If you have ever upgraded from a standard office keyboard to a mechanical one, then you’ve felt the difference immediately. The precision. The consistency. The sound. The control.
At the centre of that experience is one critical component: the Mechanical Keyboard Switch.
For gamers chasing milliseconds, developers typing thousands of lines per day, and professionals building premium workstation setups, switch selection is not a minor detail, it’s the foundation of performance. But in Australia’s growing custom keyboard community, understanding switches is the difference between owning a keyboard and engineering one.
Here is your complete mechanical keyboard switch guide, designed to help you understand what truly matters and choose with confidence.
What is a Mechanical Keyboard Switch?
A Mechanical Keyboard Switch is an individual, spring-loaded mechanism installed beneath each keycap in a mechanical keyboard. Every key has its own dedicated switch, giving it independent actuation and reset behaviour.
- A housing (top and bottom)
- A stem
- A spring
- Metal contact leaves
- Optional factory lubrication
When you press, the stem moves downward, compressing the spring. At a defined actuation point, electrical contact is made registering the keypress.
The result is:
- Faster and more consistent actuation
- Greater durability (often 50–100+ million keystrokes)
- Superior tactile and acoustic feedback
- Customisable performance characteristics
In custom mechanical keyboard builds, switches are chosen deliberately, not incidentally.
How Mechanical Keyboard Switches Actually Work
To understand switch performance, you need to look deeper than “smooth” or “clicky”.
The Core Components
1. Housing
- The housing encases all internal components. Materials matter:
- Nylon housings often produce a deeper, muted sound.
- Polycarbonate housings create a brighter, sharper acoustic profile.
- Tighter mold tolerances reduce stem wobble and increase stability.
Premium mechanical switches focus heavily on housing precision, but not all are created equal. Things to consider are the plastics shrinkage rates, and molds wearing out.
For our AEBoards MX switches, we own the molds and use them for our bespoke runs – in an effort to control quality and ensure that we don’t wear down our molds and keep our tolerances tight.
2. Stem Design
The stem determines movement feel and tactile profile. Subtle changes in geometry dramatically affect performance.
Advanced considerations include:
- Long-pole stems (shorter total travel, sharper bottom-out sound)
- Rounded tactile legs (smoother bump)
- Sharp tactile legs (more aggressive feedback)
- Stem material affecting friction and acoustics
This is where enthusiast keyboard switches truly differentiate themselves, as the stem can decide the ‘feel’ - if it’s linear or a tactile feel and where that tactility is.
Our AEBoard switches are tailored to how we like our switches. The Naevies are a long pole and medium tactile bump, creating that deeper clack when typing and having that nice feedback.
Blaecks and Raeds are our linear ranges, the blaecks is a more standard linear feel comparable to the MX red/black switch with its normal pole length. The raeds are a more tailored linear feel, with the longer pole adding that deeper clack.
3. Spring
The spring defines actuation force and return speed.
- Standard springs: consistent resistance
- Progressive springs: increasing resistance as pressed
- Long springs: faster return, snappier feel
For competitive gaming, return speed can matter as much as actuation weight.
Our AEBoard switches use double springs allowing a Faster, snappier return which accentuates the tactility and consistency force curves reducing spring wobble or crunching.
4. Contact Mechanism
Traditional mechanical switches use metal contact leaves. However, premium alternatives include:
- Electro-capacitive (EC) switches – capacitive sensing without physical contact
- Hall-effect (HE) switches – magnetic sensing with adjustable actuation
These technologies are becoming increasingly popular in the last year or so in high-end Australian custom builds, and we have our own EC and HE switches in collaboration with TecSee – the Naevies EC and Raeds HE.
The Three Main Types - Linear vs Tactile vs Clicky Switches
When discussing the types of mechanical keyboard switches, the three core categories remain essential.
1. Linear Switches
Linear switches provide uninterrupted, smooth keystrokes from top to bottom.
Characteristics:
- No tactile bump
- No click mechanism
- Consistent force curve
- Clean acoustic profile
Linear switches are widely considered the best mechanical switches for gaming. Their smooth travel enables rapid double-tapping, fast strafing and consistent movement.
High-end linear switches often feature:
- Factory lubrication
- Long-pole stems
- Tight housings for reduced wobble
For serious gaming builds, premium linear switches are often the starting point.
Try our Blaecks or Raeds for that classic linear experience.
2. Tactile Switches
Tactile switches introduce a noticeable bump at the actuation point.
Characteristics:
- Physical confirmation of actuation
- Reduced bottoming-out fatigue
- Controlled input
For developers, writers and analysts, tactile switches are often the best switches for typing. The bump encourages lighter keystrokes and improves rhythm over long sessions.
Advanced tactile switches vary significantly:
- Light tactility (subtle bump)
- Medium tactility (balanced feedback)
- Heavy tactility (pronounced resistance)
Not all tactile switches feel the same — geometry matters.
Try our Naevies for our refined custom tactile experience.
3. Clicky Switches
Clicky switches add an audible click to tactile feedback.
They provide:
- Strong acoustic confirmation
- Classic typewriter-style sound
- Clear actuation indication
However, in professional or shared environments, clicky switches are less practical due to noise levels.
How to Choose the Right Mechanical Keyboard Switch
A practical decision framework:
1. Identify Your Primary Use
Gaming → Linear eg. Blaecks
Typing-heavy work → Medium tactile. Eg Naevies
Mixed use → Balanced tactile or smooth linear eg. Raeds, Naevies
2. Evaluate Environment
Office setting → Avoid clicky
Home studio → Consider acoustic profile
3. Assess Fatigue & Force Preference
If you bottom out heavily, a tactile switch may improve control.
If you value speed, lighter linear options may feel more responsive.
4. Consider Future Flexibility
Hot-swappable keyboards allow experimentation. This is ideal for those exploring custom keyboard switches in Australia.
The Long-Term Value of Premium Switches
Premium mechanical switches are engineered for longevity and consistency, often rated for 50–100+ million keystrokes. They offer reduced stem wobble, smoother travel, stable actuation curves and more refined acoustic characteristics. Over years of daily use, that precision becomes increasingly noticeable. Where cheaper switches can feel inconsistent and unstable, premium switches deliver a controlled, engineered experience built for long-term performance.

Frequently Asked Questions
1. What is the difference between linear and tactile switches?
Linear switches move smoothly without feedback, while tactile switches provide a bump at the actuation point. Tactile switches offer more typing confirmation; linear switches prioritise speed.
2. Which mechanical keyboard switch is best for gaming?
Linear switches with lighter actuation are commonly preferred. Hall-effect switches are increasingly popular due to adjustable actuation and rapid trigger capability.
3. Are mechanical keyboard switches replaceable?
Yes. Many modern keyboards are hot-swappable, allowing switches to be removed and replaced without soldering.
4. How long do mechanical switches last?
Premium mechanical switches are typically rated between 50 and 100 million keystrokes, significantly outlasting membrane keyboards.
5. What switch should beginners choose?
A medium-weight tactile switch is often a safe starting point, offering balanced performance for both typing and general use.
