The invention relates to a 2*2 magneto-optical switch. The 2*2 magneto-optical switch comprises a first collimator, an optical core assembly, a coil and a second collimator which are sequentially arranged from left to right; the first collimator comprises a first optical fiber and a second optical fiber; the second collimator comprises a third optical fiber and a fourth optical fiber; the coil generates magnetic fields in different directions according to the electrifying direction, so that a light beam of the first optical fiber is coupled into the third optical fiber, a light beam of the second optical fiber is coupled into the fourth optical fiber, or the light beam from the first optical fiber is coupled into the fourth optical fiber, and the light beam from the second optical fiber iscoupled into the third optical fiber; the first collimator collimates light from the first optical fiber and the second optical fiber into parallel light beams, or guides the parallel light beams into the first optical fiber
