CROWN / SAMDUCKSA SDB-203C Silent Cherry 30 mm Screw-in button - Clear Smoke

SamducksaSKU: SDB-203C-S-30-CS



What's new about "203-Silent"?

Thanks to customers' support for the original SDB-202 series, Samducksa decided to go one step further and develop a new series called SDB-203-Silent. By changing the inner material of the button from plastic to silicone, the noise generated when button mashing has been reduced greatly compare to the original SDB-202 button. Also, newly molded rim that allows you to not only screw down with button nut but also snap down the button. This prevents the button get loose over time. The button color comes with Clear Colors (CR/CB/CY/CG/CW/CS).

Would the real SAMDUCKSA please stand up?

The artistes formerly known as CROWN, SAMDUCKSA is a name we should all know by now after being a force to reckon with in the Korean arcade parts world. SAMDUCKSA dropped the moniker CROWN starting with the launch of the SDL-301 series of joysticks and their first mechanical keyboard switch based button series, the SDB-201.

201, 202 what's the difference?

Well, I'm very glad you decided to ask! The SDB-201 series was based around Futaba MA mechanical keyboard switches. While not a big name in the mechanical keyboard industry these days, they are good switches and will last a lifetime. The downside is, they're on the slower side with a deep engage at 3 mm and 4 mm total travel. High precision and good performance, but other switches are faster which is where the SDB-202 Cherry series come into the picture. SAMDUCKSA upgraded the SDB series of buttons by choosing the enthusiast acclaimed, high performance Cherry MX Speed Silver button, pictured below.

How about some Cherry MX Speed Silver specs?


  • 45 gram operating force
  • 1.2 mm actuation point
  • 3.4 mm total travel (throw)
  • Linear operation
  • No tactile feedback

Why walk when you can fly? Let's take a high performance switch and make it better.
