The present invention provides an isolation switch, belonging to the technical field of electrical devices. The problem is solved that a current isolation switch is easy to generate arc when switch-onand is unstable in current after closing. The isolation switch comprises a pedestal, a first post insulator, a second post insulator, a first wiring plate and a second wiring plate which are respectively arranged on the first post insulator and the second post insulator, and a left blade and a right blade which are hinged on the first wiring plate. The left blade and the right blade are respectively provided with movable contacts, a gap is arranged between the movable contacts, the second wiring plate is provided with a static contact, the static contact has two butting surfaces, a distance between the two butting surfaces is gradually reduced along the bottom portion of the static contact in a head portion direction, and when the left blade and the right blade are closed, the static contact can be laid into the
