Heya! I've recently thrown together my own corne with kailh choc fittings. When shaking one of my unlubed choc brown switches I noticed a distinct rattle coming from this little metal "clamp" (the thing that's protruding from the stem) wiggling around in the switch. I could probably just lube it for it to go away but what I'm wondering is what exactly that thing is for. From what I can see it doesn't really serve a purpose, does it? So can I just leave it out and be done with it..?
