Picture of Ninja Mouse: The Silent Click
Instead of trashing that obnoxiously loud mouse to get a new one, save some money and the environment by modding it into a Ninja Mouse. All you need in a thin knife and whichever type of screwdriver to open it.

NOTE: This mod only takes a few minutes.

Step 1: First, Some Numbers

Picture of First, Some Numbers
Using an Android decibel meter, I got the following data:

-Ambient Noise 48 dB
-Ninja Mouse 52 dB
-Regular Mouse 74 dB
(The regular mouse is just as loud as my Ninja Mouse used to be.)

If you know about logarithmic scales, you can see Ninja mouse is over 10 times quieter than the regular mouse!

Step 2: Open It Up

Picture of Open It Up
There are a lot of different types of mice out there and most all employ means of hiding their screws. Check under the plastic pads and in the battery compartments if you're having trouble finding them.

When you get inside, locate the mouse switches. You should see some rectangular boxes like in picture 3. If you have the square switches like in picture 4, you're out of luck. There isn't a way to quiet them down that I found. (They use a thin, metal concave disk than flips to being convex when pressed. Putting anything in there to quiet it down makes it lose all functionality.)

Step 3: Open Up the Switches

Picture of Open Up the Switches
Open up the switch by inserting the tip of your knife into the clip of the switch cover and gently twisting the knife until it unlatches. Unlatch the other side, it should be easier.

Do this in an area where with dark flooring. That little white button likes to get away and it's really hard to find on a white floor.

Step 4: Press Down the Tab

Picture of Press Down the Tab
Using your knife again, push the tab down to shorten the gap between the contacts. Test the switch and its loudness by pressing down on the cross member where the white button would normally press.

If you bend the tab down too far, just bend it back with the knife. The metal is quite malleable.

OMG, this is a life saver. I was seriously going to shell out some cash for some pain relief from repetitive clicking. Thank you so much for putting together these instructions!!

To those that broke their mice, sorry that happened to you. That's the inherent risk of any DIY but you shouldn't blame the poster...

i tried to make this... it made my right click super overreceptive, and completly broke my left click... i have been trying to fix it for the last two hours. i may need to get new switches... or something. i don't reccomend trying it.

Is there another way? My mouse screw is in triangle shape...i don't have the screwdriver either, so i can't screw it.. help!

Managed to render my $40 wireless Logitech mouse almost useless using this method ;(. What happened in my situation is that the metal thing popped out, and when trying to put it back in, the bended park broke off.. It was on the LMB, unfortunately.

excellent tutorial, it was hard to take the black boxes off but i did it, also i was lucky the little button was not white but purple, and i did what aleunge said, putting a small piece of duct tape over it and it worked excellent, very easy tutorial, i had never made something like this, thank so very much

My God thank you so much for this Instructable. I have 2 dogs; one with super sensitive ears and the other dog is really old and needs his rest and to not be aggrivated constantly by that noise. When they are sleeping they keep waking up to moan and groan and make it obvious it's driving them crazy. I usually get off the computer before I'm actually ready to. They've got me trained pretty good. LOL. :) THANK YOU!!!

You're welcome! Give those dogs a belly rub from me.

Good hack. But to make it almost completely silent (similar to my MS Arc Mouse) while keeping much of the button travel:

- put a small piece of duct tape in between the little arched piece the OP is recommending we bend down and the thin metal sheet that does the actual clicking (the top arched piece is basically a small magnet that attracts/pulls the sheet back up after you click it/pushing it down, essentially the spring mechanism of the button). By placing a small piece of duct tape there, you're cushioning the button return, which is actually the loudest part. Don't double the tape up or use something else thicker though as it will insulate the magnet too much from pulling the sheet back up with enough force.

- the tape will also reduce the travel of the button a little, but if you bend it like the OP is recommending as well, the clicking sound would reduce even further (but don't bend so much as the tape already reduced the clearance).

After that, enjoy a real silent mouse but still have the clicky feel of the original button.

Absolutely wonderful guide. My switches were mounted on a board that made it impossible to get the sides off but luckily the board came out no problem. Thanks :)

Well I just killed my mouse! Broke off the little flat spring. Looks like one end was soldered on, but no more. I got the right-click side done and it looked like it was going to work well until I broke the spring off the left-click side. I guess I get to go buy a silent click mouse now.

I thought I did the same thing first time I tried. You can actually pry it back on, it's just held in place with tension. It took a surprising amount of force though.
I will get a strong light and magnifying glass and see what I can do.

I just made it on my G700s, it works nice!
Pros: The noise got greatly reduced, now i can work ( and play :p )at nigth without waking up my parents or my brother

Cons: Was a bit difficult, that metal plate is tricky to put back into position. Other problem is the mouse skates, they are difficult to put back on perfectly. One last issue is that it changes the feeling of the button a lot, it becomes mushy, so it takes time to get used to it.

slimyd8 months ago

I cannt open the mouse switches. HELP

use a cutter blade. a magnifying glass migth come handy too, just slide it in the space between and gently twist the blade until it clicks off. repeat on the other side and be extra careful with the small white button and the metal part, they are ver very small

Awesome tip, took about 15 minutes and clicking is a lot better now. I don't understand why only a handfull of mouses are silent, most of them are so unnecesery loud, like my Apple mouse, at night when everybody is asleep I have to use my touchpad instead of the mouse.

