Mechanical switches Ducky DSK110-FPA2 Kailh Y Jellyfish 5-pin linear 50g

Ducky DSK110-FPA2 mechanical switches are Kailh Y Jellyfish linear switches with a 5-pin configuration and a 50g actuation force, designed for use in mechanical keyboard builds. These switches offer consistent, smooth linear travel without tactile bumps or audible click, providing predictable keystrokes suitable for both gaming and typing. The 5-pin housing ensures secure PCB or plate mounting and broad compatibility with modern mechanical keyboard layouts that support plate-mounted or PCB-mounted switches.

Advantages

The Kailh Y Jellyfish linear design delivers low-resistance, uniform key travel that reduces finger fatigue during extended use. A 50g actuation force balances responsiveness and stability, giving clear feedback through consistent keystrokes without tactile interruptions. The 5-pin configuration improves mechanical stability in the switch housing, reducing wobble and enhancing switch alignment on plates and PCBs. The switches are built to industry standards for mechanical keyboard compatibility, allowing straightforward installation in custom builds and many prebuilt boards that accept 5-pin switches.

Suitable for

• Gaming where smooth, rapid keypresses and consistent actuation are preferred
• Typing tasks that benefit from linear travel and reduced tactile interference
• Custom mechanical keyboard builds requiring 5-pin switch mounting
• Users seeking a balance between light and firm actuation at 50g

Key specifications

• Switch type: linear
• Actuation force: 50 grams
• Pin count: 5-pin configuration for plate or PCB mounting
• Actuation characteristic: smooth travel without tactile bump or click
• Intended device: mechanical keyboards

How to use

Install the Ducky Kailh Y Jellyfish 5-pin switches by aligning the five pins with the holes in the PCB or plate, ensuring the switch stem faces the correct orientation for keycaps and stabilizers. Press the switch body firmly into the mounting position until fully seated. If soldering to a PCB, solder each pin following standard keyboard assembly practices and safety guidelines. After installation, fit compatible keycaps onto the stems and test each key to confirm stable, even travel and correct actuation.

Usage recommendations

For optimal performance, pair these linear 50g switches with medium-profile keycaps and proper stabilizers on larger keys. If you experience minor wobble, verify plate alignment and consider using thinner lubing on the slider for smoother operation. Use appropriate soldering equipment and ESD precautions during assembly.
