How to fix a mouse button

Mouse usually malfunction after excessive clicks. The problem usually occur at the left click button since it is pressed most often, other time is the wiring problem at the end closer to the mouse. Shopping for new mouse become hobby to some fellas.

I am also one of the 'victims' to this 'unavoidable' problem, therefore I also have a lot of mouse. Each one last me around 2 years. Wireless mouse nowadays only use one battery cell, I guess there are some sort of charge bump integrated inside the optical chip, it generate the Voltage needed for LED.

Today, the one with nano receiver fail. In fact I like this mouse very much, even if it beyond repair, I guess I will get back the same one. So I have decided to open it up and see what can I do. I used LASER mouse before, all the while people say how accurate is laser mouse. Apart from it invisible light, I really can't sense any differences in term of performance, I guess the error arise from human hand consistency is anyway larger than the error of any optical mouse.

I never realized that get it fixed is just a piece of cake before.

Just cut some fine sand paper into a stripe.

Then rub the metal contact, just 2-3 round is okay, because the oxide layer is very thin, must rub all four side of the contacts.

Measure both the end pin, it should measure zero ohm (my meter have some error, so it measure 2.2ohm). If the contact is poor, it will measured several decade kilo-ohm. This two pin is normally closed, press the button it resistance will become infinity, one of then with the top button on it will be connected to the middle.

After assemble everything back, it work just fine, I am glad I get a good working mouse back.

The End
