Have you read the geekhack TOS lately? Advanced search bounce or buckle? Please login or register. Did you miss your activation email? Omron switches are the common by far used in mice, however the naming scheme and rumors abound about what each does and is.

Here I’ll try and document as much as I can and dispel some of the mysteries. This took hours to compile, reading websites, pdf’s and more, it contains all you should need to know.

Omron uses two naming methods. The machine ones probably come assembled in trays or strips so the machine can feed them in quickly. This is backed up by the Asus ROG Spatha mouse which uses a machine numbers on the switches inside the mouse, but retail naming on the two switches included this mouse allows the user to change them. This guide covers both, but right or wrong about naming reasons, this is how they will be referred to in order to distinguish them.

The switches by Omron are all designated D2F, from there it gets a bit more complex. We’ll discuss retail switches first, as once you understand them, you can more easily understand the machine switches. D2F vs D2FC indicates origin and more. Tolerances on these are pretty small so you wouldn’t notice, but just know that they are more sloppy than the Japanese models. Japanese models have much nicer internals, better tolerances, better metals,a stronger frame and are better sealed from dirt and moisture.

They are also slightly taller and have a shorter actuation distance, it’s for this reason they are not always interchangeable with Chinese models. No question, the Japanese switch is better made, but unless you use it in a harsh environment, or plan on your mouse lasting 10 years or more it may not be worth the added expense or hassle to install them.

If your mouse has Chinese models, the Japanese models may not fit unless there is a teeny bit of slop between button and switch itself, which is common. Most Logitech can probably handle it, but if not you can always file actuator.

Just remember if you don’t like it and try to go back to the Japanese version things will be very sloppy. Gold is better at fighting corrosion, however it doesn’t conduct as well and needs a bit more power to start conduction. In our situation, it doesn’t matter much and given time and corrosion tarnishthe gold will maintain it’s level of resistance better.

So unless you need the added onron for higher amps, gold is the better choice here as evidenced by the act that better mice almost universally use the Now before you rush out and look for a -F, there are considerations here and it’s really not that simple.


A non -F will have a much more solid click d2fc–f7n it and a faster return. This is important if you play FPS and need to rapid fire. Most people tend to prefer the non -f, especially in gaming mice, but if you don’t game the -f may be your favorite and I can see some of you already drooling, but So if you tend to abuse your mice, the non -f can actually last much longer.

Just another reason for gamers to consider the non -F. As you start pounding the button for rapid fire, you can easily exceed the -F’s force limits which is d2fc–f-7n a little over a pound.

This becomes more relevant in the next section. Remember I said lifespan on the -F was irrelevant, now you learn why. There is a rumor that Japanese switches start with a lower lifespan and that the -F has a longer lifespan.

This doesn’t seem d2fc-c-7n really hold much water when you consider that Omron themselves labels them for you. Keep in mind that these numbers are without any load, and they really do mean ANY load. If the mouse button rests on the switch button or your finger causes it to, then the lifespan will be shortened.

Anything touching that button shortens the lifespan. Your mouse may have some slop to prevent this when your fingers are off the mouse, but as soon as you put them on it, the lifespan is probably starting to drop as the weight of your fingers remove that slop.

Personally, 10M last longer than 20M for me, see my note here.

Omron has multiple ratings: However they often coincided with the button color or a painted dot on top. Some of the lower numbers the details are sketchy, but we don’t really care about them anyhow.

I don’t recommend relying on the d2cc-f-7n color. These are usually older models, but it’s something to keep in mind. Dots and labeling is the only surefire way to know and a while lower numbers may not say it, you can bet a 20M is going to let you know it’s a 20M.

I’ll put a chart at the bottom showing what is using what that I know of and if others post I will try and add them. Frankly, you do not want any of these on your switch, as they pertain to the soldering terminals and different ways to actuate the button, almost none of which are useful to use.

Levers can be removed, so if you want a specific switch in a hurry and omrln only find it with a lever, you can always remove it from the switch and use it without problems, just be careful removing it. A quick Google search turned up nothing. Yes, there are others that can be used. Most agree that the Omrons are the best and by far the most common in quality mice, which begs the question, if they are the norm, why do people and manufacturers make such a big deal d2fc-f-n7 Omrons.

The D2F-F should be more rigid, because that spring needs to be thicker to handle the oomron amp rating. Therefore it behaves less like a spring, and more like a lever.

IF your button has a bit of slop, almost all of them do, however it will probably not last as long since anything resting on the switch will shorten the lifespan.

No idea on the other switches. Recently got some huano switches. Man these things are LOUD. I like the D2F01F better because it’s much less annoying. First of all thank you Leslieann d2fc-f-7j doing so much research. But differently than expected the case has a white button and no clear point in any color. So this mismatches the information you have given. Another points is the “Machine switch Numbers”.

As far as I understood your writing the machine versions are only for component placement systems while the others are for the “retail market” so to say.

Are these the same products differently labeled? Thanks for your help! New Orleans Alps Evangelist. My Logitech M Marathon originally had Himake switches before I swapped them both for Omrons after one switch started double-clicking. The Himakes lasted me many many years though, so I have nothing bad to say about them.

Panp on Sat, 29 October I also added a bit about the switch, omroj assuming that it two has d2fx-f-7n Japanese and Chinese counterpart. Something I’ve personally noticed regarding lifespan, I have found that at least in my case, that 20M switches are not as durable as 10M switches.

While this at first runs counter to Omron, if you remember when I said resting your finger on the button shortens the lifespan, it’s possible that the 20Ms are more easily damaged. So while a 10M may be rated for 10mil clicks, resting your finger on it may shorten it to say 9million clicks, while resting your finger on a 20M may shorten it to 5mil clicks.

In all fairness, this could just be a change in my use pattern, a omorn in Omron’s production or Logitech’s production as the 20s are a recent change for Logitech and their manufacturing has changed so it could be the supplier.

Hard to say, but so far I have not been impressed with 20s. Logitech has the little H shaped plunger bar to reduce over-travel. Whereas many other mouse housings do not.

Omron D2FC-F-7N

So if omrom comparingthat should be taken into account. OR perhaps that switch rating was only possible using logitech’s h-bar. We’re never gonna really know because we can’t test this. Elrick Hype Master Posts: Leslieann on Sat, 29 October Sun, 30 October Thanks for the info Before I went shopping thought it might be a good idea to check the switches in my CM Inferno are compatible.
