HMX Retro Joker Linear Switches

This linear switch is designed for users who prefer a smooth keystroke with a distinct clacky sound. It suits typists or keyboard enthusiasts looking for a return to the classic HMX sound profile, characterized by sharp bottom-out and top-out clicks. It is less ideal for those seeking a quiet or tactile experience.

Feel & Sound

• Linear feel with no tactile bump or click, providing smooth keypresses.
• Clacky sound profile due to full P3 housing and POM stem, emphasizing both bottom-out and top-out clicks.
• Sound is sharper and more defined compared to newer HMX molds that produce louder, fuller tones.

Actuation Characteristics

• Moderate operating force around 45g, offering a balance between light and firm keypresses.
• Pre-travel of 2.0mm and total travel near 3.5mm, standard for linear switches.
• Bottom-out force slightly higher than actuation force, contributing to the tactile feedback on keypress completion.

Build Quality

• Housing made entirely of P3 plastic, which affects sound and durability.
• POM stem material, common in clacky switches for its sound and smoothness.
• Spring is a 22mm KOS single-stage extended type, influencing force curve and keypress feel.
• Factory lubed with mixed GPL105 and GPL205 on critical parts, reducing initial scratchiness and improving smoothness.

Trade-offs

• Clacky sound may be disruptive in quiet environments or shared workspaces.
• Linear design lacks tactile feedback, which some users may find less engaging for typing.
• Unknown compatibility details and modification potential beyond factory lubrication.
