Silent Mouse - The Second Encounter

23.3.2005 02:15 | Přečteno: 163801× | non-linux

Having used my silenced rodent for nearly 1/2 year at home, I finally decided to get rid of the clicking noise at work too and here's the how-to. Some people wanted me to translate the original article, but I guess it's better to start afresh with a revised and simplified approach.

I'm not going repeat reasons for silencing mice, if you want to do it, you probably know why. If you don't know why, then just assume there are people who hate the clicking sound.

Equipment needed:
        a Genius Netscroll+ mouse - my original object of experimentation
	genius
	or other type, such as my Dell scroll mouse (seems to be a Logitech)
	dell
	(these two have been proven to work)
        cross-point screwdriver
        soldering iron
        tin-lead solder
        rosin or flux
        sharp knife
        2 cm of thin insulated wire (2 pcs) (only if necessary)

1. Disassemble the mouse. Now you can see the three switches that make more than 90 % of the noise (the 10 % are made up by resonance in the plastic body - I tried to fill it with some silencing material, but got no audible difference).
genius-insidedell-inside

Take a look at the switches, they must look more or less like this one: switch
My method is only possible with this type of switch, if you see other type in your mouse you'll probably have to invent something else. This is the case of middle button of Dell mouse (green circle above).

2. Take notes on the position of white switch buttons. This step is probably unnecessary, as this seems to be always marked on the pcb's.

3. Carefully solder out the two outer switches. In my first attempt I silenced also the middle switch, which turned to be a bad solution. The switch became too sensitive and could be triggered by mere scrolling. I use the middle button rarely, so I left it noisy in the end; but if you do use the middle button often and therefore wish to hush it too, try it, you have been warned.

4. Open the switch by carefully lifting the legs (perhaps there's better word for it) on its sides.

It's wiser to put the switch upside down beforehand, so that the tiny white plastic button won't fall out. It's not a serious problem if you manage to break the legs - just glue the parts together afterwards - or forget it completely and take the risk of mouse malfunction in extreme conditions (e.g. earthquake).

5. Turn the switch cover by 180 degrees and join it with base again.
before: before after: after
What is the purpose? This way the point where the button touches the spring is shifted and somehow the spring now moves gradually rather than at once. The switch lids of the Dell mouse were a bit different, there wasn't enough room to fit the switch after rotation, so I had to make more space with hot solder gun.

6. Solder the switches back to the PCB. They have to be in the same position as in point 2 - if the button was in front, it has to be in front again...

7. In case where only two pins are connected to the circuit (Genius), the pins of the switches are now reversed. To fix it, just connect the outer pins with a piece of wire. (note that this is an old photo, the middle button is no longer silenced and there's no wire there now)
propojky-genius
With other type of mouse double check the schematics on how the pins are used.
The Dell mouse has both outer pins grounded, so there's nothing left to do.

8. Reassemble the mouse and enjoy.

You can check recorded sound of clicking before and after. FYI, the sounds are of the Genius mouse, but trust me, the other one is dead silent too, I was just too lazy to record it.

Side notes: The disadvantage is, that the actual clicking is perhaps not as distiguishable or maybe accurate (no audio feedback in fact), but it's just a matter of getting used to. Other ways I have tried consisted of shortening the distance the spring has to travel, but the noise reduction gained was not satisfactory for me.. Also the mouse buttons are now more sensitive, so you'll get a few false clicks in the first couple of days, before you learn how to handle it.

It works well, my switches look exactly like those in the photo. However, they won't go into each other after I reversed it so I cut off one end of the top part

Yes, not all switches are exactly identical. I met a switch like this one once and I think there was some structure in the lid that just took space and I was able to remove it with a knife.

Sorry to necropost, but... I don't have golden hands, and am pretty sure I'd make a mess of it if I tried to silence a mouse like this myself. I don't suppose you'd be willing to do it for me? I really need a silent mouse, and commercially the only option is the newish Thanko model which I'd have to order from the States. So it'd be worth my while to pay you to hack one for me. I'm based in Prague, btw. If you'd be interested, can you mail me at pDOTfarrington-douglasATseznamDOTcz?

I'm sorry if commenting on old threads is considered "bad", I just wanted to say that I tried this with an optical mouse and it totally worked! :) Thanks for the share! Like one of the commenters, the two parts didn't fit perfectly for me, so I had to cut a little bit of the plastic around the small white moving "clicker". Moreover when reversing was complete, the "big" mouse button didn't hit the "small" white part inside, so I had to add an additional metal "prolongener" on top of the whole mechanism to actually link the new position of the small white clicker with the old one that was getting hit when I click the mouse. I did this by cutting a small part out of a pen spring and straightening it, and then sticking it with tape on the outside of the whole click mechanism. And now it's ninja-silent! That was a very nice thing to do, but it did need patience and some tools(pincers and a screw driver, as well as a needle to disassemble the click mechanism - I didn't want to take it out of the pins, because I was afraid not to damage them and render the whole mouse unusable, a small "swiss" knife is also very useful).

Hey, sorry for bringing it up in 2018 :D but method totally works. I can share experience with my mouse - HP x3500 (G57). I did it another way, I pinched up the black plastic covers of buttons carefully with scalpel without soldering it out. They came off with some resistance. Then I turned them 180 degrees like in tutorial. One of them was broken so I glued it together :D Then I checked if buttons works with original plastic cover of mouse and only left one did. with right one I had to make some sort of extension from guitar pick (~1mm) so it can reach the white small button. Eventually I got it working. Thanks for great tut! Handful after all these years after posting! Cheers!
