The utility model provides an electromagnetic switch self-locking device, comprising a movable iron core, a keeper, and a fixing base. The fixing base is provided with a movable locking piece with an elastic part, one end of which is withstanding the fixing base, and the other end is withstanding the locking piece. When the locking piece moves forward under the action of the elastic part, the lock-tongue will prevent the movable iron core or the keeper from moving downward, and make the movable iron core or the keeper unmovable. Only if an external force is exerted on the locking piece to overcome the elastic force of the elastic part and make the locking piece move backwards, the lock-tongue can be detached from the movable iron core or the keeper, and the movable iron core or the keeper becomes movable.
