TX Switch pullers CNC version is a premium option to assist in pulling out switches from plates. The design of the puller helps to widen the bottom end of the puller which allows for additional support whilst removing switches and providing support throughout the process.
I got this switch puller upon a recommendation. I honestly feel it's one of the worst I've ever used. It doesn't do a good job of compressing the switch tabs to loosen the switch, and it can also scratch your plate if you're using a metal one. Overall, absolutely not worth the price, even the generic $5 amazon ones do a better job. Go with the Gateron or Wuque pullers, this isn't it.
