Switch selection is where a keyboard’s character is decided. It is also the specification most frequently reduced to a single word on a product brief — “linear” — when the reality involves force curves, travel distances, spring weights, material choices and lubrication, all of which interact with the rest of the build.
This guide is written for brands deciding what goes into a product line, not for enthusiasts choosing a personal board, and it assumes the switches will be sourced from established supply chain partners including Cherry, Gateron, Kailh and Outemu-compatible manufacturers.
The Three Fundamental Types
Every mechanical switch belongs to one of three families, distinguished by what the user feels during the keystroke.
Linear switches travel straight down with no change in resistance until bottom-out. The force curve is a smooth, near-straight line. Nothing interrupts the stroke.
Tactile switches introduce a bump partway through the travel — a deliberate increase in resistance that peaks and then releases before bottom-out. The user feels a distinct point where the keystroke has registered.
Clicky switches produce the tactile bump plus an audible click, usually generated by a separate mechanism within the housing. They are the most distinctive and the most divisive.
Comparing the Three
| Characteristic | Linear | Tactile | Clicky |
|---|---|---|---|
| Force curve | Smooth, consistent | Distinct peak mid-travel | Peak plus audible event |
| Feedback channel | None until bottom-out | Tactile only | Tactile and audible |
| Sound level | Lowest | Moderate | Highest |
| Gaming suitability | Excellent — consistent rapid repeats | Moderate | Moderate |
| Typing suitability | Good | Excellent | Excellent for some |
| Shared-office suitability | Good | Acceptable | Poor |
| Market share in enthusiast segment | Dominant | Significant | Niche |
The dominance of linear switches in the enthusiast segment is not an accident of fashion. Rapid repeated presses on a linear switch encounter no resistance variation, which produces consistent and predictable input. This is why linear is the default for gaming-focused products and why the entire Hall Effect category is almost exclusively linear.
Reading a Force Curve
Switch specifications are most usefully understood through the force curve — a graph of required force against travel distance. Four numbers matter most.
Actuation force is the force required to register the keystroke, commonly expressed in grams. Typical ranges run from roughly 35 g for light switches to 60 g and above for heavy ones. Lower values reduce finger fatigue in long sessions; higher values reduce accidental presses.
Actuation travel is how far the stem must move before registering. Standard mechanical values cluster around 1.8–2.0 mm. Shorter travel — achieved through speed switches or, at the extreme, through Hall Effect firmware — registers sooner.
Total travel is the full stroke distance before bottom-out, typically 3.4–4.0 mm. This is what the user feels as the total depth of the keystroke.
Tactile bump position applies to tactile and clicky switches and describes where along the travel the bump occurs. Earlier bumps produce a snappier feel; later bumps feel more linear until the very end.
The relationship between actuation travel and total travel determines how much of the stroke remains after registration. A switch with a 2.0 mm actuation point in a 4.0 mm total travel has 2 mm of post-registration travel — the distance the key continues to move after the input has registered. Experienced gamers often prefer less of this, which is why shorter-actuation switches are popular for competitive products.
Beyond Type: What Actually Changes the Feel
Two switches of the same type from different manufacturers can feel substantially different, and the variables responsible are worth specifying explicitly.
- Spring weight and type. Progressive springs increase force as the key descends; linear-rate springs stay consistent. This changes the character of the bottom-out noticeably.
- Housing material. The plastic compound affects both sound and the smoothness of travel. Different materials produce measurably different acoustic signatures.
- Stem material and tolerance. Tighter tolerances reduce wobble; the material affects friction against the housing.
- Factory lubrication. Pre-lubricated switches are now the expectation at mid-tier and above. Lubrication quantity and application point have as much effect on feel as the switch design itself.
- Pin configuration. Three-pin and five-pin switches differ in PCB compatibility. Five-pin switches have additional plastic legs for stability, which require matching PCB support or must be clipped for three-pin boards.
That last point is a common source of avoidable customer frustration. If a product supports hot-swap and the PCB is three-pin, the keycaps and documentation should make clear that five-pin switches require the extra legs to be clipped before installation.
Matching Switch Type to Product Position
| Product position | Recommended switch type | Rationale |
|---|---|---|
| Competitive gaming | Light linear, pre-lubricated | Fast, consistent rapid inputs |
| Mainstream gaming | Medium-weight linear | Balanced for gaming and general use |
| Office / productivity | Light tactile, or silent linear | Feedback without excessive noise |
| Shared office / open plan | Silent linear | Noise is a genuine constraint |
| Enthusiast premium | Linear, with tactile option | Matches segment preference while offering choice |
| Retro / novelty | Clicky | The audible character is the product appeal |
One structural note for gasket-mounted products: the same foam stack that produces the desired cushioned feel also absorbs tactile feedback. The bump of a tactile switch is noticeably muted on a heavily damped gasket board, which is a real argument for pairing gasket mounting with linear switches rather than fighting the acoustic design.
Offering Choice Without Multiplying SKUs
Switch preference varies enough that offering only one option leaves sales on the table. The practical approach many brands take is to offer two switch options per product — typically one linear and one tactile — rather than attempting to cover the full spectrum. Two options serve the vast majority of buyers, keep SKU complexity manageable, and preserve inventory flexibility.
For hot-swap products, the calculation shifts. If the customer can change switches freely, the factory-supplied switch becomes a starting point rather than a commitment, and a single well-chosen linear default is often sufficient.
Newkra Technology sources switches across major supply chain partners and supports both soldered and hot-swap mounting configurations, with switch selection advice grounded in the target product position rather than a single preferred vendor.
