Ans: Mechanical switches are available in various types, including tactile, linear, and clicky switches. You should choose one depending on your preferences and needs, Tactile switches provide a tactile bump when the key is actuated, giving you a physical indication that the keypress has been registered. Linear switches have a smooth and consistent feel throughout the keystroke without any tactile bump. Clicky switches have both a tactile bump and an audible click, providing satisfying feedback. Consider whether you prefer a switch with or without tactile feedback based on your personal preference.
