What Cause Keyboard Double Typing?

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Outdated keyboard drivers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 An outdated driver can not keep up with your computer and hence, bad communication between the keyboard and a processor happens, or a hole in the keyboard security is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.

Rough Usage
If you tend to go hard on your keyboard when typing or drop it several times, the issue of keyboard double typing is likely to happen. Rough handling can cause physical damage to the fragile components of your keyboard, especially if your keyboard is made with cheap and flimsy materials.
Incorrect keyboard settings
The double typing problem can be due to your keyboard setting. Low-tech users may not aware of the hard-drive settings, so you may set or do not know it’s set wrongly. For example, setting a long repeat delay can make the keyboard produce more than one character with a single press.
Sometimes, you may want to remap your keyboard for the best personal customization. If that’s true, check out our article here on how to remap your keyboard.
High temperature
Not many people are aware of this reason since it is not a big factor. But, a too high temperature can result in the keyboard double typing, so it’s worth noticing.
