Reasons Behind Keyboard Malfunctioning

There are several reasons behind the keyboard malfunctioning. Some of the common reasons are:

There are many different types of keyboards, including:

While high-end keyboards, mechanical switches are the oldest type of switch. Their durability and precision make them popular, but they’re noisier than other keyboards.

Most keyboards use rubber domes under the keycaps to provide tactile feedback when pressed down. These keyboards are cheaper but can wear out faster than other styles due to the constant pressure of fingers pressing down on each keycap repeatedly over time. 

Some keyboards also include built-in LED backlights for easier visibility in dark environments.

Components of keyboards

Every key of the keyboard has three components a keycap, a keypad and a key retainer. Keycaps are visible on keypads, which act as mechanical buttons, and key retainers provide support to hold the keypad and keycap in place.
