Membrane keyboards are a type of keyboard that uses a thin, flexible membrane layer to register key presses. Unlike mechanical keyboards, which have individual switches for each key, membrane keyboards rely on pressure pads that connect with a circuit when pressed. This design makes them generally quieter and more affordable. These keyboards are often found in budget-friendly devices and are popular for casual use, such as in laptops and home computers. While they may not provide the same tactile feedback as mechanical keyboards, they are lightweight and easy to clean, making them a practical choice for many users.
