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

In this review the DUROCK Ice King Linear Switches are evaluated for builders and typists who prioritize a smooth, clear-sounding linear feel and wide RGB compatibility. The bottom line: these switches excel when you want a low-wobble, full-transparent housing and stem with a deliberate 62g progressive bottom out, producing a deeper, marble-like sound and bright lighting. They arrive factory pre-lubed in a 90-piece jar and are aimed at custom keyboard enthusiasts seeking consistent feel and optimized acoustics.

Key Features

• Full transparent construction: The polymer nylon housings and modified transparent polyamide stem provide excellent light transmission for vivid SMD or through-hole LEDs.
• Long progressive spring: The 62g bottom out progressive spring gives a satisfying deeper sound and a controlled, steady bottoming feel compared with lighter linear springs.
• Minimal wobble: High-precision molds and tight tolerances reduce housing and stem wobble for a sturdier typing feel.
• Factory pre-lubed: Switches arrive lubed from the factory, delivering smoother travel out of the jar and reducing the need for immediate modification.
• Durable contacts: Gold contacts and rated for 60 million operations ensure long-term electrical reliability.
• Hot-swap ready: Two thick metal pins and PCB-mount design make these compatible with many hot-swap and soldered boards.

Who It's For

The Ice King switches suit custom keyboard builders and gamers who want a linear switch with a heavier, progressive bottom out and clear housings for pronounced RGB lighting. They are especially attractive to users who value sound tuning, as the longer pole stem creates a deeper, marble-like tone that customers often praise.

Less suitable for those who prefer tactile feedback or very light actuation, or for users who want a near-silent, cushion-bottoming experience; the 62g progressive spring and deeper sound are intentional characteristics that may not fit every typing preference.

Pros & Cons

Pros

• Clear housings and removable light column deliver strong brightness and clarity for RGB setups.
• Factory lubing and precision molds yield a smooth, low-wobble feel straight from the jar.
• Durable gold contacts and 60 million operation rating provide long-term reliability.
• Deeper, pleasing acoustic profile noted by multiple customers, often described as marble-like.

Cons

• The 62g progressive bottom out is heavier than some linear preferences and may feel too firm for light typists.
• Pre-lubed finish limits those who prefer to fully customize lube application without cleaning first.
