How to Repair a Worn Out Clicker on an Optical Mouse




After five years in a university computer lab, this mouse wouldn't respond to clicks very well, but after this two minute repair job, it's as sharp as it's first day!

All you need is a bad clicky mouse, like the one pictured, a phillips screwdriver, and a nail file.

Step 1: Remove the Screw

There's only one screw in this model.

Step 2: Take the Top Off

Using gentle pressure and careful motions, start at the back, and wiggle the mouse unti the top comes off. The top is attatched pretty tightly but it's just snapped together, you can pull it open, but be careful not to break it!

Step 3: Remove the Buttons

The buttons are one piece of springy plastic, held in to the top by a couple of springy plastic barbs. Push the barb back with your thumb and pull it past with your other finger.

Step 4: Chck It Out!

Make sure you're careful not to get the scroll wheel loose of it's springs. It's very hard to put back.

If you look at the back of the buttons you'll see some little indentations. These are caused by constantly being crushed into the little actuators inside the mouse by ham fisted, computer illiterate, college "students," whose parents money would have been better spent renting them an apartment in Mexico and sending them daily beer deliveries. These also are the root of the clicky-no-clicky problem.

Step 5: File It Flat and Reassemble

Use the nail file to flatten the surface where the indentations are. Be sure no raised areas exist which might prevent the actuators from being depressed once it is assembled. Reassembly should be easy unless you took the scroll wheel out. Now is also a good time to clean out any bits of people that have accumulated inside the mouse (icky!).

    Thanks for the idea but instead of sharpening mine down, I just put a small piece of masking tape to "fill in the gap". She works fine again!

    Wait a moment. You tell us to file the raised areas down. That means, as I understand, that the actuators will be touched not by the indentations, but by the flat surface behind it. It also means we will get deeper and longer clicks, doesn't it?

    If that is the case I guess your solution works. In my case, my kitty thought it was a real mouse LOL and pawed it a while before throwing it to the floor. The fall is short, but it was enough to remove the whole square thingy out, meaning I now forcefully need to replace it somehow... Be it with blue tack, super glue or pill blister aluminium... Well your article did help a lot, thanks!

    I was so annoyed with my Logitech mini mouse because i had to click a couple of times before it works. This is helpful thank you but instead of using a nail file, I cut a blister pack which is made of aluminum and added one layer of it to the button area where it hits the "clicker", and just used double sided tape. i tried two layers but it wouldn't move anymore haha. I came up with this cz i didn't have any super glue lol. Thanks so much for this!

    I have a Dell / Logitech mouse. My problem is that it scrolls to the bottom of any page I go on. Is there a solution for this?

    If this solution doesn't work for you and if you have some soldering skills? you can switch between the two buttons of the mouse, it means that the right clicker will be soldered in the left and left clicker (which is the defected one) will be soldered in the right (it is less used than the left one).

    I hope this bit helps :)

    You can make your computer switch the left and right click. On my Control Panel there is a section labeled MOUSE where you can choose what the left and right side of the mouse do so you don't have to physically reverse them.

    This switch is also useful if you want to change the hand you use for the mouse or if your having fatigue problems with your clicking finger.

    Hi. Try to remove some of the "scratch-protectors" under your mouse. I found mine under these, but i bet you will need new ones after removing those.

    Thanks for the advice, I will try it tonight so I can use my computer again, but it better work!

    Usually the microswitches get worn out (internally) and you need to replace them. Also, if you file the actuators down *too* much, I would imagine they would no longer be able to push the switch plunger properly.

    Caveat emptor!

    Wow! I have a 12+ year old Logitech MX500 mouse whose LMB became stubborn about a year ago. At first I kept spraying contact cleaner to the microswitch but it didn't really help that much.

    Then I saw this article and this prompted me to look at the back of the LMB. And by golly, it really has worn down!

    Anyway, instead of filing down the back of the button, I got some superglue and put a well aimed dab right smack in the part that was worn out. After the glue dried, it filled in the cavity.

    Thanks for the tip!

    This is excellent advice, which I have just put to good use (two layers of superglue) on a very cheap Advent mouse (sold by Currys in the UK) on which the clicker started to misbehave after about 7 months use. I actually bought a similar replacement just before doing the repair, as I did not want to be mouse-less if it didn't work, but I will now revert to using the old mouse and keep the new one as a spare!
