Click Switches

Introduction

• Switch = the tiny part under left + right click that tells the MCU 'a click happened'. TOP 6 part (#5).
• You click THOUSANDS of times a day, so feel, speed and reliability all matter.
• 2026 = the year MAGNETIC switches arrived in mice. One of the biggest changes to check before you buy.

~ like: a light switch you press thousands of times - if it flickers, it's useless.

1. The switch family tree

metal contact -> light beam -> magnetic: the three switch generations

~ like: phones: keypad phones (mechanical) -> touchscreens (optical) -> face unlock (magnetic = no touching at all).

2. Mechanical switch (the classic)

press -> leaf snaps -> metal contacts touch -> CLICK

Press -> leaf snaps -> metal contacts touch -> CLICK.

Problem: metal BOUNCES for a few ms after touching, like a ruler slapped on a desk vibrates.

Bounce vs clean signal:

the metal contact bounces for a few ms; light and magnetic sensing don't

• Debounce: de + bounce = removing the bounce. A short wait (often ~5-15ms) where extra signals are ignored so 1 press = 1 click.
• Double-click problem: contacts wear out -> bounce gets worse -> one press becomes TWO clicks.e.g. Chinese-made Omrons in older Logitech G Pro and G502 got famous for double-clicking.~ like: an old TV remote button that sometimes changes 2 channels with one press.

3. SPDT (2 contacts)

the mouse always knows which contact was touched last

• How it helps: the mouse knows which contact was touched LAST (SR-Latch logic), so it can ignore bounce without a long debounce wait.e.g. G-Wolves Lycan / VUK: Huano SPDT + SR-Latch - G-Wolves claims ~30ms faster.e.g. Ninjutso Sora V3: SPDT HyperSwitch, marketed as won't double-click.e.g. Endgame Gear Kailh GX: top and bottom contacts, 'GX Speed Mode' or 'GX Safe Mode'.

~ like: a railway track switch - one moving rail, two tracks. The station always knows which track the train is on.

4. Optical switch

break the beam, register the click - nothing touches

~ like: the beam at a lift door - break the beam and it reacts instantly, nothing touches.

• Pros: no debounce, no bounce double-clicks, long life (often rated up to ~100M clicks).
• Cons: early ones felt mushy - modern ones mostly closed the gap.e.g. Razer made in-house optical switches after the double-click drama - first in the Razer Viper. Gen-1 felt mushy, Gen-3 in the Basilisk V3 Pro (claims 90M clicks), now Gen-4 in the Viper V4 Pro.

Razer's own optical switches, generation by generation:

1. Gen-4 - now, in the Viper V4 Pro
2. Gen-3 - in the Basilisk V3 Pro, claims 90M clicks
3. Gen-1 - first Razer Viper, felt mushy

• Hybrid: optical detection + a real mechanical leaf for the crisp click.e.g. Logitech LIGHTFORCE (LIGHT = optical, FORCE = mechanical feel) - first in the G502 X, also the G309.~ like: an electric car with a real engine sound - electric speed, familiar feel.

5. MAGNETIC switches (the 2026 wave)

Magnetic tech already fixed drifting controller sticks (Hall effect) and made keyboards faster (rapid trigger). In 2026 it reached mice.

~ like: a car parking sensor - it knows how close you are WITHOUT touching.

The 3 magnetic types:

three ways mice now sense a click without metal touching

• Hall effect (HE): named after scientist Edwin Hall (1879): a magnetic field creates a tiny measurable voltage. A magnet moves with the button, the sensor measures how close it is.
• TMR: Tunnel MagnetoResistance: electrons 'tunnel' through an ultra-thin wall between 2 magnetic layers; how easily they pass changes with the magnet. Commonly described as more sensitive and lower power than Hall.~ like: Hall = normal thermometer, TMR = a more sensitive digital one.~ like: Hall effect - feeling a fire's heat grow as you walk closer, without touching it.
• Inductive: from electromagnetic induction: a coil's field changes as a metal part gets closer -> measures press depth.~ like: the airport metal detector, or an induction cooktop that knows when a steel pan is placed on it.~ like: haptic click = your phone's vibration keyboard - no real button moves, but your finger FEELS a tap.

