Durock Dolphin Silent 62g Linear PCB Mount Switch

I have several of these and have tested them side by side with: Cherry MX Silent Red, Cherry MX2A Silent Red, Gecko, Gateron Silent Red 45g, Zeal Roselio Silent, TTC Silent Red 56g, and Gateron Zero Degree Full Silent 45 g. The Dolphin is the quietest of them all, by a noticeable margin, especially on return. The Dolphin feels really smooth out of the bag, but once installed, all the silent switches were pretty smooth imho. Oddly, the Dolphin gives a subjective impression of being very light, the lightest on my tester, even though some others have lower gram force ratings. Light transmission of the Dolphin was also the best on the tester, even though it does not have an LED window. If quietness is your main concern, the Dolphin is the best switch I have tested so far. In the end however, I stuck with the Cherry MX2A Silent Red because I mix silents on my modifiers with tactiles on my alphas, and once installed, the Dolphins just seemed too light in comparison with my Baby Kangaroos and Holy Panda X's. Also the Cherry's are made in Germany with time-tested quality control.

These are incredibly quiet. I’ve tried Cherry MX Silent Red and TTC Silent Frozen, and these are the quietest. The 62g spring makes for a wonderful typing experience.
