CFX and 16mm AV ring switch wiring.

[Vehemet]

Hey all, finally attempting to build the saber I bought at the start of covid.
I've attached a wiring diagram, and I'm following Nick Kurszewski's excellent playlist on his build. I made a few changes from his though and am fairly confused regarding the wiring/resistance needed.
Mostly I can't find what each pin on the 16mm Anti Vandal Latching Red Ring Switch is so I'm not sure exactly how to wire it. I'm also fairly confused as to how much resistance I need to include with this one.
Per the shop page, "The LED has a forward voltage of 2.1V and runs at 20mA. 4.8V would use a 150ohm 1/4 watt resistor, 6V would use a 220ohm 1/4 watt resistor."
I don't think I'm missing resistance anywhere else, and the Aux switch isn't specific on polarity if I'm correct.

Thanks all.
