For those of us who spend all our lives at our desks, choosing the best keyboard is nothing short of crucial. This is the tool that we use to complete our work, search for necessary information, and communicate with friends. So it’s odd when we tend to neglect the keyboards. Finding a keyboard that works the best for you is just a matter of patience.
However, membrane keyboards are becoming increasingly popular these days. They live up their name by featuring a membrane-like design rather than separating moving keys. The keyboards are now used in nearly every commercial industry, including information technology, medical, telecommunication, retail, and more. Unlike standard mechanical keypads, membrane keyboards are comprised of pressure pads with printed symbols and letters on the surface.
Today, we are going to take a closer look at the membrane keyboards, revealing four fun facts about them and how they work.
They Have Three Layers
Membrane keyboards are designed in a wide variety of configurations, each of which has its own unique properties and characteristics. Most membrane keypads feature three layers. The first and third layer consists of conductive traces and the middle layer is a space that consists of air or some other inert gas or material. The middle layer has holes in which the keys get pressed, thus, separating the other two outer layers.
Available Early in Home Computers
Some people assume membrane keyboards to be a new phenomenon, first making an appearance in industrial devices and machines. But the fact is, they have actually been around for several decades from now. When searched on Wikipedia, membrane keypads were even first found to be used in some of the first home computers, dating back to the early 1980s. Since then, they have made their way into various other applications, including household appliances, consumer devices and more.
Function via Electronic Switch
Membrane keyboards are essentially a type of electronic switch. This means, upon pressing a key it completes the circuit. And using this circuit, the connected device identifies which key was pressed.
Protection from Debris and Moisture
One of the greatest reasons that make the membrane keyboards the most popular and preferable choice of input for electronic devices is their natural resistance to moisture, dust, debris, and dirt. The fundamental design of the membrane keypad protects against the intrusion from such elements.
