Gateron Jupiter Brown Tactile Switches

This tactile mechanical switch suits typists and office users who want noticeable feedback without click noise. It offers a moderate actuation force and a defined bump, helping reduce accidental key presses while maintaining a quiet profile. The clear housing supports LED lighting, making it compatible with illuminated keyboards.

Feel & Sound

• Provides a tactile bump without click noise, delivering feedback without added sound.
• Quiet operation, suitable for shared or noise-sensitive environments.
• Moderate tactility helps improve typing accuracy without being too heavy or scratchy.

Actuation Characteristics

• Actuates at 2.0 mm with a total travel of 4.0 mm, balancing responsiveness and key travel distance.
• 55g actuation force offers a firm but not tiring press, suitable for extended typing sessions.
• Single-stage spring provides consistent resistance without multiple force peaks.

Build Quality

• Stem made from POM, known for smooth sliding and durability.
• Housing combines polycarbonate top and nylon bottom, supporting LED diffusion and structural stability.
• Gold alloy contact points enhance electrical reliability over time.
• Factory lubed, reducing initial scratchiness and improving smoothness.

Compatibility

• Plate mount design fits most standard mechanical keyboards.
• Five-pin PCB mount ensures secure installation and prevents switch wobble.
• Clear top housing supports SMD LED lighting for backlit keyboards.

Trade-offs

• Not silent, but quieter than clicky switches; may still produce some sound during bottom-out.
• Force variance of 15 cN means slight inconsistency between switches, which may affect uniformity.
• Unknown long-term durability beyond rated 80 million operations.
