DUROCK Ice King Linear Switches 62g Progressive Spring - Smooth RGB

Our review of the DUROCK Ice King Linear Switches finds them well suited to builders who want a smooth, clear-sounding linear switch with wide RGB compatibility. The single biggest reason to buy is the combination of full transparent housings and a long progressive 62g spring that deliver a deeper, controlled bottom-out feel and excellent light transmission for both SMD and through hole LEDs. These switches are factory pre-lubed and built from precision molds, so they offer a reduced wobble and a tactile-free linear travel for both custom keyboards and hotswap builds.

Key Features

• Full transparent materials: The clear polymer nylon housing and modified polyamide stem let LEDs shine through cleanly for bright, crisp RGB illumination.
• 62g progressive spring: The longer, gold plated progressive spring gives a deeper, controlled bottom-out and a distinct feel compared with shorter springs.
• Precision molds: Same high-precision tooling lineage as higher-end DUROCK switches, which reduces housing and stem wobble for a more consistent press.
• Factory pre-lubed: Out of the jar the switches feel smooth and show minimal scratchy noise, saving time during a build.
• Wide lighting and PCB compatibility: Removable light column plus SMD and THT friendly design works with most hotswap or soldered PCBs and LED types.
• Durable contacts: Gold contacts and rated over 60 million operations for long-term reliability.

Who It's For

The Ice King linear switches suit keyboard enthusiasts who prioritize sound and lighting. Builders aiming for a clear, bright RGB effect will appreciate the full transparent housings and removable light column, while typists and gamers who like a heavier, progressive bottom-out will value the 62g spring and reduced wobble.

These are less appropriate for people seeking a tactile bump or very light actuation; if you prefer ultra-light linear springs or a distinct tactile profile, look at lighter or tactile-specific switches instead.

Pros & Cons

Pros

• Excellent light clarity and brightness from full transparent housing and removable light column.
• Smooth, low-wobble feel thanks to precision molds and modified polyamide stems.
• Deeper, satisfying bottom-out feel from the long progressive 62g spring and gold plated spring design.
• Factory pre-lubed condition lets builders use them immediately without heavy initial tuning.

Cons

• Heavier bottom-out may not suit users who prefer very light actuation or a tactile bump.
• Full transparency can reveal internal lubricant on some switches, which may concern aesthetic purists.
