Definitive Omron Switch Guide for Mice
sscm1:
Hi everyone, I've been trying to restore my FinalMouse Ultralight Phantom, and I'm trying to keep it original, unfortunately, there is no info on the side switches and switch that is used for the scroll wheel. Any chance someone can identify them by a picture?
It says C NO NC on it, and that's it.

That's just how it's wired.
c = common
no = normally open (not passing current)
nc = normally closed (passing current)
Looks like a d2f clone.

I just replaced the left and right click switches in my G502 with Omron D2F-F, it's been doing the double click for at least a year, it only lasted a few months before it started doing it. Disappointed with the quality of Logitech products these days, I also have a G915 TKL, where the keys have started breaking off the stems, they're just so thin and flimsy, and since it's a proprietary design, the replacements are expensive and have the exact same problem.
Anyway, I digress...
I just have one question, that others in this thread with more experience might be able to answer. The switches I ordered from Mouser don't have any indication of the lifetime rating, other than the button color (the only labeling is Omron Japan and D2F-F, no dot), which is gray/beige, which would indicate 10M, even though the OP says not to go by the button color.
My question is, are there different versions of the D2F-F with different lifetime rating, or are they all 10M? On Mouser, it seems like the other variations of the D2F-F just have different pins or are the lever type. Although none of them specify the lifetime rating. 10M just sounds low compared to the blue button "50M" of the switches they replaced, even though that is not legit 50M.
I've only used it for a couple hours after replacing the switches, but I actually prefer the feel of the new switches. That could just be because the old switches were worn. They just feel nicer and more satisfying to press.
I hope they'll last longer than the D2FC Logitech puts in the G502. Opening the thing up was annoying, so many screws, and the stickers covering the screws unavoidably get mangled a little.
It was also a good chance to give the whole thing a deep clean, it needed it.
Leslieann:
Button color is the old way of determining lifespan, with no other markings it's probably safe assume 10m.
Don't be bummed about not getting 50m, more than a few of us feel the higher lifespan models while having a longer life under ideal circumstances (mice are not) they are more prone to being damaged and since the threshold for damage is so low many of us have better luck with lower lifespan switches. I wouldn't worry about it.
Also, you shouldn't blame Logitech for a switch failure... Well, not entirely. They don't make the switch, Omron does however all of these mice are now operating outside the limits of the Omron switch so Logitech and others do deserve some blame. Unfortunately these companies (not just Logitech) built up the Omron reputation as a marketing tool and now need an alternative but would you buy a mouse with some random switch? Probably not.
And yes your old switches were worn, hence the feel.
Bummer about the board but congrats on the mouse, a lot cheaper than replacing the whole thing.

Thanks for the answers. But one question remains, are there versions of the D2F-F with a higher lifetime rating?
I'm not too concerned right now, the switches are cheap enough, but down the road if I need to replace them again, and I know higher lifetime D2F-F switches exist (if they indeed do) I would do my best to seek those out so that the next replacement could be an even longer lasting one.
