Overview of Mercury USB Keyboard:
When you look at all the extras and options that are available for new computer keyboards, it can be hard to believe that their original design came from mechanical typewriters that didn't even use electricity. Now, you can buy Mercury USB Keyboard that bears little resemblance to flat, rectangular models with ordinary square keys. Some flashier models light up roll up or fold up, and others offer options for programming your own commands and shortcuts. But no matter how many bells and whistles they offer, most keyboards operate using similar technology. They use switches and circuits to translate a person's keystrokes into a signal a computer can understand. When you press the key, the bar pushes down through the hole to touch the contact layers below. Inside the hole, there's a little tiny piece of rubber that stops the key moving down and pushes it back up when you release it. This is what gives the spring to the keys. Mercury USB Keyboard have a plastic keys and contact layers which are just two parts. On top, there's the keypad part with all the keys molded from a single piece of flexible (rubbery) plastic. The underside of each key is coated with a small patch of electrically conducting material. The second part of the keypad is a layer of electrical contacts formed directly onto a circuit board. When you press down on the Mercury USB Keyboard key, the conducting material bridges the contacts, completes a switch, and triggers the specific circuit for that key. The problem with keypads like this is that you get oily films or dirt building up between the two layers, which can stop one or more keys from working. They also feel very "squidgy" to the touch, which makes them unsuitable for ordinary computer keyboards.
