When you press a key on a standard keyboard, this is what happens: the key to pushing a rubber dome, which is then "flattened" to make contact with the plastic circuit board. They are called dome-rubber keyboards. In most portable keyboards and desktop keyboards slim profile, use small plastic interlocking tabs that bend when pressed, they are called scissor switch keyboard. Most keyboards as you can see, do not use a real reliable switch, but using these systems can fail intermediation may eventually feel "heavy", and provide tactile feedback to the typist inconsistent. A variety of switches that can be found in high-quality mechanical keyboards. They are divided into three main categories, Cherry MX, the Alps and in the spring of buckling.
The Cherry MX change the style, which is produced by the Corporation Cherry Germany, stems key uses different colors to denote different features of key switch. Blues Cherry MX that provide tactile and audible click when pressed, the tactile sensation to Browns, but has a softer sound to use quieter, and blacks lack a tactile sensation and the use of a linear action when the pressures of fast keys are crucial.
ALPS switch is made by Alps Electric Company of Japan. There are many variations of the Alps keyswitch, the most common of which has two types: Complicated and simplified. The ALPS complications occur in similar varieties to the Cherry MX, one with a tactile and audible click, one with a tactile sensation, but a softer sound, and finally, one with a linear action, which not have the feel of their peers. The simplified ALPS has four types, type I, II, III and IV. The most common modern mechanical keyboards use a simplified variation on the type I. One can find a white version that has the tactile and audible click, and a version of Black, which has a tactile feel, but a softer sound.
The last exchange, spring deflection, is a throwback to the infamous IBM Model M that made him famous. As the name suggests, the switch works when the key pressure on a spring that is under pressure from below, until finally buckles under the pressure spring, allowing the key to be pressed. Then, once released, the spring regains its original shape. Although this type of key switch and not commonly found on modern keyboards, it is important to understand that this all began.
Modern mechanical keyboards used perfectly designed high-performance switches help eliminate the stress of writing and provides the audio and tactile stimuli that lets you type faster and more efficiently. The only drawback is that after using a mechanical keyboard, which goes back to a cheap "heavy" rubber dome keyboard looks like torture.
