“A membrane keyboard is a keyboard design that utilises a flexible, pressure-sensitive membrane as its key mechanism. In contrast to mechanical keyboards with individual switches for each key, membrane keyboards use a continuous, sealed membrane layer with pressure pads beneath the keys. When a key is pressed, the membrane deforms, establishing a connection that registers the key-press. Known for their quiet operation and slim profile, membrane keyboards are commonly found in various devices such as computer peripherals, household appliances, and industrial control panels. While lightweight and cost-effective, some users may prefer the tactile feedback provided by mechanical keyboards, which use physical switches for a more distinct and responsive feel.”
