Chiclet keyboard

A chiclet keyboard is a computer keyboard with keys that form an array of small, flat rectangular or lozenge-shaped rubber or plastic keys that look like erasers or "Chiclets", a brand of chewing gum manufactured in the shape of small squares with rounded corners. It is an evolution of the membrane keyboard, using the same principle of a single rubber sheet with individual electrical switches underneath each key, but with the addition of an additional upper layer which provides superior tactile feedback through a buckling mechanism. The term "chiclet keyboard" is sometimes incorrectly used to refer to island-style keyboards.^{[citation needed]}

Since the mid-1980s, chiclet keyboards have been mainly restricted to lower-end electronics, such as small handheld calculators, cheap PDAs and many remote controls, though the name is also used to refer to scissor keyboards with superficially similar appearance.
