MMD Princess Linear Switches

The MMD Princess Linear is a smooth linear switch suited for users who prefer a consistent, quiet keystroke without tactile feedback. It fits well for typists and gamers seeking a deep, crisp bottom-out feel with moderate actuation force. The switch’s design emphasizes smoothness and a solid build, making it a good choice if you want a refined linear experience with less stem friction.

Feel & Sound

• Delivers a smooth keystroke due to a PTFE-coated stem, which reduces friction compared to standard POM stems.
• Produces a deep and crisp sound on bottom-out, which may appeal to users who like audible feedback without clickiness.
• Lacks tactile bumps or clicks, so it is quieter than tactile or clicky switches but not silent.

Actuation Characteristics

• Requires moderate force to actuate, balancing responsiveness and resistance for controlled keypresses.
• Pre-travel and total travel distances are typical for linear switches, supporting smooth and predictable key movement.
• Bottom-out force is slightly higher than actuation force, providing a noticeable but not harsh landing.

Build Quality

• Uses a combination of modified polycarbonate top housing and PA66 bottom housing for durability and sound shaping.
• Stem material blends POM and PTFE, enhancing smoothness and reducing stem friction, which can improve long-term feel.
• Spring type is unknown, but the force curve suggests a consistent linear resistance.

Trade-offs

• May not satisfy users who want tactile or clicky feedback, as it is purely linear.
• Sound profile is not silent, so it might be less ideal in very quiet office environments.
• Unknown factory lube quality, so additional lubrication might be needed for optimal smoothness.
