N860/N86D codes

The following codes from the FKBnnnn model numbers and N860-nnnn-… part numbers. The first two digits are considered to indicate the series, e.g. FKB1234 would be taken as series 1200. However, Fujitsu have used series names comprising all four digits, as noted above — substantially more data is needed to get a clear picture. However, since series can comprise more series, then it may be that series using three or four of the digits are sub-series.

This data will help identify the type of switch found in a Fujitsu keyboard, so long as the N860 code is displayed on the outside.

Note that 2930 seems to be used by both leaf spring and lever action.

Unclear types

Lever action

Lever action (patent US 4803316 A) is a very rare Fujitsu switch. Keyboards with this switch found to date share the same case as FKB4700. Possible model codes include 1010 and 2930/2931, with the latter being in the same range as third-generation leaf spring. So far, no conclusive examples have been discovered, but tentative evidence suggests that it shared series 2930 with DIN dual-discrete leaf spring.
