Introduction to Capacitive Keyboards: Why Are They Called the 'Ultimate Keyboard'?

When you press the keys with very little force, it feels as if you haven't pressed them at all – that's the charm of electrostatic capacitive keyboards. There's no need to firmly press down like with mechanical switches; some models can register input with just 25g of pressure.

This reduces strain on your fingers, makes typing quieter (about 15dB quieter than many clicky types), and provides a smooth keystroke feel, allowing for comfortable work even over long periods.

In this guide, we'll explain what makes electrostatic capacitive switches unique, how to test the keystroke feel yourself, and how to choose the right model for you using the '4P Purchase Framework (Price, Profile, Programmability, Portability)'.

If you type for long hours, this might be the ideal keyboard for you.

1. What is an Electrostatic Capacitive Keyboard?

Electrostatic capacitive keyboards adopt a 'contactless' switch structure. Instead of physical metal contacts, pressing a key changes the electric field between two conductive layers on the circuit board, which is then read by a sensor to recognize input.

Main Structure:

• Electrostatic Field Plate: Located under each key, it detects changes in the electric field.

• Keycap Slider: Moves straight up and down without touching metal contacts.

• Sensor-equipped PCB: Instantly detects minute changes in the electric field when a key is pressed.

Since there are no physical contacts, wear and tear is minimal, and the keystroke feel remains unchanged from start to finish, boasting durability of over 50 million keystrokes.

Comparison Table: Electrostatic Capacitive vs Mechanical vs Membrane

Differences in Typing Feel:

• Keystroke Feel: Light and smooth with fast spring return

• Quietness: Ideal for office use or late-night work

• Durability: Long-lasting due to non-wearing structure

Common Misconceptions

• Isn't it just an expensive membrane?
  　→ Membrane uses rubber dome structure, while electrostatic capacitive has different sensing methods allowing for various actuation points.

• Doesn't it only respond if you bottom out the keys?
  　→ It reacts at the midpoint, making floating typing efficient.

• Aren't all electrostatic capacitive keyboards the same?
  　→ Keystroke, spring strength, and key shape vary significantly.

Checklist Before Purchasing

1. Actuation Force Comparison
   Compare pressing 25g and 45g switches to experience the lightness.

2. Sound Level Measurement
   Type 100 words on each keyboard using a smartphone app; electrostatic capacitive is extremely quiet at about 40dB.

3. Typing Fatigue Test
   After a 60WPM test, switching to another keyboard reveals less finger fatigue with the electrostatic capacitive.

4. Key Return Comparison
   Observe key return using smartphone slow-motion; excellent response speed advantageous for gaming rapid presses.

Why Choose NIZ Capacitive Keyboards?

• ✅ True Capacitive Sensing: Detects key inputs with 0.1mm resolution without metal contacts.

• ✅ Patented Silent Switches: Built-in dampers reduce noise by 15dB compared to competing products.

• ✅ Modular Design: Keys are hot-swappable, allowing for spring and custom keycap replacements.

• ✅ Longevity and Support: Comes with a 5-year warranty on switch performance. Spare parts are also available.

Maintenance and Care

• Dust and Foreign Object Removal: Clean by blowing compressed air between the keycaps every month.

• Surface cleaningWipe with 70% isopropyl alcohol and ensure the PCB does not get wet.

• Keycap replacementUse a keycap puller to remove them. Keep the capacitive plate dry.

• Firmware updateDownload the NIZ Utility to readjust actuation points or backlight effects.

Frequently Asked Questions (FAQ)

• Do I need to press all keys down to the bottom?
  　 → No, since capacitive switches respond at the actuation point (typically 1.2mm–3.5mm), there's no need to press the keys fully. You can press lightly based on your preference.

• Is gaming possible with 1ms low latency?
  　 → Yes. Capacitive detection offers superior response speed compared to mechanical, accurately reacting even during fast actions or macro operations.

• Is it worth the higher price compared to membrane keyboards?
  　 → For those typing over 40 hours a week or prioritizing quietness, it offers comfort and durability, making it a worthwhile investment.

• What layouts are available for NIZ keyboards?
  　 → We offer layouts ranging from 60% size to full-size, supporting ISO/ANSI configurations, as well as ergonomic sloped keycap sets.
