I got a PC10 about 2 months ago that had a spongy/squishy & gritty feel t it. After some research on the forums I figured the gritty could be solved but the squishy was inherent with Jetbeam light. I returned it because I am used to the Fenix way and like the feel of there switches.
I've heard people complain about the switch in Jetbeam's P and B series lights, but I own a BC-10, PA-10 and PC-10. The BC-10 was my first ever name brand LED light, and its still my EDC light that spends its days in my front pocket scratching up against my keys and other objects, and it get used at least a little just about every day/night, and I didnt really pay attention to the squishy-ness of its switch when I first got it because I had no other lights to compare it to. Now that I DO have other lights to compare it to.... I dont pay attention to it at all!
Its absolutely not a big deal. Its got a tiny, insignificant little space between the boot and the switch but who cares? It doesnt have any negative consequences at all. Also, its boot isnt really thin like someone else said,
and Jetbeam includes an extra boot with these lights anyway.
As far as the switch itself, it is a long throw switch with more travel to it. Its not as heavy feeling as other switches, but that doesnt mean its weak. It just doesnt seem to have as stiff a spring built into it. It doesnt seem to be as smooth in its travel as other switches, as there is some minor roughness, but its extremely minor and its always been there but hasnt either gotten worse or caused any problems at all.
I dont have any tools to remove the switch as nothing I've tried like scissors or tweezers has worked, so I havent been able to lubricate the switch at all. But it still works as consistently as it did a year ago.
All in all, I think people are being way too picky and concerned over this.
