Strange. Do you mean “thicker”? Or was the nubbin of a larger diameter? Mine was fine, just making for a very sensitive switch. I removed the nubbin, installed a 5/32” o-ring and switch has a nice firmness now.
I generally don’t have an issue with the firmness of the FWxx switch (I always use lockout), but this light in particular had a defect. The diameter of the nubbin was fine, it was just too long. It was physically longer than the nubbins in my other FWxx lights and was pre-loading the switch when the tailcap was tightened down.
I didn’t replace the nubbin with an whole o-ring, I cut a short piece out of the cross-section of a sufficiently thick o-ring to produce a new nubbin which fits in the original location. It’s a tiny bit larger diameter than the original but the rubber stretches to accommodate.
It definitely has made the switch more stable when pressing off-axis and has improved the tactility, even over my other FWs with properly fitted nubbins from the factory. It’s not immediately apparent to me why this would be. Perhaps a combination of the more pliant material and the slightly larger diameter?
I was always using lockout because of the switch sensitivity. But now I don’t bother with the 5/32” o-ring. I lock out the light when I put it away. Yep, I got that you cut the o-ring, but didn’t quite get that “long” meant “thick”. This o-ring segment technique is interesting. You can cut a variety of thicknesses to see what works best.
i didn;t think it had a manual memory [no memory] option…
?
one comment - it will do this [start on low], if you happen to hold the button down ‘too long’
it is a feature, to be sure you have a way to start on low
but you have to hold the button down maybe half a second
maybe your button is ‘sticky’ so that it thinks you are doing a slow press for start-on-low?
Manual memory mode on Anduril software is 5 clicks from ON (“5C”). Automatic memory is 5 clicks, but HOLD the last click, from ON (“5H”). See flow chart.
Edit — Oops. Looks like the Anduril version in the FW3As may not have selectable memory mode. Sorry ’bout that.
I have 9 lights with 3 different firmware…. :person_facepalming:
I bought 5 brand new drivers from Lumintop, I used 3 so far… 1 of them has the memory option… so far… the other 2 new drivers are waiting to be used… WTF?
