I'm working on the wiring schematic for my first build and I'm trying to figure out how to wire a charging indicator.

Electronics:
7.4V battery pack (2x 14650 Li-Ion)
1000mA buckpuck (4 wire)
Green Cree Star LED module+heatsink
Green latching AV switch (power indicator)
Green accent LED (charging indicator)
Switchcraft recharge port
2x 220Ω ? 1/4W resistors

I want the AV switch to light when the kill key is removed and the blade LED to ignite with the latching switch pressed which is represented in my diagram. I only want the accent LED to be on when the saber is charging, but off when a plastic kill key is inserted or when the saber is in use. My diagram shows an "always on" setup for the accent LED which is not what I want. How do I wire the accent light to only be on when a metal charging jack is inserted in the port, charging or otherwise?
