Durock Silent Linear Dolphin is a linear mechanical switch from Durock released in May 2020 with a 45 gf operating force and 2 mm pre-travel, 3.8 mm total travel, and a manufacturer rating of At least 50 million keystrokes.
Three focused profiles from published switch specifications. No overall score is generated because feel and use case are personal.
Measures actuation, travel, and force. Shorter, lighter movement favors speed. Advanced input features add capability.
Measures bump or click intensity. It uses feel type and tactile-force rise. Higher scores mean stronger feedback.
Measures published lifespan evidence. It uses documented construction details. It does not predict real-world reliability.

Long recognized as a benchmark silent linear option, Durock Silent Linear Dolphin uses specialized silicone silencing rings on the stem rails. A 45gf actuation force and 62gf bottom-out spring across 3.8mm of travel provide a smooth and controlled keystroke with plenty of return snap. Keystrokes generate a hushed, cushioned thud that completely eliminates high-frequency plastic clatter. JWK mold quality ensures fluid travel with virtually zero scratchiness even before aftermarket lubrication. Enthusiasts often mount this switch on an FR4 plate with dense sound absorbing foam for an ultra-quiet typing build.

Explore switches with similar technology, feel, form factor, operating force, and travel.
The Durock Silent Linear Dolphin is a Mechanical switch from Durock with a Linear feel, so its keypress character is primarily defined by that mechanism and feedback style.
The Durock Silent Linear Dolphin has an operating force of 45 gf. That sits in the common middle range for everyday typing and gaming.
The Durock Silent Linear Dolphin has a pre-travel of 2 mm. Shorter actuation distances usually feel quicker because the key registers earlier in the press.
The Durock Silent Linear Dolphin has a total travel distance of 3.8 mm. Total travel describes the full stroke from rest to bottom-out.
The Durock Silent Linear Dolphin is listed as 5-pin, MX keycap compatibility is yes, and hot-swap compatibility is yes. Always match the switch pins and keyboard PCB/socket before buying.
Yes. The Durock Silent Linear Dolphin is listed as factory lubed. Factory lubrication can affect out-of-box smoothness and sound, but its effect can vary with the keyboard build and keycaps.
Available sound-related specs for the Durock Silent Linear Dolphin include sound profile: Muted, sound level: Silent. Case, plate, keycaps, and desk mat can still change the final keyboard sound.
The Durock Silent Linear Dolphin is rated for At least 50 M cycles. Lifespan ratings are lab-cycle estimates, so real-world durability can also depend on build quality and usage.
The Durock Silent Linear Dolphin lists top housing: PC, bottom housing: Polymer Nylon, stem: POM, contact: Gold-plated alloy. These parts influence feel, sound, wobble, and long-term switch consistency.
