A mechanical switch is a type of electrical switch that uses physical moving parts to open or close a circuit. Unlike other switches, such as membrane or rubber dome switches, mechanical switches provide tactile feedback, allowing users to feel a click when pressed. This feature makes them popular in devices like keyboards, where precise input is essential. Mechanical switches come in various types, each offering different characteristics, such as actuation force and travel distance. Common types include Cherry MX switches, which are widely used in gaming keyboards, and Razer switches, known for their customizable options. These switches enhance user experience by providing reliability and responsiveness.
