Further, the switch body 2 includes a plurality of switch units arranged in a stacked manner, and the movable contact assemblies of the switch units are linked and rotated.

As shown in fig. 3 to 11, the operating device 1 includes an operating shaft 1131, a time-delay energy storage mechanism, a real-time energy storage mechanism, a locking mechanism and a tripping mechanism, which are rotatably disposed around their axes; the operating shaft 1131 rotates between an opening position and a closing position to output an opening and closing operating force to the real-time energy storage mechanism; the real-time energy storage mechanism comprises a second energy storage spring 1133, the operating shaft 1131 is in transmission fit with the real-time energy storage mechanism and is used for driving the second energy storage spring 1133 to store energy and release energy firstly so as to drive the operating device 1 to be switched between a switching-off state and a switching-on state, and the operating device 1 drives the switch body 2 to be switched on or off quickly; when the operating shaft 1131 rotates from the switching-on position to the switching-off position, the operating device 1 is driven by the real-time energy storage mechanism to be switched to the switching-off state, and when the operating shaft 1131 is switched from the switching-off position to the switching-on position, the operating device 1 is driven by the real-time energy storage mechanism to be switched to the switching-on state; the time-delay energy storage mechanism comprises a first energy storage spring 126, and the time-delay energy storage mechanism has an energy storage state in which the first energy storage spring 126 stores energy and an energy release state in which the first energy storage spring 126 releases energy; the locking mechanism is used for locking the delay energy storage mechanism in an energy storage state; the tripping mechanism is used for triggering the locking mechanism to be unlocked and matched with the time-delay energy storage mechanism, so that the time-delay energy storage mechanism releases energy, and the energy storage state is switched to the energy release state to drive the operating device 1 to be switched from the closing state to the opening state; when the operating shaft 1131 rotates from the opening position to the closing position, the delay energy storage mechanism is driven to be switched from the energy release state to the energy storage state, and the delay energy storage mechanism is locked with the locking mechanism to be locked in the energy storage state; when the delay energy storage mechanism is locked in the energy storage state by the locking mechanism, the operation shaft 1131 is avoided, namely, at the moment, the operation shaft 1131 rotates between the switching-on position and the switching-off position, and the state of the delay energy storage mechanism cannot be influenced.
