Keyboards and switches by year

From Deskthority wiki
Jump to: navigation, search

Year ranges only indicate the earliest and latest known dates, e.g. the first and last dates marked in the case mouldings. Controller dates are preferred as they should be a closer match to switch selection, while multiple switches may share the same case moulding.

For Hi-Tek Series 725 switches, see NMB Hi-Tek variants.
