📄 Product Description
The Kaidi KOS Switch Springs are made from high-quality Korean Stainless Steel (KOS), valued for its material purity, consistent spring force, and excellent corrosion resistance. With a length of 22 mm (long springs) and their single-stage profile, they produce an even, linear force curve across the entire travel – ideal for anyone who prefers a precise and clean switch feel.
Why Kaidi KOS Springs?
- Korean Stainless Steel: KOS steel offers top material quality, a clean surface, and consistent spring force – ensuring a stable typing feel for years without spring fatigue.
- Tight weight tolerances (±2 g): Perfect for enthusiasts who value reproducible results – whether you're lubing, filming, or fine-tuning your switch feel.
- Single-stage profile: Ideal for linear switches, but also a great choice for making tactile switches feel more precise and controlled. The force curve stays even and predictable from first press to bottom-out.
- 22 mm long springs: Deliver a balanced mix of soft initial travel, stable guidance, and quick return to the resting position.
- A weight for every setup: Available in 9 variants – from light (30 g) to heavy (77 g) – so you can dial in the typing feel exactly the way you want.
Weight Options
Available in the following bottom-out forces:
- Light: 30 g, 37 g, 42 g – for a feather-light, fast typing feel
- Medium: 45 g, 48 g, 53 g – the classic all-rounder range
- Heavy: 58 g, 64 g, 77 g – for more resistance, a defined bottom-out, and a more powerful keystroke