What magnetic unlocks:

button depth, and how rapid trigger resets before a full release

• Adjustable actuation: YOU choose how deep the press must go to count.~ like: a phone camera - half-press to focus, full press to shoot - you choose where the 'shot' happens.
• Rapid Trigger: the button 'rapidly' resets - a new click registers as soon as your finger starts lifting.~ like: a normal door must close fully before reopening. Rapid trigger lets you reopen it the moment it starts closing.
• No wear double-clicks: no metal contact = no bounce = no contact-wear double-clicking.

Magnetic mice (real examples):

• Logitech G Pro X2 Superstrike: released 10 February 2026 - the one that started the wave. HITS = Haptic Inductive Trigger System: tiny haptic motors + inductive sensors replace the microswitch. Actuation adjustable in 10 levels. Silent buttons.Independent tests show: 8-9% faster in pure reaction tests, ~20% more clicks/sec with rapid trigger when butterfly/jitter clicking.(caveat: the 30ms advantage needs the LOWEST actuation setting - you'll need to unlearn resting tension on your fingers)(turned off, the buttons feel like almost nothing - 'like a broken mouse')India price: ₹23,995.
• Finalmouse Starlight X: 38g, TMR sensing for rapid trigger + adjustable actuation, but the click feel itself is not adjustable. Custom F1 sensor (with PixArt) + Nordic nRF54LM20.
• Keychron MagOptic: MagOptic = Magnetic + Optical. Real mechanical leaf click, detection by optical OR magnetic mode. Fixes the 'no real click' complaint about the Superstrike.
• G-Wolves HTS Plus Pro: TMR magnetic main switches.
• Coming next: RAWM Leviathan V4 GT (hybrid optical-magnetic), an Everglide magnetic mouse, a leaked Logitech X3 Superstrike (+50% battery reported).

Market story

One worry: the market could split into mechanical vs optical vs magnetic mice.

Hybrid switches (like the Keychron MagOptic) avoid that - one switch, choose your mode.

The real question before you buy: 'Real click or haptic click - which do YOU want?'

6. Who makes switches?

• Omron (Japan): the classic, historically in a big share of mice. D2FC-F-7N (20M) + D2FC-F-K (50M, 'Blue Dot' - known for double-clicking in some Logitech and Razer mice). Japanese vs Chinese-made can feel and last differently.
• Kailh (China): many types: GM 8.0, GX (with Endgame Gear), GM Red Dot (60M, 24K gold-plated contacts), optical and magnetic variants.
• Huano (China, since 1987): firm, tactile click. Supplies HP, Lenovo, ASUS, MSI. Blue Shell Pink Dot, Huano 50M, Huano SPDT (G-Wolves).
• TTC (China): modder favourite. TTC Gold (light), TTC Silver (~52gf).
• Razer (in-house): own optical switches, not sold separately.
• Logitech (in-house): LIGHTFORCE hybrid + HITS inductive.
• Keychron: MagOptic hybrid optical + Hall (Keychron G6 HE).
• Others: Zippy, Honeywell, ZF/Cherry appear in switch comparison sheets.

~ like: tyre brands: MRF, Apollo, CEAT all make tyres - same job, different feel, grip and life.

!! Community claim: Chinese Omron '-K' switches fare better than older ones but can still fail after about a year of heavy use.

7. The big comparison

• Mechanical: real click - yes · debounce - yes · double-click risk - higher · adjustable actuation - no · rapid trigger - no
• SPDT: real click - yes · debounce - very short · double-click risk - low · adjustable actuation - no · rapid trigger - no
• Optical: real click - yes* · debounce - no · double-click risk - very low · adjustable actuation - no · rapid trigger - no
• Hybrid: real click - yes · debounce - no · double-click risk - very low · adjustable actuation - no · rapid trigger - no
• Magnetic: real click - leaf or haptic · debounce - no · double-click risk - very low · adjustable actuation - YES · rapid trigger - YES

(* early optical felt mushier. 'Hybrid' = LIGHTFORCE-style. Magnetic features depend on the mouse.)

