| description | According to the switch device with the false closing prevention structure, the worm gear and the worm drive structure with the back locking function respectively drive the wiring knife switch and the grounding knife switch to conduct opening and closing work, so that stable control over the opening and closing processes of the wiring knife switch and the grounding knife switch is achieved, and the false closing prevention structure is achieved through cooperation of the controller, the clutch assembly and the drive assembly. The switch-on indication assembly can be used for indicating the switch-on state of the wiring disconnecting link and the switch-on state of the grounding disconnecting link through the indicating lamp set, and the switch-on state of the wiring disconnecting link and the switch-on state of the grounding disconnecting link are displayed through the indicating lamp set. A worker can judge the working progress of the disconnecting switch according to the indicator light and the controller a |
