===Nomenclature===
Micro Switch keyboard and keyboard switch part numbers ("catalog listing" numbers) generally contain the two-letter series name in the middle. For keyboards, the digits to the left of the series name give the number of keys on a keyboard. For example, the 66-key [[IBM 3277 typewriter keyboard]] (part of [[Micro Switch SW Series|SW Series]]) has catalogue listing number 66SW6-4, while the [[Micro Switch SC Series|SC Series]] 92-key [[ITT Courier 1700]] has catalogue listing number 92SC40-23. To the right of the series name are characters that give the keyboard design a unique identity.

For switches, the digits before the series name vary by series. For SW Series, the digit 1 is used, presumably on the basis that there are no one-key keyboards; an example is 1SW12-BL, a switch found in the IBM 3277 typewriter keyboard. For [[Micro Switch SD Series|SD Series]], the number 1001 is used instead, but these digits and the series name are both omitted from the switch; for example, switch type 1001SD4B3E is labelled simply "4B3E" in the space available. [[Micro Switch SN Series|SN Series]] uses 101SN* and 201SN*, which suggests that these were never used in full-size keyboards.

===Switches===
Micro Switch's first Hall effect solid-state switch was introduced in 1965. This was followed by what they claimed was the world's first solid-state keyboard, in 1968.<ref name="History" /> This is likely to be [[Micro Switch SW Series]].

The most commonly-occurring switch series is "Honeywell Hall Effect", [[Micro Switch SD Series]]. SD Series itself covers both the keyboards and the switches it used. Micro Switch produced other ranges of [[Hall effect]] switches as well as reed keyboard switches.

===Keycaps===
Some keycaps have some odd properties such as this Caps Lock LED keycap (Switch Model 12B3S). Honeywell Hall Effect keycaps are known to be exclusively double-shot, using very thick plastic in all cases. While the switch isn't in production anymore, there were many variants of the switch, with a specific naming scheme to the models.In almost all standard variants of the switch, there is a spot for a LED add-on part as seen in the Convergent 64-00164 keyboard.
