The invention provides a rapid-switch bistable state magnetic operating mechanism, and the operating mechanism comprises a moving core, a solenoid coil, permanent magnets, and a housing. The housing is a cylindrical housing, and the solenoid coil is disposed between a side surface of the moving coil and the housing. The permanent magnets comprise an upper permanent magnet and a lower permanent magnet, which are respectively disposed above and below the moving coil and have the opposite polarities. The magnetic core is provided with a guide column which is coaxial with the magnetic core. A switch can achieve the dual-holding and bistable state through the two permanent magnets when the switch is in any one state of switching-on or switching-off, thereby ironing out the defects that a conventional monostable permanent magnet mechanism is weak in holding force in a vacuum extinction chamber when the conventional monostable permanent magnet mechanism is in a switching-on or switching-off,and improving the overall reliability and stability of a rapid switch. Moreover, a spring tension structure in the conventional operating mechanism is simplified, and the switching performance of theswitch is greatly improved, wherein the switching-on time can be within 3ms. The mechanism has the good performances of high-speed switching and bistable state, and can achieve the electric switchingfunction through just changing the current direction of a coil.
