Know before you buy
No, these springs are specifically engineered for the unique internal structure of Kailh BOX switches. They will not fit or function correctly in standard Cherry MX-style switches.
A standard linear switch typically bottoms out between 60g and 70g. At 125g, these springs provide a significantly heavier, more deliberate typing experience that is ideal for users who prefer high resistance to prevent accidental key presses.
Yes, changing the spring weight can subtly alter the acoustic profile of your switches. Because these are made of premium stainless steel and require more force to actuate, you may notice a deeper, more solid sound signature upon bottoming out.
You will need a switch opener compatible with Kailh BOX switches and a pair of precision tweezers to safely remove and replace the springs. It is also recommended to have a clean workspace, as the internal components of these switches are small and easily misplaced.
SPRiT springs are known for their consistent manufacturing tolerances and high-quality stainless steel construction. They offer a more uniform bounciness and a more predictable tactile feel compared to the standard springs included with stock Kailh BOX switches.
