PROBLEM TO BE SOLVED: To prevent an axial shift from occurring in a second optical fiber in a V groove and a light connection characteristic between a first optical fiber and the second optical fiber from deteriorating by vertically vibrating an elastic support plate due to external stress, etc. SOLUTION: A fiber introduction mechanism 40 applied to this switch is provided with an optical fiber arranging member 14 parallelly arranging the first optical fibers on a fiber arrangement groove 15, an optical fiber fixing arm 41 introducing the second optical fiber 2 to the fiber arrangement groove 15 of an optical fiber arrangement member 14 and a drive mechanism 42 driving the optical fiber fixing arm 41. In such a case, the optical fiber fixing arm 41 is formed by a rigid member without bending for prescribed load, and a pressing part 47 pressing the second optical fiber 2 to the fiber arrangement groove 15 is provided on the free end 41a of the optical fiber fixing arm 41. |
