JWICK Ultimate Black Linear Switches

The JWICK Ultimate Black Linear is a smooth, quiet linear switch suited for users who prefer consistent keystrokes without tactile bumps or clicks. It fits well for both typing and gaming, especially if you want a balance between responsiveness and comfort with a slightly heavier bottom-out force. This switch is a good option for enthusiasts building custom keyboards who need a reliable 5-pin PCB mount and appreciate factory lubrication for immediate smoothness.

Feel & Sound

The switch offers a linear feel, meaning keystrokes are smooth from top to bottom without tactile feedback. Its factory lubrication reduces scratchiness, resulting in a quiet and muted sound profile. The bottom-out force is moderately firm, providing a solid but not harsh end to each keypress. This makes it comfortable for extended typing sessions and gaming without excessive noise.

Actuation Characteristics

With a 59g actuation force and a total travel of 4.0mm, the switch requires moderate pressure to register inputs. The progressive spring design means resistance increases slightly toward the bottom, which can help prevent accidental key presses while maintaining responsiveness. The 63.5g bottom-out force offers a tactile sense of keypress completion without a tactile bump.

Build Quality

The housing combines polycarbonate on top and nylon PA66 on the bottom, contributing to durability and sound dampening. The POM stem material is known for low friction, enhancing smooth key travel. Gold-plated contacts improve electrical reliability over time. These materials together support consistent performance and longevity.

Compatibility

The switch uses a 5-pin PCB mount, ensuring secure installation in most custom mechanical keyboards. It is compatible with standard MX-style keycaps and supports common LED configurations. Hot-swap compatibility is unknown.

Trade-offs

While factory lubed for smoothness, some users may prefer additional lubing or filming to further reduce stem wobble, which is common in linear switches and can affect feel. The slightly heavier bottom-out force may not suit those who prefer very light keypresses. Unknown if spring ping or other noise artifacts occur after extended use.
