When the switch is connected to 2 volts, the NPN transistor is active and and the PNP is off. When the switch is grounded, the PNP transistor becomes active, passing current through the LED. Blue is input and green is output.

The NPN is for nothing or for a firework?

Not quite a not gate, thought provoking anyway.
