Connection
There wired connection type and wireless type . Like the general office , play games and select cable type , wired keyboard connected to a computer , there are two : USB and PS / 2.

So choose waterproof , ultra-thin keyboard is also a popular market , which is characterized by a key way short, quick response, and generally occupy a small space , very delicate !
Overall structure

Each has its own specific purpose , this with personal habits , like there are a lot of big series . So , different people , different cultures , different purposes , and finally select the keyboard is not the same . They differ mostly in the primary key of each zone bottom line . Alt, Ctrl, Win, Fn,, how much order.
Sense of touch
1, in the tone of the keyboard when you can take a look by hand , listening to the sound size and feel of a keyboard under every sense of touch by going after .
2 , pressure grams , this value generally refers to the pressure needed to press the key number of grams , usually from 35g ~ 60g are, feel the impact of this value is quite large , of course, there is the pressure curve .
The choice of materials
Keyboard keycap material selection is critical , the main material of relatively good ABS, POM, PBT three, including ABS cheapest, but long-term use is easy to shine. Three materials in the performance feel all have their own characteristics , in general are good.
1, ABS: keycap most common materials, petroleum associated index of 100 ! ABS chemical name for acrylonitrile – butadiene – styrene plastic , is one of five synthetic resin.
2, PBT: expensive keyboard materials, petroleum associated index 40 ! PBT chemical name is poly (butylene terephthalate) , is made through the mixing process milky translucent to opaque , crystalline thermoplastic polyester resin.
3, POM: super wear light-colored keyboard material , petroleum associated index 20 ! POM POM chemical name , English name :. Polyoxymethylene (Polyformaldehyde POM is a side-chain , high-density, high-crystalline linear polymer .
Personalized keyboard
Now personality is really very high atmospheric keyboard on the grade ! There are many keyboard concept , we are looking forward to have a listing of which God hurry ! Backlit keyboard , transparent keyboard , ultra-thin soft keyboard , keyboard pattern shape , even some metal keyboard , for those of us pursuing appearance appearance association is definitely too cattle friends.
Volume size
The volume sizybe keoard but I fully understood , because usually used to the laptop keypad, switch to desktop keyboard is not suited , large keyboard , and has become accustomed to playing finger keypad, often the wrong word , this time Select a small desktop keyboard , it would be too easy

By Application
Applications can be divided according to the desktop keyboard , laptop keyboard , industrial keyboard , Sulu keyboard, dual-control keyboard , ultra keyboard six categories.
By nature symbols
According to the nature of symbols can be divided into alphabetic keyboard and numeric keypad into two categories. Dual USB keyboard , a keyboard can control two computers , a key for 2 seconds to switch quickly and easily. Classified according to the principleACER 2020 series Replacement Laptop Battery
1 . Mechanical keyboard (Mechanical) using a similar metal -contact switches , the working principle is to make
Contact on or off with a simple process , noise , and easy maintenance.
2 . Internal plastic membrane keyboard (Membrane) keyboard is divided into four , achieved without mechanical wear. Which is characterized by low prices, low noise , and low cost , have occupied most of the market share.3 . Conductive rubber keyboard (Conductive Rubber) contact is connected through the conductive structure of the rubber . Internal keyboard with a layer of conductive rubber bump charged , each key corresponds to a bulge, while pressing the following contacts connected . This type of keyboard is a transitional product market by a mechanical keyboard membrane keyboard to . 4 . Non-contact capacitance keyboard (Capacitives) capacitive switches using a similar principle , the distance between the electrodes causes the capacitance change to drive change through the encoder button . Feature is no wear and tightness better.
Classification by text input
Press text input while hitting the number keys can be divided into one-touch input keyboard , double and multi-key input keyboard input keyboard , now we used the keyboard are touch input keyboard, Sulu keyboard is a multi- key input keyboard, the latest in the four are double input method keyboard input keyboard.ACER 2020 series Replacement Laptop Battery
Conventional classification
Conventional keyboard has mechanical buttons and capacitive buttons two kinds. IPC keyboard in the film there is a touch of the keyboard keys . Mechanical keyboard is the first structure to be adopted , the general principle is similar to metal contact switch is turned on or off to make contact with the process is simple , easy maintenance, the general feeling , noise, wear characteristics , most inexpensive mechanical the keyboard uses copper spring as the elastic material , copper , easy to break and easy to lose elasticity , the failure rate increased use over time , and now has basically been eliminated , replaced by a capacitive keyboard . It is based on capacitive switch keyboard , the principle is the distance between the electrodes to generate the change of capacitance is changed by the key , allow the temporary formation of shock pulse condition . Theoretically this switch is a non-contact non-contact , wear rate is negligible even minimal , there is no bad risks , with low noise , easy to control touch, you can create high-quality keyboard , but the process than the mechanical complex structures . There is also a keyboard for the IPC to be completely sealed membrane keypad with touch only for special occasions.
