When we talk about gaming
keyboards, the first distinction we find ourselves making, regardless of the
use for which it was designed, is with regards to the technology of the keys
with which it was built.
The two most common key
technologies are the mechanical ones from which the name mechanical keyboard
derives and the membrane ones from which the membrane keypad.
Over time, the membrane
switch manufacturers began making changes to the keyboards, trying to
improve them and make them unique by modifying the switches, adding
backlighting, macro keys, software complexes, etc.
As a player and blogger, the
keyboard is a fundamental component of my work tools and if we add a passion
for technology and a great curiosity for new things, you can imagine how many
models have tried in these 25 years of PC career.
Every keyboard we have
tested turned out to be different, regardless of whether or not they have the
same switches, each model has its advantages and disadvantages, each being more
or less suited to my way of writing or playing.
What is a membrane keyboard?
With the term membrane
keyboard, we tend to categorize all those keyboards made up of layers or
flexible layers in which, unlike mechanical keyboards, the keys are not divided
among themselves but are all part of a single flexible surface that depending
on the pressure that we exercise will send the single impulse.
The first layer called the
upper layer of the membrane is the one that shows the letters and numbers, each
letter or number has in its lower part a part in a conductive material,
separated from the other symbols.
The second layer is the one
that separates the upper layer from the lower one.
The third lower layer has a
conductive trace and collects and sends impulses to the system.
When we press the button,
the first layer will flex and the conductor under the button will touch the
bottom layer and create a contact.
The conductive trace on the
lower layer is as if it were a map and based on the position of the contact an
impulse relative to the specific position and therefore to the letter or symbol
will be generated and recorded by our PC.
Benefits of membrane keypad:
• They are Silent: The noise produced while
typing is almost zero and is not annoying for roommates.
• They are Economic: The materials used in
the construction are cheap and easy to produce.
• They are dirt-resistant: the compact design
and the few spaces between the keys prevent dirt from entering.
• They are light: the use of mostly plastic
materials makes these keyboards light and easy to carry.
