What is A Tactile Switch Keyboard?
Tactile Switch Keyboard are generally made from five different layers. This includes
membrane,
graphic, tactile, rigid and static layers. The first layer contains
the graphic interface for the
user to control the machine. It can also include a flexible circuit
for less expensive
alternatives. Another layer will contain the printed circuit which
allows a signal to be
transmitted. The ink that is used for the printing on the circuit
is generally made up of a
variety of metals. This helps for the signal to be conductive for
turning on and off. Membrane
switches allow for communication to take place in electronic
devices. Membrane switches are
a piece of equipment that can be highly sophisticated or rather
simple by design.
