Keyboard switch types explained
Linear, tactile, clicky, optical, magnetic, membrane — what each one does under your finger, and which to pick for typing or gaming.
Our pick: Linear for gaming, tactile for typing, Hall-effect if you want both plus rapid trigger
Keyboard switches are the single decision that changes your daily experience more than any other specification, and they are also the most poorly explained. Colour names like red, brown, and blue are conventions rather than standards, and two switches with the same colour from different brands can feel entirely different.
| Type | Feel | Best for | Downside |
|---|---|---|---|
| Linear (reds) | Smooth, no bump | Gaming, quiet offices | Little feedback while typing |
| Tactile (browns) | Bump, no click | Typing, all-round use | Some find the bump vague |
| Clicky (blues) | Bump plus audible click | Typists who love feedback | Loud in shared spaces |
| Optical | Light-actuated, often linear feel | Gaming, long life | Limited aftermarket choice |
| Hall-effect magnetic | Adjustable actuation depth | Competitive gaming | Cost, and less pleasant for typing |
| Membrane | Soft, mushy, long travel | Budget and low-profile boards | No feedback, wears out as one unit |
The three mechanical classics
Linear switches travel smoothly with no tactile event, which makes them quiet and fast — the default for gaming. Tactile switches add a bump you can feel without an audible click, and they are the most popular choice for typing because your fingers can confirm registration without the key bottoming out. Clicky switches add a deliberate click on top of the bump, delivering the strongest feedback and the loudest noise.
Where optical and magnetic differ
Optical switches actuate when a beam of light is interrupted, removing the physical contact that wears out — which is the same durability argument optical mouse switches make. Hall-effect magnetic switches go further: because they measure travel continuously, actuation depth is a setting. That enables rapid trigger, and it is why RTINGS rates a magnetic board as the best gaming keyboard it has tested.
Membrane is not automatically bad
Rubber dome boards are cheaper, softer, and quieter, and a good low-profile membrane keyboard is the right answer for many desks — Logitech's MX Keys S is a genuinely excellent typing keyboard. What membrane cannot offer is switch choice, repairability, or that crisp mechanical feel. The trap is paying mechanical money for one, which our gaming keyboards to avoid guide covers.
Switches are the one keyboard specification you will notice every single day.

The verdict
Buy linear switches for gaming and quiet workplaces, tactile for typing, and clicky only if you are alone and enjoy it. Choose Hall-effect if competitive input matters, and a good low-profile membrane board if quiet comfort is the priority. Our best mechanical keyboards guide lists boards with hot-swap sockets, so the decision stays reversible.
Questions we get
What are the main keyboard switch types?
Mechanical switches divide into linear (smooth travel, no bump), tactile (a bump you can feel without an audible click), and clicky (a bump plus a pronounced click). Beyond those sit optical switches, which actuate with light; Hall-effect magnetic switches, which measure travel and allow adjustable actuation; and membrane or rubber-dome boards, which are the cheapest and softest.
Are linear or tactile switches better for typing?
Tactile, for most people. The bump gives your fingers confirmation that the key has registered, which reduces accidental key presses and bottoming out. Linear switches are smoother and quieter, and many people prefer them for gaming, but for long typing sessions tactile feedback is the more common preference.
Are clicky switches annoying?
To everyone in the room, yes — and sometimes to the typist. Clicky switches combine a tactile bump with an audible click, which provides the strongest feedback of the three. They are the defining choice for people who like them and unusable in shared offices, open-plan homes, or next to a sleeping partner. Silent tactile switches are the compromise.
What makes Hall-effect switches different?
They measure how far the key has travelled magnetically rather than actuating at one fixed point, so actuation depth becomes a setting. That enables rapid trigger — resetting a key the instant you begin lifting rather than at a fixed release point — which is why competitive players favour them. A conventional mechanical switch cannot do either.
