The specific reasons for mechanical keyboard key damage are as follows:

Long-term use: Long-term use will gradually reduce the service life of mechanical keyboard keys, which can lead to key damage.

High frequency of use: High frequency of use is also one of the reasons for mechanical keyboard key damage. Because the keys are frequently used, the friction force increases, which can ultimately cause key failure or malfunction.

Key damage or loosening: If the keys of a mechanical keyboard are damaged or loosened, it can cause the keys to not bounce back properly or have a delayed bounce back.

Improper cleaning: If a mechanical keyboard is not cleaned properly, dust or other debris can accumulate in the gaps between the keys, which can affect the normal operation of the keys.

Liquid ingress: If liquid enters a mechanical keyboard, it can cause a short circuit or corrosion of the circuit board, resulting in key failure or malfunction.

Manufacturing quality: Poor manufacturing quality of a mechanical keyboard, improper coordination between components, and less durable materials can also cause key damage.

To avoid mechanical keyboard key damage, it is recommended to regularly clean the mechanical keyboard, avoid liquid ingress, and avoid prolonged continuous use. In addition, choosing a high-quality mechanical keyboard can also reduce the occurrence of key damage. If key damage has already occurred, it may be necessary to replace the keys or the entire keyboard, or seek professional repair assistance.
