Here is disclosed an optical path switching apparatus comprising an input fiber collimator and a plurality of output fiber collimators. Each of the fiber input and output fiber collimators serves to allow a light beam to pass therethrough. The apparatus further comprises a plurality of light beam switching elements respectively disposed between the input fiber collimator and the output fiber collimators to selectively switch the light beam from the input fiber collimator to the output fiber collimators, each of the light beam switching elements including a support member having a rotation axis, a peripheral surface, and an extension plane extending from the peripheral surface in parallel relationship with the rotation axis, and a first reflection member securely mounted on the peripheral portion of the support plate within the extension plane of the support member, and a second reflection member securely mounted on the peripheral portion of the support plate within the extension plane of the support member, the first reflection member having a first reflection mirror surface to reflect the light beam from the input fiber collimator, the second reflection member having a second reflection mirror surface to reflect to the output fiber collimator the light beam reflected by the first reflection mirror surface, and a drive actuator for respectively driving the support members to allow the support members each to assume two different rotation positions including a first rotation position in which the light beam from the input fiber collimator is reflected by the first and second mirror surfaces, and a second rotation position in which the light beam from the input fiber collimator passes between the first and second reflection members without being reflected by the first and second mirror surfaces.
