Your keyboard is the thread that connects you to your laptop. The way in which a keyboard feels—from the sensations of every key urgent down and resetting to the construct of the board’s chassis—has a direct influence in your typing expertise, affecting accuracy, velocity, and fatigue.
We’ve dug into the fun of quality keyboards and the thrills of customization at Ars Technica earlier than. However what actually makes one kind of keyboard really feel higher than one other? Folks say membrane keyboards really feel mushy, however why? And what about keyboards with cult-like followings? What makes decades-old IBM keyboards or costly Topres so particular?
On this information, we’ll take a look at how a number of the hottest keyboard classes work and the way their variations influence typing really feel.

Mechanical keyboards
Many individuals contemplate mechanical keyboards to be the king of keyboards. Mechanical keyboards are usually very tactile, as their keys provide distinct suggestions with every press. Customization choices that influence really feel, look, and sound imply that mechanical keyboards are additionally nice for customers who need to tweak particular person components to get the exact really feel they’re in search of.
So why do they really feel so good to kind on? Let’s have a look.
The swap beneath every mechanical keyboard key has extra elements, shifting components, and journey in comparison with a membrane keyboard, making button presses really feel extra substantial. Urgent a mechanical swap sends its plastic stem downward, whereas the spring supplies resistance. Because the plastic stem strikes downward, it permits the swap’s two metallic leaves to make bodily contact, closing a circuit and sending a sign to the keyboard’s printed circuit board, or PCB. (Take a look at this article from Kinetic Labs for an summary of the fundamentals of mechanical keyboard PCBs). Relying on the stem’s design, the keypress may go down easily (in linear switches), with a discernible bump alongside the way in which (tactile switches), or with a bump and a click on sound (clicky switches).

When the button is launched, the spring creates suggestions whereas the important thing resets, throughout which the plastic slider comes again up vertically and separates the swap’s metallic leaves once more.
That’s how mechanical switches normally work, however some fashionable examples tweak that formulation, akin to optical switches (which actuate relying on if the swap’s stem travels by means of a light-weight beam) and Hall effect switches. Moreover, Varmilo produces switches that work like a normal mechanical swap, however as a substitute of actuating through metallic contact factors touching, the metallic factors simply come very shut to one another throughout keystrokes. This modifications the electrostatic capacitance of the electrical subject between the 2 contacts, leading to enter (these electrostatic capacitive switches work in a different way from Topres, which we’ll get into later).

Mechanical keyboards additionally present customization choices that make it simpler to fine-tune the typing expertise. Mechanical keyboard customization choices embody swap kind, keycap sizes, shapes, and materials; various kinds of instances, gaskets, and plate mounting types; and purposes of froth, lube, and stabilizers. Typical membrane keyboards do not enable for this sort of personalization.
Some individuals additionally discover that the suggestions and journey of mechanical keys assist with the physical discomfort related to frequent typing. And whereas firms typically market the brief key journey of scissor switches as a approach to kind sooner, mechanical switches also can assist with velocity and accuracy due to their distinct keys and tactility. (We’ll take a look at scissor swap keyboards in a bit.) Additional, some mechanical switches require little power and/or journey to actuate, which might additionally assist with velocity and the quantity of power exerted whereas typing.
