JWICK JWK Ultimate Black Linear Switches (90 pieces)

JWICK Ultimate Black Linear

JWICK Ultimate Black Linear are smooth and quiet linear mechanical switches, designed for users who prefer consistent key travel without tactile bumps or clicks. They are an excellent choice for both typing and gaming, especially if you are looking for a perfect balance between fast response and comfort, combined with a slightly firmer bottom-out force. This model is a great option for custom keyboard enthusiasts who need a reliable 5-pin mount and appreciate the presence of factory lubrication for immediate smoothness.

Feel and Sound

• Uninterrupted Travel: The switch offers entirely linear travel, meaning the keys press smoothly from top to bottom without any tactile feedback.

• Muted Acoustics: Factory lubrication successfully reduces the feeling of scratchiness, ensuring a quiet and muted sound profile.

• Solid Finish: The bottom-out force is moderately firm, providing a stable but by no means harsh end to each keystroke. This makes the switches extremely comfortable for long computer sessions without generating excessive noise.

Actuation and Characteristics

• Moderate Pressure: With an actuation force of 59g and a total travel of 4.0mm, the switch requires moderate pressure to register a command.

• Progressive Spring: The progressive spring design means that resistance increases slightly towards the end of the travel, which helps prevent accidental presses while maintaining excellent responsiveness.

• Definitive Bottom-Out: The bottom-out force is 63.5g, which provides a clear physical sensation of a completed keystroke without the need for a tactile bump.

Build Quality

• Combined Housing: The construction combines polycarbonate (PC) in the upper part and Nylon PA66 in the base, which contributes to high durability and excellent sound dampening.

• Minimum Friction with POM Stem: The stem is made of POM material, known for its low coefficient of friction, which enhances the smooth gliding of the key.

• Gold-Plated Contacts: Gold-plated metal contacts improve electrical reliability and ensure a longer lifespan for the components over time.

Compatibility

• Stable Mount: The switch uses a 5-pin (5-pin) design for PCB mounting, guaranteeing secure and stable attachment in most custom mechanical keyboards.

• Wide Adaptability: The model is fully compatible with standard MX-style keycaps and supports common LED backlight configurations.

• Note: Detailed information on its compatibility with specific Hot-Swap sockets is unavailable.

What to Consider (Possible Trade-offs)

• While factory lubricated, some more demanding enthusiasts might consider additional manual lubrication or filming to minimize stem wobble, which is typical for linear switches.

• The slightly higher bottom-out force might not appeal to users who strongly prefer an extremely light and airy press.

• There is no detailed data on whether spring ping or other extraneous noise artifacts appear after very prolonged use.
