1) Provide Power to the circuit by pressing on the Power button .

2) Press the switch 1 for input A and switch 2 for input B .

The switch in ON state is and the switch in OFF state is .

3) The LED does not glow if one of the switches is OFF and one of the switches is ON and the LED glows if both the switches are ON or if both the switches are OFF.

The LED in OFF state is and the LED in ON state is .
