Optical vs Mechanical Switches ⚖️ | Evetech

When buying a new gaming keyboard in South Africa, you’ll face a crucial choice: stick with traditional mechanical switches or leap to newer, faster optical switches? For years, mechanical keys were the undisputed kings for gamers and typists. But now, optical technology promises a speed and durability advantage that’s hard to ignore. Which one is right for your playstyle, your budget, and your fingers? Let’s break down the real-world differences. ⌨️

Head-to-Head: Optical vs. Mechanical Switches

At their core, these two technologies do the same thing, but how they do it changes everything, from raw speed to the feeling you get with every single keystroke.

Feature Optical Switches Mechanical Switches
Actuation Method A beam of infrared light is broken by the keypress. No physical contact. Two metal contacts touch to complete a circuit.
Speed & Latency Faster. Light-speed actuation with zero debounce delay. Very fast, but has a tiny (imperceptible to most) debounce delay.
Durability Extremely high (often rated for 100 million+ keystrokes). No metal parts to wear out. Very high (typically 50-80 million keystrokes).
Feel & Variety Smooth and consistent. Fewer options, can feel less distinct to some. Massive variety: clicky, tactile, linear. The "gold standard" for typing feel.
Best For Competitive gamers seeking the absolute fastest input possible. Typists and gamers who prioritise a satisfying feel and customisation.

TIP FOR YOU

The Adjustable Actuation Pro-Tweak

A huge advantage of some modern optical keyboards is adjustable actuation. In the software, you can set the actuation point really high (e.g., 1.0mm) for ultra-responsive gaming, then lower it (e.g., 1.8mm) when you need to type an essay to avoid accidental keystrokes.

The Verdict: Who Should Buy What?

The right switch for you comes down to a simple question: what do you value more, pure speed or satisfying feel? Let's map this to a couple of typical South African gamers.

Zanele, the Esports Competitor

Zanele plays fast-paced shooters like Valorant and Apex Legends at a high level. For her, every millisecond counts. The winner is clearly Optical Switches. Their debounce-free, light-speed actuation gives her a small but tangible edge in reaction time. When she’s doing rapid counter-strafing, she knows her inputs are registering as fast as physically possible. The superior durability is just a bonus for her intense, daily training sessions. 🚀

David, the All-Round Gamer & Typist

David loves gaming, from Helldivers 2 with his mates to epic single-player RPGs. He also uses his PC for varsity assignments and typing in Discord. For him, the rich, tactile feel of traditional Mechanical Switches is unbeatable. He loves the satisfying "thock" of his tactile keys and the huge variety available, allowing him to find the perfect switch for that ideal typing experience. For David, the enjoyment of using the keyboard every day outweighs the fractional speed advantage of opticals. ✨

There’s no wrong answer here, only what’s right for your hands and your games.

Optical switches typically hit 100M+ keystrokes vs 50M for mechanical. No metal contact erosion makes optical more durable.

Yes. Optical switches offer sub-0.001ms actuation with zero debounce lag, critical for competitive gaming scenarios.

Mechanical switches use gold-plated contacts that physically connect when pressed, wearing over time from friction.

Optical switches resist dust buildup thanks to sealed optical sensors vs mechanical switches' exposed contact points.

Analog optical switches detect pressure intensity through light modulation, enabling gradient actuation for creative workflows.

Mechanical switches provide superior tactile bump profiles with Cherry MX Blue/Clicky variants being audiophiles' favorites.

Advanced optical switches use beam-break tech that instantly resets, eliminating mechanical bounce issues in budget switches.

Optical switches reduce stem scraping noise but still create housing vibrations – sound differences depend on switch design.
