Kailh Blueberry $3.50 / 10

The Kailh Blueberry takes the click bar mechanism from the Box White series and applies it to a heavier spring in a standard housing design. At 62g actuation, it is one of the heavier clicky switches available in mainstream production, targeted at typists who want a clicky switch with real weight behind each keypress rather than a featherlight click.

The click bar mechanism works by deflecting a metal bar as the stem travels down, creating a sharp, crisp click when the bar snaps past the ramp on the stem. This mechanism produces a more defined and consistent click than the click jacket design used in Cherry MX Blue switches. The tactile feedback arrives simultaneously with the click sound, giving clear, unambiguous actuation confirmation.

Sound character is a bright, sharp click that carries clearly through most office environments. At 62g actuation, the Blueberry hits harder than Box Whites or MX Blues, which some users find more satisfying and others find tiring. Heavy typists who apply significant force to each key will find the actuation weight appropriate. Light-touch typists may find 62g fatiguing for extended sessions.

For programming or writing sessions where deliberate, confident keypresses are the norm, the Blueberry is an excellent choice. The click provides positive confirmation of each character entered, reducing typos for those who benefit from audible-tactile feedback. The PC housing produces a bright resonance that complements the click sound without muddying it.

Like most clicky switches, Blueberries do not benefit from lubing the click mechanism. You can lube the stem rails very lightly to reduce any non-click friction, but touching the click bar area with lube will dampen the click inconsistently. Accept these as switches you evaluate stock and deploy as-is — their value comes from the mechanism, not from lubing potential.
