This is my preferred lighted switch: Astrolux SC/SS/S2/S3 BLF X5/X6 Flashlight 2LED Lighting Switch For DIY.
I like that it has a double spring, but cannot guarantee that it’ll work with your flashlight. For that, you’ll have to refer to the following BLF post: D.I.Y. Illuminated tailcap.
You may have to add a bleeder resistor to the driver in order for the functions to work. But once you figure it out, it’s worth the effort.
