Gateron EF Fast Silver Linear Switches

This linear switch suits users who want a light, fast keypress with minimal resistance. It is appropriate for gamers seeking quick actuation and typists who prefer smooth, uninterrupted keystrokes. The low actuation force and short pretravel support rapid input, while factory lubrication reduces initial scratchiness.

Feel & Sound

• Linear design provides a smooth, consistent keystroke without tactile bumps or clicks.
• Factory lubrication helps reduce scratchiness, resulting in a quieter, softer sound profile compared to unlubed switches.
• Bottoming out feels relatively light due to the moderate total travel distance, which may reduce finger fatigue during extended use.

Actuation Characteristics

• Light actuation force of 45g allows for quick keypresses with less finger effort, beneficial for fast typing or gaming.
• Short pretravel of 1.2mm means the key registers input early in the press, improving responsiveness.
• Total travel of approximately 3.4mm balances speed with enough distance to avoid accidental keypresses.

Build Quality

• Polycarbonate top housing and nylon bottom housing provide a stable and durable structure.
• POM stem material is smooth and wear-resistant, contributing to consistent feel over time.
• Factory lubrication is applied, which can reduce initial scratchiness and noise but may wear off with heavy use.

Compatibility

• PCB mount with 5 pins ensures secure installation on compatible PCBs.
• Supports SMD LEDs, allowing for backlighting customization.
• Plate mount compatibility is noted, but hot-swap friendliness is unknown.

Trade-offs

• Force variance of 15 cN may cause slight inconsistency in key feel across switches.
• Linear switches lack tactile feedback, which some typists may find less satisfying or prone to accidental presses.
• Potential stem wobble or spring noise is unknown, so some users might experience minor instability or ping.

Use Cases

• Well suited for fast-paced gaming where quick actuation and smooth keypresses improve performance.
• Good for users who prefer a quiet, light typing experience without tactile interruptions.
• Less ideal for those who want tactile or clicky feedback to confirm keypresses.
