The invention relates to the field of new-energy electrical vehicles, and provides a manually maintained switch box for solving the problem that the safety is lower when a battery pack and a high-voltage power supply distribution system of an electrical vehicle are directly connected. The manually maintained switch box comprises a reversing switching unit and a movable control unit; the reversing switching unit comprises a switching box body and a switching box cover; the movable control unit comprises a switch shell, a plug arranged on the switch shell and a short-circuit protector arranged in the switch shell. According to the technical scheme, the function of effectively disconnecting or connecting a high-voltage power supply loop is achieved by quickly pulling out and plugging in the movable control unit; in addition, the manually maintained switch box has the good waterproof and dustproof effect and is suitable for a severe using environment.
