How to fix broken middle mouse button

Last Updated: Feb 17, 2024 by

The middle mouse button is an essential tool for many computer users. It allows for easy scrolling, opening links in new tabs, and closing tabs with a simple click. However, like any other mechanical component, the middle mouse button can break over time. This can be frustrating, but fear not, there are ways to fix a broken middle mouse button.

Clean the Mouse

Before attempting any repairs, it’s important to make sure that the issue is not simply due to a dirty mouse. Over time, dust and debris can build up inside the mouse, causing the middle button to become stuck or unresponsive. To clean the mouse, turn it upside down and gently tap it to remove any loose debris. Then, use a cotton swab dipped in rubbing alcohol to clean around the middle button. Allow the mouse to dry completely before testing it again.

Check for Software Issues

Sometimes, a broken middle mouse button can be caused by software issues rather than a physical problem. Make sure that your mouse drivers are up to date and that there are no conflicts with other programs. You can also try resetting your mouse settings to their default values. If the issue persists, it’s likely a hardware problem.

Open the Mouse and Check for Loose Parts

If cleaning and checking for software issues did not fix the problem, it’s time to open up the mouse and take a look inside. Use a small screwdriver to remove the screws on the bottom of the mouse. Carefully remove the top cover and check for any loose parts or debris that may be causing the middle button to malfunction. If you find any loose parts, reattach them and test the mouse again.

Replace the Switch

If the middle button is still not working, the issue may be with the switch itself. You can purchase a replacement switch online or from a computer repair shop. To replace the switch, you will need to desolder the old one and solder the new one in its place. This can be a delicate process, so it’s best to have some experience with soldering before attempting this fix.

Use a Software Solution

If you’re not comfortable with opening up your mouse or soldering, there are software solutions that can help fix a broken middle mouse button. Programs like X-Mouse Button Control allow you to remap your mouse buttons, so you can assign a different button to act as the middle button. This can be a temporary fix until you are able to replace the switch or purchase a new mouse.


A broken middle mouse button can be a frustrating issue, but with these tips, you can try to fix it yourself before resorting to purchasing a new mouse. Remember to always be gentle when handling your mouse and to take proper precautions when opening it up. If all else fails, it may be time to invest in a new mouse.
