Gateron KS 20 HE Linear Switches

The Gateron KS20 Magnetic HE is a linear mechanical switch featuring Hall Effect magnetic sensing technology. It suits users who want a smooth, consistent keystroke with adjustable pre-travel and a contactless actuation method, which can offer durability and reduced signal degradation over time. This switch is appropriate for typists and gamers seeking a quiet, linear feel without tactile bumps or clicks.

Feel & Sound

• Linear and ultra-smooth keystroke with no tactile feedback or audible click.
• Quiet operation suitable for office or shared environments.
• Bottom-out force provides a solid but not harsh end to each keypress.

Actuation Characteristics

• Free setting of pre-travel allows users to customize the initial key travel before actuation, potentially improving responsiveness.
• Total travel distance is standard, offering familiar key movement length.
• Operating force varies by variant, with lighter and heavier options to suit different finger strengths and preferences.

Technology & Durability

• Uses Hall Effect magnetic sensors for contactless key actuation, reducing wear on electrical contacts and potentially extending switch lifespan.
• Magnetic sensing can improve signal consistency compared to traditional mechanical contacts.

Trade-offs

• Linear feel may be less satisfying for users who prefer tactile or clicky feedback.
• Unknown details on factory lubrication and stem wobble, which can affect smoothness and noise.
• Customization beyond pre-travel adjustment, such as modding or lubing, is undocumented.

Use Cases

• Good for users wanting a smooth, quiet typing experience with customizable actuation depth.
• Suitable for gaming due to linear response and adjustable pre-travel.
• Less ideal if tactile feedback or audible clicks are preferred.
