It will unscrew from the inside of the tail cap. Just the same way as you install a mcclicky on a solar force or old 6p. Look past the spring and you can see three holes in a triple formation. You stick something like a ring pliers in the holes and unthread the entire switch from the tail cap. Then you can switch boots,install a fet tie or mccliky, or whatever else you want to do. Don't use a punch! Just search on how to install a Mc clicky switch. I am sure there is a tutorial or something on YouTube. I can try to take a picture tomorrow when I get off my shift.

The lighter grey part of the actual tail cap is the threads. Its pretty straightforward once ya take a peak. Just make sure to twist it the right way. And be gentle. Looks to be a lefty loosy righty tighty thread but don't mark my words. My threads are greasy and its hard for me to see right now.
It actually uses the same threads that the body uses for the tail cap. It is just threaded into the end of the cap. Use tweasers or something small to grip the small three divots and unthread the whole switch from the cap. When you reninstall make sure to not over tighten it, because the three copper wings are what touch the body when you put it all back together. If you over tighten the switch in the tail cap sometimes there can be a gap. If you put it together and it doesn't work, just fiddle with it a bit to get the spacing right. Should only be a matter of quarter turns. There should be a o ring on the boot side of the switch to keep it watertight. I think?
Hope it helps. Keep us posted.
