description The utility model discloses a rapid opening isolation switch. An insulation board is arranged on one face of a wall body and a shell is arranged on the other face of the wall body. when the rapid opening isolation switch is in a closing state, a turntable is rotated to the closing position, a torsional spring is squeezed by a contact knife and a hinge end, elastic potential energy is stored, when the closing is in position, a locking device enables the turntable to be fixed relative to the shell, and the torsional spring can be ensured not to act. In the case of opening operation, a rocking rod is operated to enable the turntable to be disengaged from locking of the locking device to rotate, the torsional spring releases the elastic potential energy, the contact knife obtains an acceleration speed, the rotary speed is quickened, the opening process is quickened, the distance between the contact knife and the contact end is quickly increased, density of free gases is reduced, electric arcs can be quickly extin
