摘要：
A vacuum exhaust element (30) of a vacuum switch in which a vacuum vessel (2) and a power source circuit (34) are grounded to always have zero potential, so that the vacuum exhaust element (30) does not need a withstand voltage in which a high voltage is taken into account to allow the vacuum exhaust element (30) to have an ordinary withstand voltage, and so that the vacuum exhaust element (30) can be miniaturized, and it is safe for a worker to touch the vacuum vessel (2) and the vacuum exhaust element (30) when the worker carries out maintenance/inspection.
