Gateron Jupiter Banana Tactile Switches

This tactile mechanical switch suits users seeking a noticeable bump without click noise, such as typists who want feedback but prefer a quieter experience. It requires moderate force to actuate, making it suitable for those who favor deliberate key presses over light or heavy resistance. The switch supports LED lighting and plate mounting, fitting common custom keyboard builds.

Feel & Sound

• Delivers tactile feedback with a defined bump, aiding typing accuracy and key recognition.
• Non-clicky and non-silent, so it produces moderate sound without sharp clicks, suitable for shared workspaces.
• Bottom-out feel is firm due to a two-stage spring, providing a stronger return and clear key reset.

Actuation Characteristics

• Actuation force of 59g requires moderate finger pressure, balancing speed and precision.
• Pretravel of 2.0 mm allows relatively quick key registration, while total travel of 3.4 mm gives ample key depth.
• Force variance of 15 cN may result in slight inconsistency between keys, which some users may notice.

Build Quality

• Stem made of POM offers smooth sliding and durability.
• Housing combines polycarbonate top and nylon bottom, supporting LED diffusion and structural stability.
• Gold alloy contact points improve electrical reliability and reduce corrosion risk.
• Two-stage spring design enhances key return force compared to standard springs.
• Factory lubed, which reduces initial scratchiness and noise, though additional lubing can further improve smoothness.

Compatibility

• Plate mount design fits most standard mechanical keyboard plates.
• Five-pin configuration supports PCB mounting for secure installation.
• Compatible with SMD LEDs, enabling customizable backlighting options.

Trade-offs

• Moderate actuation force may cause fatigue during long typing sessions for users preferring lighter switches.
• Force variance could lead to uneven feel across a full keyboard.
• Not silent, so less ideal for very quiet environments.
• Unknown long-term durability beyond rated 80 million operations.
