The utility model discloses a novel three-electrode gas spark switch which comprises a switch anode, a swing rod, a switch cathode and a telescopic driving mechanism, the swing rod is vertically installed above the switch anode, and the upper end of the swing rod is hinged to the driving end of the telescopic driving mechanism. An intermediate electrode is arranged in the swing rod in a penetrating manner, the lower end part of the intermediate electrode is arranged close to the upper end part of the switch anode, the switch cathode transversely and movably penetrates from the side wall of the swing rod and is electrically connected with the intermediate electrode, and the telescopic driving mechanism drives the swing rod to swing back and forth by taking the switch cathode as a rotating shaft point during operation. The utility model has the advantages of simple structure, simple control, reliable operation, long service life, short switch discharge time and extremely small breakdown gap, realizes switching
