I just took the switch boot out of my original edition X-1 and crammed it back in without removing any metal. You can remove the old boot by sliding a tiny flat screwdriver in between the boot and the stainless ring and moving the rubber towards the center. There is a metal post which is about 3/8ths of an inch in diameter, so there isn't a lot of wiggle room, but there is just enough. The trick to replacing it is to use a combination of dishwashing liquid and WD-40 to make it slick enough for the ridge to slide back under the metal rim. I used a pencil with an eraser to push the boot in. Use the eraser end to generally push the boot, and the lead end (not too sharp or you can poke a hole in the boot) to push the edges in. I hope you can find a new boot.
