Keyboard
Introduction
One of the main forms of user interface. You probably used one just now to get here!
Keyboards are a staple of any build and are often considered as a secondary peripheral not worth the hard-earned cash. This is not so. Keyboards sit between you and your computer; like any normal member of this society, you spend a significant amount of time at your keyboard. It only makes sense to make sure that you are typing on the most efficient, comfortable, and durable piece of equipment you can get your hands on as it will likely outlast any single build you own.
Comfort plays a key role in deciding the kind of keyboard one should purchase - it should not be something that people "grow in" to. Everyone has different requirements and tastes with regards to their typing experience. People with finger or joint problems may find it significantly uncomfortable to be typing on a keyboard with high force requirements, while others who type with the force of a jackhammer may find it painful over the long run to type on a keyboard with low force requirements.
In this section we will be using a few keywords in particular, so it would do one well to be acquainted with the following:
- Keystroke - This is the standard down-and-up movement of a key, following the depress-and-release movement of the finger. To press the letter "f" on the keyboard one time, the movement required for that specific key to type the letter "f" is known as a keystroke.
- Actuation - This will refer to the standard process of movement of the key. A cover-all term, actuation may include components such as the actuation force, switch movement, operating point, pressure point, and the reset point. Only actuation force and switch movement will be used extensively in this section.
- Actuation force - This refers to the amount of force or pressure one's finger must exert on a switch before the switch actuates and registers the keystroke.
Mechanical Keyboards
Form factor
Keyboards come in a variety of form factors, choose the one that's right for your needs.
Full-size
104 keys. Has everything on it but is often much too large for most people's personal uses.
TKL
87 keys. A more reasonable form factor that removes the number pad cluster on the right hand side.
60%
61 keys. Removes the function, arrow, and navigational key clusters. Most suitable for those looking for a more portable board without too many compromises.
40%
47/48 keys. Most of the boards you'll find here are community-made (although the Vortex Core is a notable exception).
Switches
Switches are the individual keys in a mechanical keyboard. They are individually packaged, making repairs straightforward if one stops working. All you need to swap switches out is a bit of soldering equipment (unless you have a hot-swappable pcb) and finesse. So who makes these switches?
Cherry
By far and away the most popular switch used by mechanical keyboard manufacturers, they are well known for their 50 million keystroke durability coming in a variety of flavours to suit most needs.
