Abstract
An optical switch ( ) in accordance with the present invention includes: a housing ( ), an input port ( ), a plurality of output ports ( ), an optical switching means ( ), an indicating device ( ) and a driving device ( ). The optical switch includes a resistor ( ), a fixed reflector ( ) and a carrier ( ) to which a moveable reflector ( ) and a wiper contact ( ) are mounted. The wiper contact slides on the surface of the resistor as the carrier moves along a pole ( ), changing a resistance provided to a control circuitry. The control circuitry then provides control signals to turn on a light emitting component ( ) above the output port which is optically connected with the input port.
