The invention discloses a
waveguide switch with a novel structure, which comprises a control device and a rotor
assembly, a control rotating shaft of the control device is connected with a motor shifting block, the motor shifting block is provided with a
slip ring, a rotor rotating shaft of the rotor
assembly is connected with a rotor shifting block, and the
slip ring is slidably clamped in a chute of the rotor shifting block. According to the
waveguide switch, the 90-degree special
micromotor is matched with the rocker sliding block transmission mechanism, 90-degree reciprocating rotation of the motor is converted into 90-degree rotation of the rotor, and four-channel corner
cut conversion is achieved; a manual switching mechanism is designed to meet the requirement of manual control in the mechanical
assembly and joint test process, and dual control of
electric control and manual control is achieved; and after setting in place, an automatic power-off measure ensures the safety of the
waveguide switch. According to the waveguide switch, the complexity of a
control circuit is reduced, the
insertion loss is small, the isolation degree is high, the bearing power is large, the performance is stable and reliable, and the safety is high.
