HMX QQ PEI Bumblebee Linear Switches

The HMX QQ PEI Bumblebee Linear is a smooth linear switch suited for users who prefer a consistent, quiet keystroke with a crisp sound profile. It fits typists and gamers seeking a balanced feel with moderate actuation force and a clean acoustic signature. The switch’s factory lubrication and dual-material housing aim to deliver a controlled, smooth experience with reduced scratchiness and clear bottom-out feedback.

Feel & Sound

• Linear travel provides a smooth keystroke without tactile bumps or clicks.
• The dual-material housing, combining nylon and PEI, produces a crisp and lively top-out and bottom-out sound.
• Sound is clear and consistent across keyboards, offering a balance between sharpness and fullness.
• Factory lubing reduces scratchiness, contributing to a smooth feel from the start.

Actuation Characteristics

• Moderate actuation force of 50g suits users who want a noticeable but not heavy keypress.
• Bottom-out force is slightly higher at 58g, providing a controlled, firm bottoming sensation.
• Total travel of 3.6mm with a 23mm spring length supports comfortable typing and gaming sessions.

Build Quality

• Top housing made from PEI, a durable and acoustically favorable material that is difficult to mold but enhances sound clarity.
• Bottom housing uses nylon with a PEI core, balancing sound fullness and crispness.
• Stem material is standard, supporting compatibility with common keycaps.
• Factory lubing ensures smooth operation without immediate need for additional lubrication.

Compatibility & Use Cases

• 5-pin design fits most PCBs and supports plate mounting.
• Good for users who want a smooth, consistent linear switch with a distinctive sound profile.
• Less ideal if you prefer tactile or clicky feedback, or if you require a very quiet switch for noise-sensitive environments.