Did this with a Steel Series KinZu V2 Mouse - worked like a charm. If that white button does fall out -you WILL need tweezers to get it back in.

Thanks for the detailed manual. However, I want to warn people about
that at least my mouse after this procedure became tougher (buttons are a
bit harder to click). On the other hand, 1) it became easier to click
frequently, which allows to shoot more bullets per second, and 2) when
you get used to hard buttons, you start to hold a button a little bit
stronger and in the end you need less time after a decision to click to
actually do it, which is good for sniper rifles.

We have the same mouse, cool.

is it just me or is the sound gettting louder?

gkim91 year ago

HOLY CRAP. THANK YOU SO MUCH. SO QUIET. I can now safely play game without my mom noticing.. If you reply, it will be an honor. thank you very much.

sshuggi (author)  gkim91 year ago
The honor is all mine. I'm actually surprised this has over 125,000 views! I haven't looked in a while.

Nice one dude! Saved me from buying a new mouse. My old one is now as quiet as a... mouse.

BTW, for anybody about to try this mod, remember that there is a trade-off between quietness and tactile feedback. The lower you go with the contact the quieter it will be but there will also be less travel in the button and that can be slightly disconcerting when you're using the mouse.
sshuggi (author)  meektweak2 years ago
Yea, my friends that use my computer are always saying, "What's wrong with your mouse? It clicks weird." It took me a few days to get used to it. Nothing really.
gkim9 sshuggi1 year ago

got used to it in 5 minutes.. :D:D:D:D

nycnelson1 year ago

Thanks for this. In case anyone is wondering, the click sound is produced when the horizontal metal swing magnetically snaps between the overhanging arm and the connector that registers clicks beneath it.

On my mouse, the overhanging arm/tab is designed differently. It's thin and rectangular, but positioned vertically making it difficult, if not impossible, to bend without inflicting damage. Instead of bending the arm, I shimmed the swing instead. Cut a small square of electrical tape and use some tweezers to set the tape between the tab and the metal swing. Shimming is completely reversible. Add or subtract more layers to your own liking. If you don't have electrical tape, you can use Scotch tape or even squares cut from Post-It notes (from the part that has the adhesive on it).

This instructable is great! I turned my freakishly loud mouse into a near-silent ninja in about 5 minutes. I got to the part before you open up the switches myself, but this showed me how to open them up and silence them. Thanks!

How about the mouse wheel switch. Same way?
sshuggi (author)  noparallel2 years ago
If it's the same design, yes. Mine uses the disc type button for the middle mouse button (wheel click) and it can't be silenced. If you're talking about the wheel roll itself, there's an instructible to silence that which someone mentioned below. Here's the link.
ArtixAvian2 years ago
Hmmm is there anything at all possible if you have the other type of switch in the mouse? I've put a tiny bit of tissue in which helps but really its still quite an annoying click lol.
sshuggi (author)  ArtixAvian2 years ago
Nahh, sorry. I haven't had to deal with the disk ones. The only thing I can think of is putting it on a flat metal surface and trying to flatten it slightly with a hammer, but not so much that it won't reach the contactors when pressed. The issue with that is if you mess up, it would be really hard to hammer it back into shape to actually work. Perhaps a ball-peen hammer could shape it back? Either way, I'd try it out on an older mouse.

Quite a good Instructable ! I was pretty surprised that a low-cost mouse has the same click system than a $70-Razer.

One day I tried an even more drastic way to silent the mouse: replacing all the click system with a metal flexible strip and a little electric cable so that there is absolutely no "click". If I can do it again, maybe I'll do an Instructable with it.
sshuggi (author)  yatto2 years ago
I look forward to seeing it. Post a link if you do.

Simply brilliant! Like others, I came across this while unsuccessfully shopping for a quiet mouse as our PC is in the bedroom. This worked beautifully! I actually have the same HP mouse as you have pictured, though mine only registered 49 db. This took it down nearly a full 10 db; plus, I like the reduced click effort. This mouse has worked very accurately for my Photoshop work, so that makes it a real bonus to not have to waste money replacing it. Thank you so very much!

Well, I noticed my microphone was picking up mouse clicks while recording game footage, so I decided to give this a try since I had a spare mouse. It was a bit of a disaster, having broken the clip of one of the plastic caps (that and the little plastic button was black like the cap, so that was fun), and also snapping the copper cross member while trying to bend the swingarm back into place. The left button one stayed put while the right just fired right out when the cap came off.

Sooo, I ended up popping open a 20 year old ball mouse for a replacement cross member because I refused to give up. Headaches aside and hours upon hours of playing Operation with a pair of tweezers later, I can boast a marginal success. Still, it was a fun experiment and now I can barely even hear my mouse, let alone my mic picking up any noise. Thanks for the guide!
