Japanese Patent JPS5319104
Kind Code:
B2
Abstract:
A vacuum switch has a pair of disk shaped switching contacts relatively separably located in an evacuated housing with one of the contacts attached to a central electrically conductive supporting member surrounded coaxially by a coil in electrically parallel relation to the supporting member at the switching contact, and the coil is connected to areas of the contact separated from the central portion of the contact by an at least partial separation in the form of a ring-shaped groove or complete annular separation, thus equipping the switch for very high cut-off electrical currents.
