Proposed in this paper is the design and fabrication for novel polarization-maintaining (PM）optomagnetic switches.Herein two scheme are presented which are 1×2 devices respectively.Theoretical analysis shows its working principle and optical performance.Experiment validations demonstrate their effectiveness in addition.Results obtained show that the switch devices can be more compact and easily assembled by adopting proposed scheme,and the optical performance of the design is excellent which featured by their ultra-low channel crosstalk,super polarization extinction ratio (PER）and insertion loss (IL）as well.
