KBK update for Tuesday, 6th August

All evidence now indicates that the switches used in Micro Switch RW Series keyboards are Micro Switch Series 7 [Micro Switch Series KB]. Micro Switch produced a number of switch series with numeric series names, with Series 2, Series 3, Series 4 and Series 6 being confirmed. The catalogue listing numbers of all these series follow the same pattern: the series number, then a classification letter, followed by additional letters and numbers. Series 7 appears to be a derivative of Series 3; both series use the same rail mount system. Like Series 7, Series 3 comprises both reed and non-reed types. Series 7 switches came in a variety of configurations, of which not all were suitable for keyboards, pointing to the series not being specifically intended for data entry keyboards.

Additionally, the keycaps for Micro Switch SW and SN Series and Micro Switch SD Series have been found to be 2SW Series. Although not confirmed by literature, all keycap part numbers appear to fit into this subseries, including those of illuminated switches.
