Is Corsair K57 Keyboard Mechanical or Membrane? (Switch Type)

Is the Corsair K57 mechanical?
No. The Corsair K57 uses rubber-dome membrane switches, not mechanical switches such as Cherry MX or Gateron.
No, the Corsair K57 is NOT a mechanical keyboard. This is the #1 source of buyer confusion and disappointment in this Corsair K57 review.
The Corsair K57 uses rubber dome membrane switches, not mechanical switches. Despite being marketed as a “gaming keyboard” with RGB lighting and macro keys, it doesn’t feature Cherry MX, Gateron, or any mechanical switches.
Why the Confusion?
Many buyers assume “gaming keyboard” equals “mechanical keyboard.” Corsair’s marketing emphasizes wireless performance and RGB aesthetics but doesn’t prominently display the switch type, leading to misunderstandings across Amazon reviews and Reddit threads.
What Does This Mean for You?
| Aspect | Membrane (K57) | Mechanical (K63, K70) |
|---|---|---|
| Key Feel | Soft, “mushy,” requires more force | Crisp, tactile, responsive |
| Sound | Quiet, suitable for offices | Louder, clicky (depends on switch) |
| Lifespan | 20 million keystrokes | 50-100 million keystrokes |
| Typing Fatigue | Higher (heavier actuation) | Lower (easier actuation) |
| Price (2025) | $90-100 | $110-150 |
Bottom Line: If you’ve used mechanical keyboards before and enjoyed them, the Corsair K57 will feel disappointing. If you’re upgrading from a basic $20 office keyboard, you’ll appreciate the RGB and wireless features.

- Fast Charge: Not supported
- Charging Port: Micro-USB (outdated; competitors use USB-C)
Can You Use It While Charging?
✅ Yes. The Corsair K57 functions as a wired keyboard while charging, so a dead battery won’t interrupt gameplay.
Corsair K57 Battery Replacement: The Big Problem
Corsair K57 battery replacement:
Corsair does not officially support battery replacement for the K57. The internal battery is not user-replaceable, and once it degrades, the keyboard must be used wired or replaced.
Searching for “corsair k57 battery replacement“? Here’s the unfortunate truth:
❌ Corsair does not officially support battery replacement.
What This Means:
- When the battery fails (typically 2-3 years), Corsair support offers discount codes for a new keyboard instead of repair options
- The keyboard becomes electronic waste once the battery dies
- DIY replacement is possible but requires soldering and voids warranty
Community Workaround (Advanced Users Only):
Reddit’s right-to-repair community has documented that the K57 uses a standard 18650 Li-ion cell. Skilled users have successfully replaced batteries by:
- Disassembling the keyboard (voiding warranty)
- Desoldering the old battery
- Soldering in a new 18650 cell (available on Amazon)
Success Rate: Community reports suggest approximately 70% success rate; remaining attempts result in damage during disassembly.
Note: Battery replacement information is included for educational purposes only and is not endorsed by Corsair.
Our Take: This is a significant long-term concern. If you want a keyboard that lasts 5+ years, consider the Logitech G613 with replaceable AA batteries or check our alternatives section.
