Light switch and light switch array

An optical switch comprising:

• an optical fiber array formed by arranging one input optical fiber, a first output optical fiber and a second output optical fiber;
• a rotatable movable mirror for switching over optical paths between the input optical fiber and the output optical fibers;
• and
• a collimator lens array having three collimator lenses respectively associated with the input optical fiber and the two output optical fibers, the collimator lens array being disposed between the optical fiber array and the movable mirror,
• wherein
• the input optical fiber and the output optical fibers are aligned and arranged on substantially the same plane in order of the input optical fiber, the first output optical fiber and the second output optical fiber,
• the movable mirror has a first position for forming an optical path between the input optical fiber and the first output optical fiber, and a second position for forming an optical path between the input optical fiber and the second output optical fiber,
• the first position and the second position are formed by applying drive force to the movable mirror,
• when drive force is not applied to the movable mirror, an optical path is formed between the optical path formed in the first position and the optical path formed in the second position,
• the movable mirror is connected to a stationary member via elastic members formed integrally with the movable mirror,
• the first position is assumed by the movable mirror in contact with a substrate disposed so as to be opposed to the movable mirror, at a plurality of contact portions, and
• the second position is assumed by the movable mirror in contact with the substrate at a plurality of contact portions differing in at least a part from the contact portions forming the first position.
