Gateron Sage Linear Switches

The Gateron Sage Linear switch is a custom mechanical keyboard switch designed through a collaboration between Unikeys and Mori. Developed as a result of experimenting with different switch components, this linear switch combines unique materials and molds to deliver a distinctive typing experience characterized by smooth travel, reduced stem wobble, and a satisfying sound profile.

Design and Construction

This switch features a blend of proven Gateron components, utilizing the Sea Salt Smoothie POM stem and the KS-3 Milky Yellow Pro housing mold. The combination of these elements results in a switch that stands out for both its feel and acoustics.

• Stem Material: Modified POM (Polyoxymethylene) for smooth actuation
• Top Housing: Modified Milky Nylon for a balanced sound signature
• Bottom Housing: Modified Nylon for structural stability
• Mold: Sea Salt Smoothie stem mold paired with KS-3 Milky Yellow Pro housing mold

Performance Characteristics

The switch is engineered to provide a refined linear feel with a solid bottom-out, thanks to its long pole design. It offers a smooth keypress with minimal stem wobble, making it suitable for both typing and gaming.

• Switch Type: Linear
• Operating Force: 47±2g
• Bottom-out Force: 55±2g
• Pre-travel Distance: 2.0mm
• Total Travel Distance: 3.6±0.2mm
• Spring: 18mm KOS single-stage extended spring

Sound and Feel

One of the defining features of this switch is its "thocky" and satisfying sound signature. The material and mold combination produces a deep, pleasant acoustic profile, while the long pole stem ensures a solid and consistent bottom-out feel. The travel is exceptionally smooth, with less stem wobble compared to typical linear switches.

• Deep, satisfying "thock" sound
• Consistent and solid bottom-out
• Smooth keypress throughout the travel
• Reduced stem wobble for a stable typing experience

Factory Lubrication

To enhance smoothness without over-lubrication, the factory lube process has been carefully adjusted. Lubricant is applied only to the stem legs, spring, and leaf, resulting in a clean and consistent feel right out of the box.

• Factory lubed with reduced amount for optimal performance
• Lube applied to stem legs, spring, and leaf only

Key Features Summary

• Custom-designed linear switch
