Kailh Silent Box switches (Kailh CPG1511F) are sound-damped variations of the Kailh BOX switches. They can be identified by having a cylindrical shroud around the cruciform mount on the slider, unlike an undamped Box switch that has a rectangular shroud.

Description

The metal contacts inside the switch are encased in a box, which is wherefrom the box switches have got their name. The box is there to prevent dirt and dust from interfering with switch operation. Kailh claims that the switch has a IP56 protection rating.

Unlike true Cherry MX clones, there is only one ramping surface. Because this is in a corner of the slider, they tend to sit slightly twisted, but not enough to impede operation or smoothness.

The slider has rubber bumpers that provide sound-damping when bottoming out and rebounding up.

Key feel

The tactile Brown switches have been described by several reviewers as having tactile bump early in the key travel with a prominence somewhere in-between that of the Aliaz (boutique version of Gateron Silent Brown) and Zilents V2.
