Keyboards and switches by year

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.
