The Brown switches are about halfway between a typing and a gaming switch. Unlike the black switches, the browns have a soft, tactile bump about halfway through the key press. Some people prefer them for gaming since it enables you to double tap faster and typists like them because they still have a good tactile feedback, but the audio feedback isn’t quite as noticeable as Blue switch. The Brown switches have a softer click when depressed and require less force to actuate. The Das Keyboard tactile-soft series utilizes Brown switches.
