Kailh Black Linear Switches

This linear switch offers a smooth, consistent keystroke with a moderate actuation force, making it suitable for users who prefer a straightforward typing or gaming experience without tactile bumps or clicks. It fits well for those who want a reliable, durable switch with a clean feel but do not require silent operation or factory lubrication.

Feel & Sound

The switch provides a linear feel, meaning keystrokes are smooth from top to bottom without tactile feedback. It produces a standard sound profile typical of unlubed linear switches, which is not silent and may be moderately audible during fast typing or gaming.

Actuation Characteristics

With a 60g actuation force and 2.00mm pretravel, the switch requires moderate pressure to register input, balancing responsiveness and fatigue. The total travel distance of 4.00mm allows for full keypress depth, offering a familiar typing experience. The force variance of 20 cN indicates some variability in actuation force, which may affect consistency slightly.

Build Quality

The stem is made of POM, a durable material known for smooth sliding, contributing to the linear feel. The switch is unlubed from the factory, so initial scratchiness or noise may be noticeable until broken in or modified. It is rated for 50 million operations, indicating long-term durability.

Compatibility

This is a plate-mounted switch compatible with standard MX-style keyboards. It supports both single LED and RGB backlighting variants. Hot-swap compatibility is unknown.

Trade-offs

Because it is unlubed, users may experience scratchiness or higher noise levels initially. The lack of silent or tactile features makes it less ideal for quiet office environments or users seeking feedback. Force variance may lead to minor inconsistencies between keys.

Use Cases

Well suited for gamers and typists who want a smooth, linear keypress with moderate resistance. Less ideal for those needing quiet operation or tactile feedback. Suitable for users willing to apply lubrication or modifications to reduce noise and improve smoothness.
