So I have this 12V 20A SPST toggle switch that has a built in LED. Now when I first bought this thing I was under the assumption that the LED only turns on when the switch is in it's 'ON' position, but after looking at the datasheet some more I realized that it's always on, regardless of switch position. I wanted to do a little circuitry to achieve this effect.
The photo named 'before' is obviously how the circuit is before I did anything and the photo named 'after' is my idea.
The only thing worth mentioning is that I left out component values as I will just pick these based off load requirements, I left out the current limiting resistor on the base of the BJT (forgot), and I don't know if I should use a BJT or a FET.
