Gaming mice often tout flashy designs or high DPI, but the true star is the microswitch—the tiny component beneath each button that determines precision, speed, and lifespan. A quality microswitch can mean the difference between a decisive headshot or a frustrating double-click failure, whether you’re gaming or working.

How Microswitches Work

At their core, microswitches are tiny electro-mechanical (or optical) devices that convert physical button presses into digital signals your computer understands. Let’s break down the two main types and how they function:

1. Mechanical Microswitches

The most common design, mechanical switches use a metal reed (contact blade) and a spring-loaded lever. 
When you click the mouse button:
The lever presses down on the reed, causing two metal contacts to touch and complete an electrical circuit (this is the "actuation").
The actuation force (measured in grams) determines how hard you need to press—light switches (30-50g) feel snappy for rapid clicks, while heavy ones (60-80g) offer tactile resistance.
Lifespan varies drastically: Budget switches (e.g., generic Huano) might fail after 5-10 million clicks due to contact oxidation or debris buildup, while premium options like OMRON, found in many of the best gaming mouse models, last 50 million clicks by using gold-plated contacts to resist corrosion.

2. Optical Microswitches

A newer, premium alternative, optical switches replace physical contacts with infrared beams:
When you click the mouse button:
A plastic actuator breaks the beam between two sensors, triggering the click without any moving metal parts.
Advantages? No physical wear, near-zero chance of double-clicking, and faster response times .
Drawback? They lack the tactile "snap" some gamers love, though modern designs like Logitech’s Hybrid Optical-Mechanical switches mimic that feel while adding durability.

Top Microswitch Brands & Models

1. OMRON

OMRON dominates the microswitch market with precision-engineered models trusted by gamers and OEMs alike. Key offerings include:
D2FC-F-K (50M) (Chinese): A 60–80gf switch with a 50 million click lifespan, praised for its balanced tactility and resistance to oxidation. Found in flagship mice like the Logitech G Pro X Superlight 2.
D2FC-F-7N Series: The iconic "white dot" switches, available in 10M, 20M, and 50M variants. The 20M version (75gf) offers a slightly softer feel than the original, while the 50M model (60gf) prioritizes longevity.
D2FP-FN2 model: Omron's optical microswitches, utilize contactless optical sensors instead of mechanical metal contacts. This design eliminates oxidation issues and mechanical wear, offering up to 100 million clicks of lifespan .Coming soon to VGN’s lineup: The Dragonfly Y2 series will be the first mouse in our catalog to feature OMRON’s D2FP-FN2 optical switches, engineered for competitive gamers who demand lag-free precision. Ideal for FPS, MMO, and RTS genres, the Dragonfly Y2 combines this industry-leading tech with ergonomic design.
Widely used in premium gaming computer mice， they balance speed and reliability for FPS/MMO genres .
Strengths: Unmatched consistency, premium materials (gold/silver contacts), and industry-standard reliability.

2. TTC Gold

TTC’s Gold series redefines durability with innovative 防尘墙 (dustproof wall) technology:
TTC Dustproof Gold Microswitch: A 0.68N switch rated for 30–60 million clicks, featuring a 5-layer dustproof design that channels debris into a reservoir, preventing internal jamming. Its semi-transparent housing allows visual inspection of the gold-plated contacts.
TTC Gold Hybrid: Combines optical actuation with a mechanical spring for 100+ million click lifespan and tactile feedback. 
Strengths: Extreme dust resistance, hybrid designs for both speed and feel, and IP54-rated protection.

3. Kailh

Kailh balances performance and affordability with models like:
GM8.0 Black Mamba: An 90 million click switch with 0.65N actuation, offering a smooth, linear feel. Its reinforced spring minimizes pre-travel, making it the preferred choice for esports mice like the VGN Dragonfly F1 Pro and VGN Dragonfly F1 Pro Max. hese mice leverage the Black Mamba’s durability to deliver consistent, fatigue-free clicks.
GM4.0 Red: A 60 million click switch with 20gf actuation (0.2N), designed for ultra-light presses in MMO/RTS games.
Red Dot GM: A 60 million click switch with 24K gold-plated contacts and grid-patterned contact surfaces, reducing wear during high-frequency use.
Strengths: Cost-effective longevity, diverse actuation forces, and optical variants (e.g., Kailh’s light-magnetic switches) that eliminate contact wear.

4.HUANO

HUANO is a Chinese brand founded in 1987, specializing in microswitches, encoders, and other components. It supplies microswitches to renowned brands like HP, Lenovo, ASUS, and MSI, with its products widely used in gaming mice due to their cost-effectiveness and stable performance. 
HUANO 50M:
Specs: 50 million click lifespan, actuation force of 60–80gf, featuring a crisp tactile feedback and fast response.
Applications: Used in gaming mice like the Thunderobot ML7 and Rapoo V30W , suitable for FPS and RTS games requiring rapid clicks. Users praise its durability and balanced feel, comparable to OMRON’s D2FC-F-K (50M) .
HUANO Pink Dot Microswitches
HUANO's Pink Dot series is a premium line of microswitches designed for gaming mice and office peripherals, known for high durability and lightweight actuation. 
It powers the Dragonfly F1 MOBA, optimized for rapid combo execution in games like League of Legends. Its lightweight design reduces finger strain during extended play, while gold alloy contacts ensure 80+ million-click durability—perfect for MOBA players who spam abilities.
Gold Alloy Contacts: Enhance oxidation resistance and lifespan.
Blue Shell Pink Dot (BSPD): 80 million clicks, ideal for competitive gaming.
Transparent Blue Shell Pink Dot (TB SPD): Lighter actuation force (version 2) for faster responses.
BSPD: ~70gf (0.74N), balanced for FPS/RTS games.
Ice Berry Pink Dot: ~55gf, optimized for quiet office use.
HUANO switches offer competitive pricing without compromising on basic performance, making them ideal for mid-range gaming computer mice. A wide range of actuation forces and silent/dustproof variants cater to different user needs, from office work to computer gaming.
