Specification:
Capacitive keyboard
"In this type of keyboard, pressing the key changes the capacitance of a
pattern of capacitor pads. Unlike "dome switch" keyboards, the pattern
consists of two D-shaped capacitor pads for each switch, printed on a
printed circuit board (PCB) and covered by a thin, insulating film of
soldermask which plays the role of a dielectric. The mechanism of
capacitive switches is very simple, compared to mechanical ones. Its
movable part is ended with a flat foam element (of dimensions near to a
tablet of Aspirin) finished with aluminium foil below. The opposite side
of the switch is a PCB with the capacitor pads.
When a key is pressed, the foil tightly clings to the surface of the
PCB, forming a daisy chain of two capacitors between contact pads and
itself separated with thin soldermask, and thus "shorting" the contact
pads with an easily detectable drop of capacitive reactance between
them. Usually this permits a pulse or pulse train to be sensed. The keys
do not need to be fully pressed to be fired on, which enables some
typists to work faster."
