Abstract
A hybrid switch assembly is provided for a vacuum switch, such as for example a vacuum interrupter. The vacuum interrupter includes a vacuum envelope, a fixed contact assembly partially within the vacuum envelope, and a movable contact assembly partially within the vacuum envelope and movable between a closed position in electrical contact with the fixed contact assembly and an open position spaced apart from the fixed contact assembly. The hybrid switch assembly includes at least one radial magnetic field generating mechanism, such as for example a spiral contact or cup member, and a number of axial magnetic field generating mechanisms each comprising a ferromagnetic or ferrimagnetic member, such as for example, a horseshoe plate assembly. Each axial magnetic field generating mechanism is disposed within the vacuum envelope proximate a corresponding radial magnetic field generating mechanism.
