s1: when the switch-on is used, the push plate (2012) on the right side is pushed to drive the moving rod (2011) to go deep into the shell (2), the first elastic element (2013) contracts, the bottom of the moving rod (2011) on the right side extrudes the swinging rod (401), the swinging rod (401) rotates clockwise around the rotating shaft (4), the right end of the swinging rod (401) descends, the second inclined surface (4021) of the force-bearing block (402) on the outer side of the swinging rod (401) extrudes the first inclined surface (3032) on the outer side of the push block (303), the second elastic element (302) contracts and stores energy, along with the continuous acting force on the push plate (2012), the central line of the force-bearing block (402) crosses the middle part of the bottom side of the push block (303), namely after an inflection point passes, the force on the push plate (2011) is removed, and the first elastic element (2013) recovers and drives the moving rod (2011) to move towards the outer side of the shell (2), after energy storage, the second elastic element (302) restores to deform and enables the first inclined surface (3032) to extrude the second inclined surface (4021), the force-bearing block (402) drives the swinging rod (401) to rotate, and then the driving head (403) on the outer side of the swinging rod (401) is abutted against the switch contact actuator (1012), so that the switch-on operation of the switch contact actuator (1012) is rapid;
s2: when the swing rod (401) rotates by taking the rotating shaft (4) as a circle center, the swing rod (401) drives the U-shaped plate (5) on the outer side to rotate clockwise;
s3: the U-shaped plate (5) is deflected, the guide rod (602) rotates anticlockwise, the fixed shaft (501) in the U-shaped plate (5) slides relatively in the guide groove (6021) of the guide rod (602), the fixed shaft (501) presses the second fixing ring (6023), the third elastic element (6024) is contracted until the U-shaped plate (5) and the guide rod (602) cross a dead point, the third elastic element (6024) recovers after energy storage and deforms to further push the swing rod (401) to rotate clockwise, a double energy storage boosting effect is formed, the rotation power of the swing rod (401) is higher, the left push plate (2012) is pushed when the isolation switch is used, operation is the same, and the on time of the isolation switch during switching-on and the off time of the isolation switch during switching-off are improved.
