I see the store shows you how to wire this up to the saber's 3.7v power source to get the lights working from turning the saber on, but is there a way to use the momentary switch to turn the saber on, and have the lights come on with it? Seems like once you cut the traces as shown, you can only use the momentary switch to turn it on, but the lights won't work. I've seen plenty of youtube videos where people are doing this, but no tutorials. Thanks!
