Abstract :
The structural design of the switch element is evaluated theoretically and experimentally, and an optimum combination of membrane length and insulator thickness is obtained. Based on the results, a 32-element electrostatically driven switch array is fabricated; its switching performance was found to be excellent. The switch array is applied to a subscriber transmission system using an abnormal subscriber end. A disturbance light from an abnormal subscriber end is successfully interrupted
