What This Tool Measures
This tool is a visual simulator, not a hardware calibration tool, as browsers only capture key down and key up events, not real analog depth. It uses switch specifications to show actuation, reset, and bottom-out behavior, while Keyboard Hold Simulation and Manual Depth Scrub help you explore the travel path and understand real feel.
How to Use This Switch Actuation Test Tool
- Focus: Click the Active Key Zone, then press and release any key to start tracking key down and key up events.
- Measure: The tool records press duration, release lag, input response, and updates stats in real time.
- Analyze: View consistency score, average speed, and keystroke log with fast, normal, slow, and stuck status.
- Visualize: Use the live histogram to understand your typing speed distribution and patterns.
- Control: Adjust stuck key sensitivity, reset the test anytime, or export CSV data for deeper analysis.

Key Press Duration (Actuation Time) Explained
Key Press Duration (Actuation Time) is the time between a key down event and a key up event, showing how long a key is held. It reflects actuation timing, input response, and key travel behavior, helping measure typing speed, latency, and switch performance. Short duration means faster input, while longer duration may indicate slower response or deeper press toward bottom-out.
Release Speed & Key Reset Time Explained
Release Speed & Key Reset Time show how quickly a key returns after a key up event and becomes ready for the next press. Faster reset improves input response, reduces latency, and allows smoother repeated keystrokes, especially in gaming and fast typing. Slower reset can delay rapid inputs, particularly when the switch takes longer to move back from the actuation point to its original position.
Consistency Score (Typing Stability) Explained
Consistency Score (Typing Stability) shows how evenly your key press duration and release timing stay across inputs. Lower variation in latency and steady input response produce a higher score, indicating a stable typing rhythm and reliable switch performance. A low score suggests irregular presses, uneven speed, or inconsistent keystroke patterns.

Keyboard Latency & Input Response Explained
Keyboard Latency & Input Response show how quickly a keystroke is registered after a key down event. Lower latency gives faster input response, improving typing speed and gaming performance. Higher latency creates delay between press and action, often due to slow switch response, system lag, or delayed key up events, reducing keystroke accuracy and responsiveness.

Mechanical vs Membrane Keyboard Actuation Differences
| Feature | Mechanical Keyboard | Membrane Keyboard |
|---|---|---|
| Actuation Method | Individual switch-based actuation | Pressure pad (rubber dome) |
| Actuation Time | Faster and more precise | Slower and less consistent |
| Key Press Duration | Stable and responsive | Varies with pressure |
| Key Reset Speed | Quick reset for rapid input | Slower reset time |
| Input Response | Low latency, accurate | Higher latency, softer response |
| Consistency Score | High typing stability | Lower consistency |
| Typing Feel | Tactile / Linear / Clicky options | Soft and mushy feel |
| Gaming Performance | Better for fast-paced gaming | Not ideal for competitive gaming |
Keyboard Problems This Tool Can Detect (Input Lag, Stuck Keys & More)
- Input Lag: Delay between key down event and system response, often caused by high latency or slow input processing.
- Double Key Press: One press registers twice due to unstable actuation point or inconsistent key reset.
- Slow Response: Longer key press duration or delayed release speed affecting overall input response.
- Stuck Keys: Key held beyond threshold, showing failure in switch reset or abnormal key travel behavior.
Improve Your Keyboard Performance Using This Tool
Using this tool, you can analyze key press duration, release speed, and input response to find delays or inconsistencies. By tracking latency, consistency score, and keystroke patterns, you can adjust your typing style, detect stuck keys, and improve speed and accuracy. Regular use builds better typing rhythm, faster reactions, and more reliable keyboard performance for gaming and everyday use.

Frequently Asked Questions
Is 0.1 mm actuation good?
A 0.1 mm actuation point is extremely sensitive and can register inputs very quickly, but it may cause accidental key presses due to small finger movements. This can affect control in gaming, especially during precise actions where unintended inputs can reduce accuracy.
How to test actuation force?
Actuation force is typically tested using a specialized device that applies controlled pressure to a key while measuring force and travel distance. In real use, tools like a switch actuation test simulate key presses to analyze input response, timing, and consistency.
Is 2 mm actuation good?
A 2 mm actuation point is considered balanced, offering a mix of speed and control. It is common in many mechanical switches and works well for both typing and gaming, providing reliable input without being too sensitive.
Is low actuation force better?
Low actuation force allows faster and lighter key presses, which improves typing speed and gaming performance. However, higher force switches offer better control and accuracy, so the best option depends on your usage and preference.
Is 40g actuation force good?
A 40g actuation force is ideal for fast and responsive input, making it popular for gaming and long typing sessions. It requires less effort to press keys, helping reduce fatigue while maintaining quick input response.
