High Quality Content by WIKIPEDIA articles! A chiclet keyboard or island-style keyboard is a computer keyboard built with 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. Most often the tops of the keys were hard, but sometimes they were made of the same material as the rubber dome itself. For example, the keys on Sinclair ZX Spectrum computers were "rubber dome keys" which were sometimes described as "dead flesh", while the "American" version of the Timex Sinclair 2068 was described as having "chiclet keys". Chiclet keyboards are characterized by having each key surrounded (and held in place) by a perforated plate, so there is a space between the keys.