~ like: choosing a phone - every type makes calls - the difference is battery life, speed and features.

8. Click latency - keep it honest

switch speed barely matters next to your own reaction time

~ like: in cricket, a faster bat helps - but the batter still needs ~200ms+ to react to the ball.

-> switch speed helps, but your own reaction time is MUCH bigger. Keep this in mind before you buy - a switch's raw speed matters less than the marketing suggests.

9. It's not just the switch

• Button tension system: how the shell button presses on the switch. This is why the SAME switch feels different in 2 mice.e.g. Logitech G502 HERO: metal spring tensioning + metal pivot hinges. Ninjutso HyperClick: tension system aimed at removing pre-travel.~ like: two doors with the same lock but different hinges - one opens smooth, one feels stiff.
• Silent switches: quieter clicks for office / late-night use - softer feel.~ like: typing in a library or late at night while family sleeps.

10. Which switch for which player?

Butterfly / drag click → low-debounce mechanical Kailh GM 8.0, Huano Blue Shell Pink Dot

MOBA / RTS → light switches Japanese Omron, TTC Gold

Tactical shooters → firmer click Huano - harder to misclick

Semi-auto spam → magnetic + rapid trigger Superstrike-style

11. 'My mouse double-clicks - what now?'

1. Test: run an online double-click test.
2. Debounce: raise it in software.
3. Warranty: claim if covered.
4. Replace: hot-swap or solder.

Next mouse? Consider optical, hybrid, SPDT or magnetic switches.

~ like: a worn shoe sole - you can re-sole it (replace switch) or buy shoes that don't wear that way.

12. Switch Dictionary (why it's called that)

• Microswitch: a very small switch - what sits under every mouse button.
• Leaf spring / 'shrapnel': the thin metal strip that snaps. Chinese spec sheets often translate it as 'shrapnel'.
• SPDT: Single Pole Double Throw - one moving part (pole) that can touch two positions (throws). Like a railway track switch.
• SR-Latch: Set-Reset latch - logic that remembers which contact was touched last.
• Optical: from 'optics' = light. Infrared beam gets blocked.
• LIGHTFORCE: Light (optical detection) + Force (mechanical feel).
• Hall effect: named after Edwin Hall, 1879.
• TMR: Tunnel MagnetoResistance.
• HITS: Haptic Inductive Trigger System (Logitech).
• Haptic: from the Greek word for TOUCH - the tiny vibration that fakes a click.
• MagOptic: Magnetic + Optical (Keychron).
• Actuation point: from 'actuate' = put into action. The depth where the click counts.
• Rapid Trigger: the trigger resets rapidly.
• Hysteresis: the gap between the press point and release point. Rapid trigger removes the fixed gap.
• Debounce: de + bounce = removing the bounce.
• 20M / 50M / 100M: rated lifespan in MILLIONS of clicks - a lab rating, not a promise.
• gf: gram-force - pressing force. ~52gf = like 52 grams pushing down.
• Blue / Pink / Red Dot: coloured dot marking the switch variant.
• Gold-plated contacts: gold doesn't rust/oxidise, so contacts stay clean longer.
• Hot-swap: change switches without soldering - like replacing a bulb, not rewiring the lamp.
• Pre / post-travel: button movement before / after the click.

13. What to check before you buy

1. run an online double-click test
2. check the debounce setting in software (lower = faster, riskier on mechanical)
3. check pre-travel and post-travel on BOTH buttons
4. check for side-to-side button wobble
5. ask the seller for the switch type and brand (or check the spec sheet)
6. MAGNETIC: how many actuation levels? does rapid trigger feel natural?
7. MAGNETIC: haptic strength and battery cost - does it feel like a real click?
8. sound: loud / quiet / silent

Remember!!

Mechanical = metal + bounce + debounce. SPDT = 2 contacts, smarter. Optical = light beam. Hybrid = optical + real click.

Magnetic (Hall / TMR / inductive) = adjustable actuation + rapid trigger + no contact wear.

Same switch feels different in 2 mice (button tension). Switch speed is much smaller than human reaction time.

The Superstrike started the magnetic wave in 2026 - real click vs haptic click is the new debate.
