Alps Switches
Sound Tests
Alps switches are legendary in the mechanical keyboard community for their unique sound and feel. Whether you’re a collector of vintage keyboards or just curious about how these switches compare to modern options, my sound tests will help you explore the rich acoustics of Alps switches—all tested under the same conditions for accurate comparison.
Why My Alps Switches Sound Tests Are Reliable
I test every Alps switch on the same keyboards and setups to ensure consistency. Many sound tests online use different recording methods or inconsistent setups, making it difficult to compare switches fairly. My tests keep everything controlled so that the only difference is the switch itself.
All switches have been opened and softly cleaned (every part brushed) without any alterations. Switch sets are used and old, so the sound could differ from switches in a different state, but all switches are at least in a 7.5 out of 10 state. The comparison is not perfect, but it gives a good idea. The estimated price is based on averaging the prices asked on Mechmarket between 2019 and 2024; it serves as an indicator.
These Alps switches sound tests were conducted using an ADK64 keyboard with Apple Extended Keyboard PBT Keycaps, a Zenith Z150 modified with a ZENITHal PCB & Original keycaps, and finally with a Tofu60 aluminum case using the Paladin64 PCB and Tai-Hao Cubic Alps Double-Shot keycaps. During the tests, I performed a typing test and a slow bottom-out test to showcase the switch's sound and feel. I also conducted a decibel meter test to measure the switch's noise level with and without a keycap.
Alps Switches Sound Tests & Comparisons
Here, you can listen to sound tests of various Alps switches, from smooth linear variants to sharp, clicky designs. Some of the Alps switches I’ve tested include:
-
Alps SKCM Blue / White / Orange – Classic tactile and clicky switches found in vintage keyboards.
-
Alps SKCL Green / Yellow – Rare linear Alps switches with a smooth and deep sound.
-
Matias Click / Tactile / Quiet (coming soon) – Modern recreations of Alps switches for contemporary keyboards.
-
Alps Cream Damped – A quieter Alps switch with a unique feel.
-
Complicated vs. Simplified Alps – A direct sound comparison between early Alps switches and later cost-reduced versions.
Each test includes:
✔ Typing sound tests with three different keycap sets (Cherry, MT3, and SA profiles)
✔ Slow bottom-out test (conducted with and without a keycap)
✔ Decibel meter reading for sound level comparison (measured with and without a keycap)
Are Alps Switches Right for You?
Alps switches are great if you:
- Prefer distinct tactile feedback or deep linear switches
- Want a unique alternative to modern MX-style switches
- Are interested in keyboard restoration and collecting
FAQ: Alps Switches
How do Alps switches compare to Cherry MX switches?
Alps switches often have a more pronounced tactile feel, deeper sound, and unique designs compared to MX-style switches. However, they are harder to find and maintain.
Are Alps switches still made today?
No, original Alps switches are no longer in production, but Matias has developed modern recreations based on the Alps design.
What’s the best Alps switch for typing?
Many enthusiasts love Alps SKCM Orange for a smooth yet tactile typing experience, while Alps Blue offers a classic clicky feel similar to modern clicky switches.
Are Alps switches hard to find?
Yes, since they’re discontinued, Alps switches are mainly found in vintage keyboards. Some can be salvaged, but they often require cleaning and careful restoration.
