<p>An optical switch that any vibration or oscillation transmitted to the optical switch from the outside is substantially prevented from being transmitted to a movable electrode is provided. In an optical switch comprising: a stationary electrode; a movable electrode opposed to the stationary electrode with a predetermined space therebetween; and a mirror mounted to the movable electrode, wherein the movable electrode and the mirror are moved together by applying a voltage between the stationary electrode and the movable electrode thereby to switch the path of an incident optical signal to the optical switch, a buffer member provided with a diaphragm is attached to the bottom of the stationary electrode, and a vibration or oscillation is substantially prevented from being transmitted to the movable electrode by the damping effects of the diaphragm and the space area formed above the diaphragm. <IMAGE></p> |
