There are several reasons behind a double-clicking mechanical keyboard. Getting to know the causes can be a remedy itself as you may think of solutions or know how to prevent it from happening.

Dust or other debris

Most of the time dust or ‘alien’ objects under the keycaps is the main criminal for your keyboard double typing. The keyswitches cannot run perfectly if there is a thick layer of dust or strange things get in their way. Dust and other debris also cause other problems to your keyboard and degrade your keyswitch longevity.

Defective switches

Cheap switches, old switches, or damaged switches may not allow your typing experiences to happen as normal. A problem within the springs or metal leaves inside a mechanical switch can make the keyboard chattering happen often.

Outdated keyboard drivers

Forgetting to update your keyboard driver can be one of the reasons. An outdated driver can not keep up with your computer and hence, bad communication between the keyboard and a processor happens, or a hole in the keyboard security is born.
