Abstract
An optical switch (1) in accordance with the present invention includes: a housing (50), an input port (10), a plurality of output ports (11), an optical switching means (20), an indicating device (30) and a driving device (40). The optical switch includes a resistor (37), a fixed reflector (23) and a carrier (21) to which a moveable reflector (25) and a wiper contact (35) are mounted. The wiper contact slides on the surface of the resistor as the carrier moves along a pole (215), changing a resistance provided to a control circuitry. The control circuitry then provides control signals to turn on a light emitting component (31) above the output port which is optically connected with the input port.
