[0039] Working principle: the embodiment provides a linkage switching of reclosing switch, when using,

[0040] In the switching-off state: the tongue plate 1114 is deflected by the switching-off handle assembly 9 to make the clamping block 1112 separate from the clamping groove 1202, and the initial unlocking is completed, when the tongue plate 1114 is deflected, the connecting arm 1111 is deflected around the support 1110 to make the clamping block 1112 separate from the clamping groove 1202, and the pushing block 1115 exerts a pushing force on the protruding block 1116 to deflect the linkage disc 1201, thereby making the strip-shaped protrusion 1127 separate from the anti-separation groove 1305, and the further unlocking is completed, so that the permanent magnetic slide 1125 can be controlled by the electromagnetic coil 1129 to complete the switching-off action;

[0041] In the closed state, electromagnetic force is generated by energizing the electromagnetic coil 1129, thereby generating suction force on the permanent magnet slide 1125, so that the permanent magnet slide 1125 is acted upon by the electromagnetic force and rises, thereby driving the actuator rod 1128 and the movable seat 1126 to rise.
