Patent ID: 6855902

Claim:
A self bouncing arc switch, comprising: an inner electrode ( 1 ), having two ends, fitted around a central shaft and cylindrically disposed around the central shaft; an outer electrode ( 2 ), having two ends, arranged to be concentric with said inner electrode and spaced apart from an outer surface of said inner electrode, to form a spacing unit ( 11 ) between said inner and outer electrodes; one or more arc working gas ports ( 8 ) for injecting arc working gas into the spacing unit, such that a switching arc makes electrical contact between said inner and outer electrodes axially or circumferentially, and for evacuating injected arc working gas; one or more trigger electrodes ( 9 ) each disposed between one end of said inner electrode and one end of said outer electrode, to breakdown the arc working gas and initiate the switching arc; an inner conductor ( 2 a ), extending outwardly from both ends of said outer electrode, arranged to be spaced apart from an outer surface of said outer electrode; an outer conductor ( 1 a ), extending outwardly from both ends of said inner electrode to cover the outer surface of said inner conductor with a first insulation layer ( 5 ) interposed between said inner and outer conductors; and one or more terminals ( 10 ), leaded at each end of said inner and outer conductors, for connecting said inner and outer conductors to external circuitry.
