How does this momentary tactile switch mount?

I was checking this little guy out:

I am not sure how it mounts in the hilt though. Do I need a plastic switch ring to hold it in place?

Silver Tactile switch
-To snugly mount, use a 13/64" bit.

It just presses into place. Be careful not to twist the switch while you're inserting it, or you may damage the switch frame. Once pressed in place, it's unlikely to come back out.
