The invention discloses a two-station switch for a gas-insulated metal-enclosed switchgear, and belongs to the technical field of medium-pressure gas-insulated metal-enclosed switchgear. The two-station switch comprises a gas tank, a movable contact, a static contact, an insulation main shaft and an operation mechanism, wherein the movable contact and the static contact are arranged in the gas tank, the insulation main shaft is rotatably arranged in the gas tank, the movable contact is fixedly arranged on the insulation main shaft, the static contact comprises a static contact connected with amain loop and a static contact connected with a grounding loop, and the insulation main shaft rotates under driving of the operation mechanism so that the movable contact is connected with the staticcontact connected with the main loop or is connected with the static contact connected with the grounding loop. The two-station switch is arranged in the medium-pressure gas-insulated metal-enclosedswitchgear, the main loop or the grounding loop is connected, the situation that a main voltage transformer connected with the main loop is needed to be disassembled during insulation test by an existing connection mode is prevented, and the situation that the main loop is needed to be powered off during replacement and maintenance of the voltage transformer is prevented.
