Akko U1 Switches Launch: POM Composite for Thicker Sound

Akko introduced the U1 series mechanical keyboard switches on July 17, offering builders a new material option for custom keycaps. The switches use a polyoxymethylene composite to improve actuation smoothness and consistency across the board. This matters to enthusiasts who prioritize tactile feedback and acoustic tuning in their builds. The upgrade targets users looking to reduce unwanted noise while maintaining a solid typing experience.

New POM switches offer thick sound and smooth actuation

The U1 series features an iterative cylindrical stem and guide rail structure to ensure precise alignment. Akko also upgraded the POM upper housing to further refine the switch’s mechanical behavior. These design changes aim to deliver a full and thick keystroke sound profile. The company plans to integrate these switches into upcoming keyboard models, including the 5075 V5.

Specifications

• Material: POM (Polyoxymethylene) composite
• Design Features: Iterative cylindrical stem and guide rail structure; upgraded POM upper housing
• Acoustic Profile: Full and thick keystroke sound; reduced spring noise and resonance
• Variants: Cream Yellow (Linear), Piano (Linear), Crystal Silver (Linear), Cream Purple (Tactile)
• Optical Design: Light guide pillar diffusion structure to reduce light loss and dark areas

Akko released four distinct variants to cover different typing preferences and aesthetic needs. The linear options include Cream Yellow, Piano, and Crystal Silver switches. Builders can also choose the Cream Purple variant for a tactile actuation feel. Each variant utilizes the same POM composite base to ensure consistent performance characteristics.

The switches incorporate a light guide pillar diffusion structure to manage LED illumination. This optical design reduces light loss and minimizes dark areas around the key stem. The result is a more uniform backlight appearance for users with RGB-enabled keyboards. Akko will apply the U1 series switches to the upcoming new keyboard, with global availability marked as TBD.

We have been tracking U1 Series Mechanical Switches closely — see our earlier coverage on AKKO Launches 5075 V5 Magnetic Switch. The U1 series represents a focused update on material science rather than a complete architectural overhaul. Buyers seeking smoother linear action or a thicker acoustic profile may find these switches suitable for their next build.
