MMD Princess V4 Linear Switches

The MMD Princess Linear V4 is a smooth linear switch designed for users who want a consistent keystroke with enhanced RGB lighting effects. It suits typists and gamers who prefer a quieter, non-tactile experience but still want some audible feedback from their keyboard. The switch offers moderate actuation force and a slightly clacky sound profile, making it a balanced choice for everyday use and light gaming.

Feel & Sound

• The switch delivers a smooth keystroke with reduced stem wobble, which improves stability and typing consistency.
• Its linear design means no tactile bump or click, favoring fluid key presses.
• The bottom housing uses polycarbonate material, producing a poppy and clacky sound that is more pronounced than earlier versions.
• The sound profile may be noticeable in quiet environments, so it is less ideal if near-silent operation is required.

Actuation Characteristics

• Moderate actuation force helps prevent accidental key presses while avoiding finger fatigue during extended typing.
• Pre-travel and total travel distances support a responsive yet comfortable typing rhythm.
• The bottom-out feel is firm with a distinct sound, which some users may find satisfying or distracting depending on preference.

Build Quality & Lighting

• Both top and bottom housings are made from polycarbonate, enhancing durability and light diffusion.
• A built-in light diffuser improves RGB shine-through, making backlighting more vibrant and even.
• The stem is made from LY material, contributing to smooth keypresses and reduced wobble.

Trade-offs

• The clacky sound profile may not suit office environments or users seeking quiet switches.
• While wobble is reduced, some minor stem movement may still be perceptible to sensitive users.
• Unknown factory lubrication quality, so additional lubing might be needed for optimal smoothness.

Use Cases

• Good for users who want smooth linear switches with enhanced RGB lighting effects.
• Suitable for gaming and typing where audible feedback is acceptable or preferred.
• Less ideal for quiet office settings or users who want tactile or clicky feedback.
