Pack of 4 OMRON D2F-01F Microswitch SPDT Subminiature Compatible Mouse Switch

Sdered these onto my wireless Logitech mouse when the switches started to go out. Works perfectly now. Can't tell a difference from what was in it before.

Bought a set of these to fix the infamous double-clicking switch problem with some of Logitech's recent mice, my particular one being the G903 wireless mouse. The problem, as has been mentioned by many others, is that the mouse ships with cheap Omrons manufactured in China. They're prone to failure, and my G903 started developing double-clicking problems within just a few months as a result of that design choice. Cleaning the switches seems to help a little bit, but after nearly two years it's a near-ubiquitous concern that is very hard to live with because of how much it interrupts gaming and work as well as basic computer use.I did some research and decided that I was better off fixing the problem myself. RMAing the mouse would just get me another model with ticking time-bomb switches, so I whipped out a soldering iron, tweezers, and a screwdriver and got to work. The mouse is easy enough to take apart, but there are a lot of very tiny screws to worry about. The hardest part of the process for me was desoldering the old switches because I'm out of practice and honestly not that good to begin with, but once I figured out the best way to do it, these significantly higher quality Japanese-made switches dropped right in and work just fine after reassembly.The click feels quite a bit more robust, in my opinion, and I think the switch module is taller or maybe requires less force to press, because it seems like it actuates much faster than the old ones, but that could be due to its snappy feeling. Overall a great buy, especially since I have backups in case something else happens that merits another full repair.

Excellent replacement switches for my Logitech M570 track ball assembly. Must have board level component removal and replacement skills to install.

I have Logitech Performance MX mouse http://www.amazon.com/Logitech-Wireless-Performance-Mouse-Mac/dp/B002HWRJBM/ref=sr_1_1?ie=UTF8&qid=1422251355&sr=8-1&keywords=logitech+performance+mouse+mx that I bought from Best Buy for $99.99 back in 2012. I love the ergonomics of this mouse but I hate the left and right click micro switches that this mouse comes with. Those are Omron D2FC-F-7N Made is China. Left click started double clicking after a few months of usage and most of these mice are shipped with this specific cheap Chinese made Omron. Well, I love logitech for their customer service and this mouse because it can perform on almost any surface (dark field technology is what logitech calls it). I called logitech and the RMA process was super fast and super smooth. They sent me a new mouse, but same thing happened after a few months. I opened the mouse, fiddled with the switches and somehow fixed 'em and the mouse performed very well for a few more months.Now, in 2015, left micro switch again started double clicking and I opened the mouse body again to try to fix the thing. But this time, I broke the left switch. I was like "dang it - I gotta buy a new mouse". Then I started thinking rationally and would think like "what are my other options"? First, I was looking at simple solution to buy Logitech G700S. But again, I loved my mouse. Then, I wrote down the micro switch number and tried here at amazon. I found it http://www.amazon.com/s/ref=nb_sb_ss_c_0_9?url=search-alias%3Delectronics&field-keywords=d2fc-f-7n&sprefix=d2fc-f-7n%2Celectronics%2C149&rh=n%3A172282%2Ck%3Ad2fc-f-7n . But then those were same Chinese made cheapo switches. I knew they would give me same headache. Then I found Omron micro switches D2F-01F which are Made in Japan for two more dollars I would still get 4 switches. "Hmmm!" I said to myself, I didn't have no soldering experience and no solder iron either. Well, here is what I did. I ordered these Omron Japanese switches, along with Hakko DASH Soldering Iron, 25W which was a super pleasant surprise for me because that solder iron is also made is Japan and is a very good quality. I also ordered Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces), which turned out to be a good quality as well, and I ordered Blue Sucking Vacuum Desoldering Pump Solder Sucker Remover Tool.It took me almost forty minutes for the complete process of opening the mouse body and taking out the mouse board to desolder the left and right click switches and solder the new ones to put back everything together. (Mouse feet were totally done for since I had opened the mouse for several times. More one that later). When I put the battery back and turned on the mouse, I was like "O-M-G". It was totally like a new mouse under my hand. And the click sound and the way the micro switch pushes back the click button is totally different than the original micro switches. I was and I am totally happy with these Omron Japanese model micro switches. Five Star performance out of five stars! And, on top of that, I have made two soldering and desoldering tools along with two back up switches.Next problem was that all the three mouse feet were done for. I again sat for a while and thought about it. Here is what I did. I cut and stick five folds of a duck tape for each mouse foot and then used a sharp pair of scissors to give a good shape. Then I used two tiny droplets of Loctite Super Glue to stick those tape feet to the mouse body (Caution: Please do not drop super glue on the screw heads or screw holes while putting duck tape or electric tape or whatever you choose to use the baseline for the mouse feet.) After that, I cut three hard plastic packing material pieces to use as the actual smooth feet for mouse. I filed them too on all the sides and then stuck them on the duck tape feet with the same super glue and my mouse has super smooth feet as well. As a side note, I must tell you that I have personally tried several times and with several different mice the same duck tape and plastic feet experiment and whenever you want to rip open the feet to get to the mouse screws, the duck tape will be so easy to remove even when you have stuck it with super glue.I highly recommend these Omron japanese micro switches over the Chinese made switches. Thanks Amazon :)

Installed the new switches and have a 1% double click rate in the initial testing swap. both switches**********************UPDATEtried over non-bluetooth and the double clicking is gone...

Legit. Work great. I really like the tactile click and weight of these switches. Not quite as spamable as a softer switch. Do yourself a favor and pickup a solder sucker to de-solder the pins/legs when switching these out.

I have a Logitech G500 mouse that's been registering double instead of single clicks. I couldn't even click and highlight text without it "letting go" of the highlighted area. It's been driving me nuts. Otherwise, I like the feel and specs of the mouse, but this problem is well documented in various posts and on YouTube. This fix works. There are videos on YouTube that detail how to take the mouse apart. Don't try to just take it apart without viewing the videos because the parts are easily damaged. There's only one way to disassemble the mouse so that you can lift out the board to desolder the old switches. Be sure to mount the new switches down tightly to the board. To remove the old switches I crushed them first with pliers because it's nearly impossible to completely remove all the solder from the 3 posts so that the switch can be easily removed. Once I crushed the old switches I used small side-cutters to cut the remaining piece into 3 separate pieces that would just fall out individually when heated. You can use a soldering wick to remove any solder that may have smeared on the board or is blocking the mounting holes. The procedure went really fast when I used this method to remove the old switches. There's a 3 part video on Youtube that shows how to disassemble the G500 mouse that will help you get to the switches. The video doesn't cover how to remove the switches or solder in the new ones. I just know how to do that. Good luck.The Youtube video is titled: HD Logitech G500 Usb Cord fix/ Disassembly part 1
