If I understand your drawing, then nothing would happen. The LED won't

Led
I. I
Positive-------I I---------switch-------------negitive

In this drawing the LED will light up when the switch is closed. If there
isn't something somewhere to limit the current through the LED, it will
promptly burn up. You need a resistor in series with it to limit the
current
to ~15mA.

When do you want the LED to light up? Anytime current flows through the
switch? Anytime there is voltage applied to the circuit?
