When the operating device is in a switching-on state of a common side and is switched to a double-division position: as shown in fig. 24, the standby-side electromagnet 3' is energized, the iron core of the electromagnet 3' is connected with the standby-side electromagnet lever a04' to drive the standby-side turning lever a01' to rotate counterclockwise, and the standby-side turning lever a01' drives the common-side turning lever a01 to rotate counterclockwise through the connecting plate 2; or when the manual operation is carried out, the operating lever 6 is pulled from the opening K of the shell through the handle M, the operating lever 6 drives the rod connecting plate 2 to move towards the standby side, and the connecting plate 2 simultaneously drives the common side turning lever A01 and the standby side turning lever A01' to rotate anticlockwise. The corresponding main spring 4,4 'is rapidly contracted after reaching the maximum position along with the increasing of the rotation deformation of the corresponding common side turnover lever a01 and the standby side turnover lever a01', one end of the common side turnover lever a01 and one end of the standby side turnover lever a01 'drive the corresponding common side turnover lever a01 and standby side turnover lever a01' to continue to rotate anticlockwise until the standby side turnover lever a01 'contacts a turnover lever limiting bulge 102' arranged on the bracket 1, the other end of the common side main spring 4 drives the common side upper connecting rod B01 and the lower connecting rod B05 to turn upwards through the connecting pin shaft B02 until the upper connecting rod B01 contacts a limiting part 109 arranged on the bracket 1, the connecting pin shaft B02 is separated from the lower connecting rod sliding groove B0501 and continues to rotate to the lower connecting rod limiting bulge B0502, and the lower connecting rod B05 drives the main shaft B07 to rotate towards the double-split position through the connecting pin shaft three B06. And a first connecting pin shaft B02 'connected with the other end of the standby side main spring 4' slides to the bottom of a lower connecting rod sliding groove B0501 'of the standby side lower connecting rod B05' and then drives the standby side upper connecting rod B01 'and the standby side lower connecting rod B05' to overturn downwards, and meanwhile, the lower connecting rod B05 'drives the main shaft B07 to rotate towards a double-division position through a third connecting pin shaft B06'.

The corresponding connecting pin shafts three B06, B06' simultaneously drive the stop plate C01 to rotate until the double-positioning locking protrusion C0102 on the stop plate C01 is clamped on the double-positioning locking shaft C03, and then the double-positioning locking shaft reaches the double-positioning position. At this time, the standby side connecting pin shaft I B02' is continuously subjected to the acting force of the standby side main spring 4' to prevent the lower connecting rod B05' and the main shaft B07 from rotating towards the common side position, the corresponding indicating pieces D01 and D01' leave the upper side walls of the corresponding upper connecting rods B01 and B01', and the corresponding indicating pieces D01 and D01' display the opening state under the action of the corresponding indicating piece return springs D02 and D02' to be in the double-opening position as shown in the attached drawing 20.

When the switch operating device is switched from the normal side to the double-division position and is switched to the standby side: the unlocking electromagnet C02 is electrified to drive the bi-level locking shaft C03 to move downwards from the initial position through the via hole 106 on the bracket 1 until the bi-level locking protrusion C0102 on the stop plate C01 is disengaged. Or the handle M pulls the operating lever 6 from the opening K of the housing, and simultaneously the operating lever 6 drives the unlocking lever C04' to press the unlocking sliding plate C05 downwards, and the bi-component linkage arc-shaped hole C0502 on the unlocking sliding plate C05 presses the through hole 106 of the bi-component locking shaft C03 on the bracket 1 downwards from the initial position until the bi-component locking protrusion C0102 on the stop plate C01 is disengaged.

The standby side connecting pin shaft B02 'receives the acting force of the standby side main spring 4', and simultaneously drives the standby side upper connecting rod B01 'and the standby side lower connecting rod B05' to overturn downwards until the upper connecting rod B01 'contacts a limiting part 109' arranged on the support 1, at the moment, the switch operating device is in a standby side switching-on position state as shown in the attached drawing 25, and simultaneously, as shown in the attached drawing 21, the standby side upper connecting rod B01 'overcomes the acting force of an indicating piece reset spring D02' to link an indicating piece linkage part D010 'through an upper side wall so as to drive the indicating piece D01' to display a standby side switching-on power state, and the common side indicating piece reset spring D02 provides acting force for the common side indicating piece D01 to display a common side power switching-off state.

When the switch operation device is switched from the common side opening to the double-division position to the common side closing: when the operating device is in a state from a common side opening brake to a double-division position, the common side electromagnet 3 is electrified or the operating lever 6 is pulled to the common side to drive the common side turning lever A01 and the standby side turning lever A01' to rotate clockwise, the corresponding main spring 4,4' continuously increases along with the rotating deformation of the common side turning lever A01 and the standby side turning lever A01' and rapidly contracts after reaching the maximum position, one end of the corresponding main spring 4,4' drives the elastic common side turning lever A01 and the standby side turning lever A01' to continuously rotate clockwise until the common side turning lever A01 contacts the turning lever limiting bulge 102' arranged on the support 1, the other end of the common side main spring 4 drives the connecting pin B02 to rotate from the lower connecting rod limiting bulge B0502' on the lower connecting rod B05 to the lower connecting rod B0501 and slide into the lower connecting rod B0501 until reaching the bottom of the lower connecting rod B0501, and the connecting pin B02 drives the upper connecting pin B01 and the lower connecting rod B05 to be in a common side opening brake position when the common side brake is arranged on the upper connecting rod B0501.
