Repair and Upgrade Dodgy Mouse




Introduction: Repair and Upgrade Dodgy Mouse

I am a moderate gamer and the main problem for me is mouse left click starts to double click for after every 1 to 2 years of usage. I found some hacks to correct this but eventually problem comes again.

So couple of years back I bought razer deathadder mouse thinking it will lasts forever for its price. But I was terribly wrong, even those expensive mouse will fail eventually. So I cannot throw this mouse away and buy a new one as I did earlier with my cheap mice.

I also wrote a small java program to test the mouse double click problem. you can identifiy how bad is the switch by comparing total clicks and double clicks in the application.

I am including rar file of the exe file and rar file of code also if you are curious

Step 1: Parts Needed

Soldering iron

Desoldering pump

Micro switches

and a dodgy mouse

Step 2: Replacing Switches

Most of the expensive mouse have Japanese made omron branded switches. I found a pack of 5 omron micro switches for just 5$ including shipping in ebay. Link

They are some different models in omron switches but most popular are D2FC-F-7N 20M, where 20M represents 20million clicks lifetime of the switch.

I simply I opened my deathadder, removed every screw I can find to free main board from the mouse then desoldered old swathes and added new ones, now my mouse is back to its glory.

But the interesting part is upgrading cheap mouse with these good quality switches.

Step 3: Upgrading Cheap Mouse

The major difference between cheap and expensive mouse besides flashy LED lights and ergonomics is its sensor and switches.

Sensors in expensive mouse can have varying sensitivity, this can be controlled from the software they provided, which can sometimes be dodgy and consumes more system resources. Sensitivity in my deathadder can go up to 6400 but I never used it above 1000. So I think plug and play mouse is way better than using custom software.

So the major difference for me is switches, cheap mouse have these terrible switches with terrible life.

So I thought cheap mouse with better switches could be better than using expensive mouse.

I have a 10$ logitech mouse lying around with a double clicking left clicker. I replaced both clickers with these good switches.
Now mouse works and feels great, adding 2$ worth switches to the 10$ mouse makes it feels like an expensive mouse. This is a simple and cheap hack which can make your mouse feel like an expensive mouse.

    Although I am unsure whether I could do this myself (unless it came in a kit) I am glad there is an alternative to having to buy another mouse that may be cordless. The old wired mice are getting harder to find, unless you don't mind an el-cheapo, and it's annoying cheap features. I must have a corded mouse, because otherwise I would never find it! I admit I have a very messy desk, and things fall off all the time- including the mouse. It's easier to find a wired mouse than to search under my also-messy desk for a wireless. Thank you! Hope you can make up some repair kits in the future to sell to clods like me! XD

    Look for a gamer mouse, most of them has got a tail - or go low tech and put a string in a wireless mouse.

    same with me :) with latency, maintenance and all, wireless mouse is not my thing. If you are new to soldering first try on any broken electronics, this can be good practice for soldering,


    Part of the problem is that the buttons have too short a travel, so sometimes a temporary fix (when you just need it working ASAP), is to cut a few bits of tape and layer under the plastic button.

    Mice are made for moderate use only it seems. Back in time I got the problem after little over a month on a Logitech Trackman Marble, Left it in for repair under warranty and about a month later, I got a replacement (why did that have to take so long?). This replacement went belly up after an equal amount of time and I had to wait about a month again for a replacement. Guess what happened in another month of use... I gave up on it although it was one of the best pointing devices I ever had ergonomically (and thus non-pain inflicting) speaking.

    It's easy to make a better switch, but the manufacturers wants the average user to replace their mice every now and then, leaving us "heavy users" to be very regular customers... Or find alternative solutions - I have soldered too many switches (from right button switches of dead mice as well as new) to think it's still fun and I'm now attacking the problem from two angles... A pedal for backup and developing a replacement switch that doesn't go bad in a blink, which any brand of regular mouse size microswitches will.

    wow grate idea of putting tape under switch, next time when I do this first I will check for switch travel before soldering permanently :).

    I never thought of a permanent solution to this problem until I bought an expensive mouse. there are many of my friends continues to use those dodgy mice just because they cannot throw away the expensive mouse and not aware about this solution.

    I don't put the tape on/under the switch, but under the plastic piece that pushes on the switch (the piece that your finger touches).

    It is a very temporary solution, won't hold up for more than a week or so, but it may just get you through an important project with your sanity intact :) and give you time to get a replacement switch.

    I did the same thing to fix my gear head wireless mouse that had bad left click. It would not hold, making it difficult to drag, and the clicking was quiet compared to other mice. So I removed a switch from a broken crap labtec mouse (these mice have terrible cables) and replaced the switch in my gear head mouse with the switch from the labtec mouse. Now it works well again!

    grate, I am using deathadder and switches in it felt grate, so I looked what they are using in that and ordered those for my cheap mouse, boom! now my cheap mouse feels like expensive one ;)

    You don't even need to buy new switches; just look for some cheap mouse that hasn't been used much and has good switches (like a labtec mouse that had its usb cable break).

    My mouse had a broken scroll wheel axis. I replaced the axis with a short steel wire and glued that with epoxy. Pretty sure the mouse will fall apart before this fix will break again xD I'll remember the click replacement once it's getting time for it!

    That's the mouse that I have. It's a great mouse!

    Awesome! I've got a double clicking mouse sitting here, I wondered what was wrong with it
