A switching mechanism for a gas insulated switchgear includes: a stationary contactor having a stationary arc contactor portion and a stationary main contactor portion; a movable arc contactor which is linearly movable; a movable main contactor which is linearly movable; a cylinder rod which provides driving power for linear motion to the movable main contactor and the movable arc contactor; a connecting rod which is connected to the cylinder rod; a stationary cylinder having a hollow guide tube portion for guiding the linear motion of the cylinder rod and the connecting rod; and a spring which charges elastic energy when the movable main contactor and the movable arc contactor move to the contacting position and discharge the elastic energy when the movable main contactor and the movable arc contactor move to the separating position.
