Editing Fujitsu FKB4700 (section)

==Description==
The [[rubber dome]]s of the FKB4700 are found in two sheets: one for the function key row, and one for the remainder of the keyboard. To account for differing locales and feature sets, the FKB4700 has more trace contacts and domes than is necessary for all variants. Removing the case lid of a UK ISO keyboard reveals the supernumerary trace contacts and domes: this includes three domes below Delete/End/Page Down, and a trace contact for \ when ANSI [[enter key|enter]] is selected.

The switch stabilisers are similar to those on [[IBM Model M]] keyboards, but are not particularly effective, meaning that most stabilised keys need to be struck directly above the switch. The space bar also has a small wire spring that sits on one end; its purpose is not clear, but it may be intended to increase the resistance.

Extremely unusually for a membrane keyboard, the FKB4700 series features integrated [[lock key|lock]] [[LED]]s. This is achieved by mounting the LEDs into the slider shaft plate, and by placing conductive rubber sleeves around the base of the LED pins. This allows the LEDs to make conductive contact with the top membrane without the need to apply solder.

Numbering inside the case suggests that the same case was used for keyboard lines numbered 1000, 4700 and 2931, but the other two product lines do not appear to exist.
