Key switches are essential components in keyboards, determining how they feel and respond when pressed. The most common types include mechanical, membrane, and scissor switches. Mechanical switches offer tactile feedback and durability, making them popular among gamers and typists. Membrane switches are quieter and often found in budget keyboards, while scissor switches provide a low-profile design, commonly used in laptops. Each switch type has its unique characteristics. For instance, mechanical switches come in various styles, such as Cherry MX or Razer, each with different actuation forces and sounds. In contrast, membrane switches use a pressure pad system, resulting in a softer feel. Understanding these differences helps users choose the right keyboard for their needs.
