Gateron KS 37 Dual Rail FOX HE Linear Switches

The Gateron KS37 DualRail FOX Magnetic HE is a linear mechanical switch designed for users who prefer smooth keystrokes with consistent force and long durability. It suits typists and gamers seeking a quiet, fluid keypress without tactile bumps. The magnetic element may appeal to those interested in subtle feedback variations and enhanced stability during key travel.

Feel & Sound

This switch offers a linear feel, meaning keystrokes are smooth without tactile feedback or clicks. The magnetic component can provide a slight sense of resistance or return, which may reduce wobble and improve key stability. Sound is generally quiet, making it suitable for office or shared environments. The bottoming feel is defined by a moderate force increase, which some users may find more comfortable for extended typing sessions.

Actuation Characteristics

The switch actuates with an initial force around 30gf, rising to about 50gf at the bottom. This force curve supports controlled keypresses without requiring excessive effort. Total travel is approximately 4mm, which is standard for most mechanical switches, allowing familiar key depth. Operating travel is self-defined, indicating potential variation depending on keyboard implementation.

Build Quality & Durability

It features a factory self-lubricating design, reducing initial scratchiness and break-in time. The switch is rated for over 150 million keystrokes, indicating high durability for heavy use. Specific materials for housing and stems are unknown. The magnetic element may contribute to longer-term stability and reduced stem wobble.

Compatibility

The switch is compatible with various keyboard brands including ATK68, Higround, Yuki Aim, Kzzi, Waizowl, and Keychron. Details on mount type and LED compatibility are unknown. Users should verify compatibility with their specific keyboard model before purchase.

Trade-offs

While factory lubrication helps reduce scratchiness, the magnetic mechanism may alter the feel in ways not preferred by all linear switch fans. The self-defined operating travel could lead to inconsistencies across different keyboards. Unknown factors include spring ping and exact housing materials, which may affect long-term sound and feel.
