Abstract: PROBLEM TO BE SOLVED: To provide a grounding switching device which can share potential by means of a vacuum gap and an air gap and has a duty for closing short circuit. SOLUTION: The grounding switching device has a primary circuit conductor 1 of a switch gear, a grounding electrode 15 which becomes a grounding point of the primary circuit conductor 1, and a vacuum valve 4 with a pair of vacuum contacts 2, 3 which turn between the primary circuit conductor 1 and the grounding electrode 15 and which can come in contact with each other and separate from each other. The air gap is formed with a first air contact 11 fixed on a movable side of at least the vacuum valve 4 and a second air contact 16 arranged on the grounding electrode 15 by turning the vacuum valve 4.
