Kailh Low Profile Choc Red V2 Linear Switches

The Kailh Choc Red V2 is a low profile linear switch designed for users who want a smooth, consistent keystroke with a shorter overall height. It suits typists and gamers looking for a low profile switch compatible with traditional MX-style PCBs, offering a linear feel without tactile bumps or clicks. This switch fits well in slim keyboards or setups aiming to reduce key travel distance while maintaining familiar MX compatibility.

Feel & Sound

• Delivers a smooth, linear keypress without tactile feedback, favoring users who prefer consistent resistance throughout the stroke.
• Lower travel distance reduces finger movement, which can speed up typing or gaming actions.
• Sound profile is quieter than many tactile or clicky switches, though exact noise levels depend on keyboard build and keycaps.

Actuation Characteristics

• Light actuation force of 43g supports quick key presses with less finger fatigue.
• Pre-travel of 1.3mm and total travel of 3.2mm shorten the distance keys move compared to standard MX switches, aiding faster input.
• Bottoming out feels softer due to shorter travel, which may reduce impact noise and finger strain.

Build Quality & Compatibility

• Top housing made of polycarbonate and bottom housing of nylon provide durability and stability.
• Stem constructed from POM (polyoxymethylene) offers smooth sliding and reduced friction.
• Designed for traditional MX PCBs, making it compatible with many existing keycaps and keyboard layouts.
• Supports SMD LEDs for backlighting integration.

Modification Potential & Trade-offs

• Not factory pre-lubed, so additional lubrication may improve smoothness and reduce scratchiness, which is the slight friction felt during keypress.
• Stem wobble and spring noise are unknown, so some break-in or modding might be needed for optimal feel.
• Low profile design may limit compatibility with some keycap profiles or custom setups that expect standard switch height.

Use Cases

• Good for users wanting a low profile, linear switch for fast, smooth keypresses in gaming or typing.
• Less ideal if tactile feedback or audible clicks are preferred.
• Suitable for slim keyboards or custom builds that require MX-compatible low profile switches.
