The invention provides a manual safety switch for an electric switch machine. The manual safety switch comprises a manual rod, a limiting movable plug frame, a static plug frame and a connecting rod mechanism. A static plug group is assembled on the static plug frame, and the static plug frame is fixedly connected with a bottom shell; a safety contact group is assembled on the limiting movable plug frame; a static contact piece of the static plug group corresponds to a movable contact ring of a safe power connection group in position; the limiting movable plug frame is connected with a manualrod, the manual rod penetrates through the bottom shell, the manual rod drives the limiting movable plug frame to move, and the connection and disconnection of the movable contact ring and the staticcontact piece are achieved. The limiting movable plug frame is connected with a baffle plate through a connecting rod mechanism. According to the invention, the manual rod is rotated through a specialwrench, so that the switching between disconnection and connection of the safety contact is realized, and the reliability of the manual safety contact is ensured.
