I've been reading these forums for about a week and still have some questions.

I want to use the style of these low-profile, brass/stainless buttons but am not sure if they will fit or if they are even usable.

(If I can use them I'll only need one so if anyone wants one, we can split the cost)

These buttons have LEDs on them

How would I wire my setup if I add another small LED to light up a slit in the hilt, and/or to power an LED button (sorry, I'm not very fluent with circuits)

Also, I'm interested in using Erv's crystal focus. You don't need a resistor right? Do you need a separate LED for the low battery indicator?[/url]
