Ktt Aqua Prime HE Linear Switches

This linear switch uses magnetic force instead of a traditional spring to control keypress resistance. It suits users who want a smooth, consistent keystroke with a unique magnetic bottom-out feel. It is plate mount only and may appeal to those looking for a different tactile experience without tactile bumps or clicks.

Feel & Sound

• Linear and smooth with no tactile bump or audible click.
• Magnetic force provides a controlled resistance at both initial press and bottom out, which may reduce harsh bottoming sounds.
• Sound profile is likely quieter than typical spring switches due to magnetic damping, but exact noise levels are unknown.

Actuation Characteristics

• Uses magnetic flux for initial resistance (90Gs) and stronger force at bottom out (520Gs), offering a distinct force curve compared to spring-based switches.
• Total travel is 3.5mm, standard for most mechanical switches, allowing familiar key travel distance.
• Magnetic bottom out may feel softer or more controlled than spring bottoming.

Build Quality

• Stem made of POM, a low-friction material that supports smooth keypresses.
• Top housing is polycarbonate, which can affect sound resonance and durability.
• Bottom housing uses nylon (PA66), known for durability and stability.

Compatibility

• Plate mount only, so it requires a compatible keyboard plate and is not PCB mount.
• LED compatibility and hot-swap friendliness are unknown.

Trade-offs

• Magnetic actuation may feel unfamiliar to users accustomed to spring switches.
• Potential for magnetic interference or altered feel over time is unknown.
• Scratchiness, spring ping, and wobble are unknown, so a break-in period or additional lubrication might be needed.

Use Cases

• Good for users seeking a smooth linear feel with a unique magnetic resistance.
• Less ideal for those who prefer tactile or clicky feedback.
• May suit office environments where quieter keypresses are preferred, but exact sound levels are unknown.
