Kailh Red Bean Pudding Linear Switches

This linear switch offers a light and smooth keystroke suited for users who prefer a consistent, non-tactile typing experience. It fits well for typists and gamers who want a responsive keypress without tactile bumps or clicks. The switch is not silent, so it may be less ideal for quiet office environments.

Feel & Sound

The switch provides a linear feel with no tactile feedback, resulting in a smooth and consistent keypress. It produces audible sound typical of box-style switches but is not designed to be silent. The sound profile is moderate, without a pronounced thock or clack. Users seeking quiet operation should consider alternatives.

Actuation Characteristics

With a relatively low actuation force, the switch requires light pressure to register inputs, which can reduce finger fatigue during long typing sessions. The short pre-travel distance allows for quick key activation, while the total travel length is standard, offering a familiar typing depth. The bottom-out feel is firm due to the 13mm stainless steel spring, providing clear feedback on keypress completion.

Build Quality

The switch uses a polycarbonate top housing and a POM bottom housing, materials known for durability and smoothness. The POM box-style stem helps reduce friction, contributing to the linear feel. The spring is stainless steel and relatively long, supporting consistent performance over time. The switch comes unlubed, which may result in some initial scratchiness that can be improved with aftermarket lubrication.

Compatibility

This is a PCB-mounted switch with five pins, compatible with most standard MX-style mechanical keyboards. It supports SMD LEDs and is light pipe compatible, allowing for effective backlighting integration. Hot-swap compatibility is unknown.

Trade-offs

The switch is unlubed from the factory, which may cause scratchiness until broken in or lubricated. It is not silent, so it may not suit noise-sensitive environments. The linear design lacks tactile feedback, which some users may find less engaging for typing. Unknown factors include hot-swap compatibility and magnetic or capacitive features.
