How to repair a worn out clicker on an optical mouse

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!).

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.

This problem is caused less due to ham fisted, computer illiterate etc users and more due to the use of smaller sized mice compared to the user's hand. When a user works with smaller mice, he/she gets used to gripping the mouse with fingers rather than controlling with palm, which causes the harder clicks and the clicker wearing out in shorter time. We also have less choice nowadays with mice being manufactured smaller and smaller.

Thank you for posting this. I watched a Youtube video and lost the url that showed how to make the scroll quiet I took out the spring and had to use your photo to put the black piece on the wheel back to together so thank you for helping me :)

I am an avid gamer and had this problem with the right mouse button on a very expensive mouse. As an alternative to filing i built back up the groove using a hard plastic glue. It takes longer because you have to wait for the glue to set up but I think it's worth it to not have a change in the depth of the button press.

Repairing a mouse with a nail file! Lol! Reminds me of an old joke. "How did you fix the TV?" "Nail file!"
Oh my... if I knew it was this easy I'd have fixed my beloved Logitech TrackMan weeks ago. I was preparing to replace the button itself. Sure enough I looked closer at that little plastic bit and there was a tiny little grove eaten into it where the button made contact.

It was easier to build it up than sand it down, so a tiny piece of duct tape later it's as good as new.

6+ years later and you're still awesome. Thanks. ;D

Thanks, this tip was very helpful. Just repaired my left click. :)
It is funny because the mouse you used is the same exact model I have, very helpful!
ive got the problem of the left clicker hardly working i know its the case not the actual button inside its deffo the case button but i dont see how this will fix it as the mouse needs them sticky out things to push the button how is making them smaller going to fix it ive got blue tac on mine to make 1 of them sticky out things longer so it hits the button better
I was able to fill in the dimple with super glue. It creates a flat surface and just let it dry before reassembly. So far it is working great. I hesitated actually making the whole surface flat by remove height. Granted that i added height to the whole surface.

Do you know how to put the springs back in?
I'm sure you already found this out, but this page has a few mouse diagrams on it:

And another instructables site here may help:

Thank you so much, that worked perfectly! I was surprised, because the divot/indentation was so small, but filing worked great. There were several small raised portions of the surface, at the corners of the area to be filed, that looked like they were part of the original manufactured part. However, filing those off did not cause a problem with clicking.

 This is brilliant, but I think I found a slightly easier way.  Since the parts you are filing off extend slightly higher than the dented area, I *think* these side parts are are there to prevent someone who is pushing down too hard from damaging the micro switch.  To eliminate the need to file anything, I simply cut a piece of duct tape into a tiny strip that would fit over the tiny indented area.  Of course I let some overlap so the tape does not come off and "form fitted" the tape along the sides of the plastic tabs so that it will stay there.  I just used a toothpick to press the tape down the sides of the tab.

I am thinking the duct tape will have enough cushioning to it that even if someone does press down too hard, the side projections can still help the switch not be ruined.

Of course I may also be wrong in my assumptions - however, the duct tape does work.  I did this to a Logitech Trackball mouse.  

Thanks for making this 'ible!

Do you think you could take a few close up pictures of the "hard to put back" springs. I received a bag of parts for this mouse and a very sweet please and one of the springs has me stumped

The more Modern Dell (aka Logitech) Optical Mices have FOU (4) screws - two under the front sliding pad and two in the battery compartment under the "+" and "-" signs. They also have about a jillion parts, including a couple of springs on the side buttons, so dissamble them over a nice white sheet!

Thanks for the great tip. I tried this on my Logitec trackball and it worked like a charm. i was about ready to buy a new one, you saved me $40.

Thank you for reminding us that often the problem is an easy fix of a less than obvious connection. I threw out my mouse thinking I would not easily find a replacement microswitch.

This is a cool little idea. Thanks! I thought for sure you'd show how to replace a microswitch, but I like this much better!
Dang!!!.... I just replaced the micro switch of my mouse.
