Claim:
1. An optical switch device comprising: an enclosure with a first hole on a wall thereof; a substrate; a first assembly for a common port, the first assembly including a first collimator securely positioned through the first hole; a second assembly for a first port, the second assembly being bonded to the substrate and including a second collimator, a third assembly for a second port, the third assembly being bonded to the substrate and including a third collimator, wherein the first collimator is optically aligned with the second collimator through a second hole formed in a raised portion of the substrate, the raised portion is positioned between the first assembly and the second assembly, the third assembly is secured on top of the raised portion, the substrate in secured within the enclosure in such a way that the first, second and third collimators forming a first virtual plane encompassing two respective optical paths between the first collimator and the second collimator we well as the first collimator and the third collimator, and the second hole lies on the first virtual plane, each of the second and third collimators is steadily held up by at least two wedges; and a prism provided to alter an optical path between the common port to either one of the first port and the second port, wherein the prism is on a second virtual plane perpendicular to the first virtual plane, and is caused to move along the second virtual plane, and the third collimator is always closer than the second collimator to the second virtual plane.
