description This invention relates to an arc-free close or open outdoor vacuum switch matched with 72.50-500KV outdoor AC high voltage interface switches or an isolation switch having an earth device, in which, this invented on-off sensing current vacuum switch is composed of a vacuum switch mechanical control box and a vacuum switch, the vacuum switch set in a compound insulation sleeve is an upper static conduction contactor and a lower dynamic conduction contactor set in a vacuum chamber, the through end of the insulation sleeve of the upper static conduction contactor is set with a connecting board controlled by the mechanical control box together with the lower dynamic conduction contactor and connected to the earth end, which ensure safety operation of high voltage nets.
