Comprehensive Guide to Keyboards

1. Core Definition

A “Keyboard” is a primary input device used to enter text, numbers, commands, and other data into computers, laptops, smartphones, gaming consoles, or other electronic devices. It features a layout of keys (alphabetic, numeric, function, and special keys) that translate physical presses into digital signals. Keyboards vary by connectivity (wired/wireless), switch type (mechanical/membrane), design (ergonomic/compact), and use case (productivity/gaming/content creation), serving as an essential tool for work, communication, and entertainment. Key specifications include switch type, key travel, actuation force, connectivity, and durability.

3. Common Types by Switch Type, Connectivity, and Use Case

Category	Type Name	English Expression	Key Features & Details
By Switch Type	Mechanical Keyboard	Mechanical Keyboard	Uses individual mechanical switches (e.g., Cherry MX, Gateron, Kailh) under each key. Offers tactile feedback, audible clicks (optional), fast actuation, and durability (50-100 million keystrokes). Popular for gaming, typing, and professionals. Subtypes:- Tactile (non-clicky): Tactile bump without noise (e.g., Cherry MX Brown).- Clicky: Tactile bump + audible click (e.g., Cherry MX Blue).- Linear (smooth): No bump/click, smooth keystroke (e.g., Cherry MX Red).
	Membrane Keyboard	Membrane Keyboard	Uses a rubber membrane layer to register key presses. Slim, affordable, quiet, and lightweight. Less durable (10-20 million keystrokes) than mechanical keyboards. Common in office setups, laptops, and budget devices.
	Scissor Switch Keyboard	Scissor Switch Keyboard	Hybrid design (between membrane and mechanical); uses scissor-like hinges for stable key presses. Slim, quiet, and responsive. Found in modern laptops (e.g., MacBook, Dell XPS) and compact wireless keyboards.
	Optical Keyboard	Optical Keyboard	Uses light sensors (instead of physical contacts) to detect key presses. Fast actuation (0.1ms), durable (100+ million keystrokes), and resistant to dust/water. Popular for gaming and heavy use.
	Hall Effect Keyboard	Hall Effect Keyboard	Advanced optical-mechanical hybrid; uses magnetic fields and Hall effect sensors. Ultra-fast, durable, and customizable (adjustable actuation point). Premium option for gaming and professionals.
By Connectivity	Wired Keyboard	Wired Keyboard	Connects via USB-A, USB-C, or PS/2 (outdated). Zero latency, no battery required, and stable connectivity. Ideal for gaming, programming, and critical work.
	Wireless Keyboard	Wireless Keyboard	Connects via Bluetooth (3.0+/5.0+), 2.4GHz USB dongle, or Wi-Fi. Cable-free, portable, and clutter-free. Battery life: 1-12 months (rechargeable or replaceable). Suitable for home/office use, laptops, and smart TVs.
	Bluetooth Keyboard	Bluetooth Keyboard	Universal wireless connectivity (works with phones, tablets, laptops, and smart devices). No dongle required; supports multi-device pairing (switch between 2+ devices).
	2.4GHz Wireless Keyboard	2.4GHz Wireless Keyboard	Uses a dedicated USB dongle for low latency (better than Bluetooth for gaming). Plug-and-play; no pairing needed.
By Use Case & Design	Gaming Keyboard	Gaming Keyboard	Optimized for gaming: RGB backlighting, macro keys (programmable), anti-ghosting (104+ keys), high polling rate (1000Hz), and mechanical/optical switches. Some include wrist rests, media controls, or detachable cables.
	Productivity/Office Keyboard	Office Keyboard	Focus on comfort and efficiency: quiet switches (membrane/scissor), ergonomic design, hotkeys (for shortcuts), and compatibility with office software (Excel, Word). May include numeric keypads and wrist rests.
	Ergonomic Keyboard	Ergonomic Keyboard	Designed to reduce wrist/neck strain: split keyset (separated left/right), curved layout, tenting (angled keys), and palm rests. Ideal for users with repetitive strain injury (RSI) or long typing sessions.
	Compact Keyboard	Compact Keyboard	Reduced size (no numeric keypad, smaller function keys):- Tenkeyless (TKL): 87 keys (no numpad).- 60%: 61 keys (no numpad/function keys/arrow keys).- 75%: 70-75 keys (balances compactness and functionality).Portable and space-saving for small desks or travel.
	Mechanical Gaming Keyboard	Mechanical Gaming Keyboard	Combines mechanical switches with gaming features (RGB, macros, anti-ghosting). Popular among competitive gamers for tactile feedback and fast response.
	Wireless Travel Keyboard	Travel Keyboard	Ultra-compact, lightweight (≤300g), and foldable/rollable. USB-C rechargeable; compatible with laptops/phones. Ideal for travel or remote work.
	Backlit Keyboard	Backlit Keyboard	Features LED backlighting (single-color or RGB) for low-light environments. Adjustable brightness; some offer per-key RGB customization.
	Numeric Keypad Keyboard	Numeric Keypad Keyboard	Dedicated 17-key numeric keypad for data entry (accounting, spreadsheets). Standalone or integrated into full-size keyboards.
