The invention discloses a sequential waveguide switch drive device and relates to the field of microwave switches. The sequential waveguide switch drive device comprises a stator, a rotor, internal teeth, copper coils and a lock structure, wherein the stator is of a ring structure; the rotor is of a gear-like structure; the rotor is fixedly arranged at the center position of the stator; the innerwall of the stator is symmetrically provided with protruding internal teeth along the diameter direction; the rotor is located between the two internal teeth; each copper coil is wound on the outer wall of the corresponding internal tooth; the lock structure comprises an upper magnetic steel group and a lower magnetic steel group; the upper magnetic steel group is arranged at the lower end of thestator and the distance between the upper surface of the upper magnetic steel group and the lower surface of the stator is 8-12mm; and the lower magnetic steel group is arranged at the lower end of the upper magnetic steel group and the distance between the lower magnetic steel group and the upper magnetic steel group is 0.8-1.5mm. According to the sequential waveguide switch drive device, a radiofrequency system ''reaches'' the specified state and the radio frequency system is also stabilized in the specified state.
