives the movable contactor. Moreover, it is made possible to extinguish arcs, which are generated in an event where the contacts contact and leave each other, by arranging permanent magnets on a periphery of the contact block. Then, at least one fixed terminal among the plurality of fixed terminals is formed so that the fixed contact and the movable contact can abut against each other in a region other than a side opposite to the other fixed terminal.

An electrical switch including a frame, an operating shaft, and a bridge member movable in a depth direction relative to the frame by rotation of the operating shaft, wherein the depth direction is parallel with a rotation axis of the operating shaft, and wherein the operating shaft is adapted to exert a first opening force to the bridge member during an opening event. The electrical switch includes an anti-tilting member movable in a lateral direction relative to the frame by rotation of the operating shaft, the lateral direction being perpendicular to the depth direction, wherein the anti-tilting member is adapted to exert a second opening force to the bridge member during the opening event, the second opening force being parallel to the first opening force and spaced apart from it in the lateral direction.
