High -voltage switch

The utility model provides a high -voltage switch includes frame and isolator, vacuum switch and the earthing switch of setting in the frame, and isolator realizes opening and shutting through the swing of keeping apart the swing arm, and vacuum switch realizes opening and shutting through the removal of moving contact, and earthing switch realizes opening and shutting through the swing of groundconnection floodgate. High -voltage switch's operating mechanism includes first input shaft, second input shaft and third input shaft, and the swing arm is kept apart in the linkage of first input shaft, second input shaft linkage moving contact, third input shaft linkage ground connection floodgate. Operating personnel is to the drive operation mutual independence of first input shaft, second input shaft and third input shaft. Consequently operating personnel can distinguish switch that the input shaft corresponds the very first time and operate the input shaft, and the operation of this input shaft does not form the
