Claims

[Scope of utility model registration request]

Optical coupling is achieved between the first and second support members by relatively moving a first support member having at least two optical fibers and a second support member having at least one optical fiber. In an optical switch device capable of switching the combination of optical fiber pairs, the relative movement state of the first and second supporting members is maintained by buckling deformation of an elastic member capable of jump buckling. An optical switch device characterized by:
