Keygeek Cera Linear Switches

The Keygeek Cera Linear is a high-performance mechanical keyboard switch designed for enthusiasts seeking a clacky, crisp sound profile and smooth linear action. This switch features a full POM construction with innovative material enhancements and a new housing mold, resulting in a refined typing experience.

Design and Construction

This switch is engineered with a focus on material quality and precision. Both the top and bottom housings are crafted from L4 POM using newly commissioned molds, ensuring tight tolerances and minimal stem wobble. The stem is made from modified POM infused with ceramic powder, which increases hardness and reduces surface friction for a smoother keystroke.

• Full POM construction (top housing, bottom housing, and stem)
• New housing molds for improved fit and reduced wobble
• Flat pole tip on the stem for a distinct clacky and crispy sound
• Modified POM stem with ceramic powder for enhanced durability and reduced friction

Sound Profile

The switch is designed to deliver a clacky and crisp acoustic signature, thanks to its flat pole tip and material choices. This makes it ideal for users who appreciate a more pronounced and lively typing sound.

• Clacky and crispy sound profile
• Flat stem tip for unique acoustics

Smoothness and Feel

To address the higher surface friction typical of full POM switches, the housing openings and stem holes have been precisely adjusted. This minimizes stem wobble and eliminates sluggishness, often referred to as the syringe effect. The result is a consistently smooth and responsive keystroke.

• Minimal stem wobble
• No sluggish or sticky feel
• Enhanced smoothness due to ceramic-infused POM stem

Factory Lubrication

A unique lubrication process is used for this switch. The stem is coated with a dry film lubricant, while the top housing is left dry to avoid any oily sensation. This approach ensures a smooth keypress without unwanted residue.

• Dry film lubrication on the stem
• Dry top housing for a clean feel
