ABSTRACT:
A reduced current consumption circuit for multiple optical switches 10 having associated status indicator LEDs 26. The reduced current consumption is achieved by electrically connecting the emitter IREDs 14 of each optical switch 10 in series with the status indicator LEDs 26 and a constant current source Ccs 12. Each status indicator LED 26 includes a shunting circuit 34 which removes the LED 26 from the series circuit in response to an output signal from the receiver 18 of its associated optical switch 10 without breaking the series circuit.
