Zusammenfassung: | The utility model relates to an isolating switch operating mechanism and a double-confirmation device thereof. A double-confirmation device of an isolating switch operating mechanism comprises an auxiliary switch mounting frame and a transmission arm, two auxiliary switches are mounted on the auxiliary switch mounting frame and connected with crank arms respectively, the two crank arms are connected through a linkage arm, so that synchronous action of the two auxiliary switches is achieved, and the transmission arm moves linearly to drive the linkage arm to reciprocate. The device further comprises a microswitch installation frame, and two microswitches are installed on the microswitch installation frame. A triggering piece is fixed to the transmission arm, the triggering parts of the two microswitches are located on the two sides of the triggering piece in the movement direction of the transmission arm, and when the transmission arm moves in the axial direction of the transmission arm, the triggering piece i |
