The invention provides an electromagnetic switch valve capable of reducing closing time delay. The electromagnetic switch valve comprises a shell, a coil, a static iron core, an armature, a first stator winding, a second stator winding, a first tooth-shaped permanent magnet, a second tooth-shaped permanent magnet, a wedge-shaped magnetizer, a wedge-shaped non-magnetizer, a rotating frame, a rotating seat ring, a fixed seat ring, a reset spring, an auxiliary spring, a valve sleeve and a valve seat. By means of the structure, magnetic field energy stored when the electromagnetic coil is powered on is fully utilized and reasonably converted, the hindering effect on magnetic flux changes of an original magnetic field is reduced, the previously stored magnetic field capacity is released through a special structure during power failure, magnetic resistance in a magnetic circuit is increased, the magnetic resistance can overcome spring force of a reset spring more quickly, and the magnetic field energy is more stabl
