How Each Switch Type Works

Before comparing performance, it helps to understand the fundamental difference in how each switch registers a keypress. They all do the same job but through completely different mechanisms.

Mechanical Switches

Traditional mechanical switches use a physical metal contact point. When you press a key down far enough, two metal leaves touch, completing an electrical circuit and registering the keypress. This is why they have a characteristic click or tactile bump: that is the physical moment of actuation happening. The spring underneath resets the key when you release.

The debounce algorithm is a small software delay (typically 5 to 10ms) required because metal contacts bounce microscopically on contact, which would otherwise register multiple keypresses. This matters a lot when comparing speed to optical switches.

Optical Switches

Optical switches replace the metal contacts with an infrared light beam and a sensor. When you press the key, the stem physically blocks the light beam, triggering the registration. Because there is no physical contact happening, there is no bouncing and therefore no debounce delay needed. This is the true source of their speed advantage.

They are also more durable in theory since there are no metal contacts to corrode or wear down. Most optical switches are rated for 100 million keystrokes versus 50 to 100 million for mechanical depending on the brand.

Magnetic (Hall Effect) Switches

This is where 2026 gets interesting. Hall Effect switches use magnets and a magnetic field sensor to detect key position. Instead of a fixed actuation point, they detect the exact position of the key at any point in its travel. This enables analog mode, where the key behaves like a joystick axis, and crucially, adjustable actuation points.

You can set actuation at 0.1mm for hair-trigger competitive gaming, or 3.8mm for a deliberate, heavy typing feel. All via software on the same switch. Keyboards like the Wooting 60HE and the Epomaker HE80 run Hall Effect switches. They combine the contactless speed of optical with far greater feel customisability than either optical or traditional mechanical.

Full Head-to-Head Comparison

Here is how all three switch types stack up across every dimension that matters to keyboard enthusiasts and gamers alike.

Category	Optical	Mechanical	Magnetic (HE)
Speed	Very fast (no debounce) WIN	Slower (debounce delay)	Very fast + adjustable WIN
Feel	Hollow, less satisfying	Rich, tactile, thocky WIN	Good, improving rapidly
Sound	Loud, plasticky	Deep, customisable WIN	Similar to mechanical
Durability	100M keystrokes WIN	50 to 100M keystrokes	100M+ (no contacts) WIN
Price	Mid-to-high	Budget to premium WIN	Premium only
Variety	Limited (few dozen)	Enormous (hundreds) WIN	Growing but limited
Moddability	Very limited	Excellent (lube, film, swap) WIN	Moderate
Adjustable Actuation	No	No	Yes, 0.1mm to 4.0mm WIN
Hot-swap Compatible	Requires optical PCB	Universal (most boards) WIN	Requires HE PCB
Best For	Competitive FPS	Typing, modding, value	All-around in 2026

Speed: The Real Data

Speed is the most cited reason to choose optical over mechanical. But the reality is more nuanced than most articles admit. Real-world reaction time testing across four popular switch types produced this result:

Switch	Type	Actuation	Avg Reaction Time
Razer Optical Purple	Optical	1.5mm	0.2304s
Cherry MX Red	Mechanical	2.0mm	0.2466s
Cherry MX Speed Silver	Mechanical	1.2mm	0.2468s
Gateron Optical Black	Optical	2.0mm	0.2624s

The key insight here: not all optical switches are fast. The Gateron Optical was actually slower than mechanical in testing. Only Razer’s implementation showed a meaningful 30ms advantage, because it genuinely eliminates the debounce delay. Most budget optical switches still apply a software debounce, which closes the gap considerably.

Sound and Feel: Where Mechanical Wins

This is where traditional mechanical switches are unmatched, and where the keyboard enthusiast community lives. Optical switches produce a sound typically described as hollow and plasticky. There is a lack of weight to the bottom-out that fans of deep, thocky keyboards find unsatisfying.

Mechanical switches, by contrast, are endlessly moddable for sound. You can lube the switch stem for a smoother, deeper sound, add switch films to tighten housing rattle, swap in different springs for different weight, and install foam under the PCB to absorb high frequencies. The result is the kind of deep, full thock that optical simply cannot replicate.

Hall Effect switches sit between the two. They share a similar physical structure to mechanical (spring, stem, housing), so they can be modded and lubed, and they produce a comparable sound. Some enthusiasts note HE switches feel slightly lighter at the same actuation weight, but this is improving with each new generation.
