Abstract (en)

[origin: DE10006167A1] Power switch comprises an explosion chamber (2) with a driving linkage (4) which operates an operating pin (14) and nominal current contacts (11). The linkage is arranged so that at the start of the start of the disconnecting process the operating pin remains in a first dead center position until the nominal current path is broken. The operating pin is then moved into the switching direction at a higher average speed than the nominal current contacts which run against the ends of its disconnecting dispersion into a second dead center position. The operating pin reaches its disconnecting position only after the nominal current contacts have ended their disconnecting movement. Preferred Features - At the start of the switching process, the nominal current contacts remain in the second dead center position until the pre-ignition of the arc on closure is carried out.
