Membrane Switch Keyboard Introduction
A membrane switch is a printed electronic circuit that uses
pressure to open and close a circuit. The membrane switch circuitry
is most often screen printed using conductive inks, which are
typically made of silver, carbon, and/or graphite.
Membrane switches are part of a range of devices considered to be
user interfaces (also called operator interfaces, or man-machine
interfaces) along with display-based touch screens, and mechanical
switches such as push-button, toggle, rocker, and slide switches.
The ultimate purpose of a membrane switch is to serve as the
interface between man and machine, enabling an operator to
communicate with a piece of equipment, instrument, or machinery.
Membrane switches can be manufactured with non-tactile switches,
which activate with 4 – 8 oz of touch pressure. Non-tactile
switches are less expensive and provide the longest switch life.
Tactile switches have a snap-action feel and may also be
incorporated into a membrane switch, enhancing tactile feedback,
but with a greater cost and lower switch life.

What are Membrane Switch Keyboard ?
The easiest way to understand what a membrane switch is, is to
reference an all-time favorite
device-the microwave. The membrane switch on the microwave is the
buttons—the human
interface layer—that communicates to the microwave that you’d like
to reheat your food for
one minute.
