Switch Dampening O-rings are attached to the stems of Cherry MX style keycaps in order to prevent the bottoming out the switches when fully-pressed.

This can make for a much quieter typing experience and increase shock-absorption, resulting in more comfort and less finger-fatigue.

Blue O-Rings are thicker and denser than their Red counterparts and reduce travel further.


  • Set of 125 pcs.
  • (Blue) 0.4mm travel reduction. Softer landing for better shock absorption.
  • Reduces sound level produced by the key
  • Shock absorption minimises finger fatigue
  • EPDM rubber, resistant to cracking and tearing

Buying from CoderKit

You could buy this anywhere but we really want you to buy it from us. Here's some reasons why we think you should:

  1. Happiness++ Guarantee - If you don't like how it codes, give it back and we'll get you something you do like. Read more.
  2. Stocked locally - That mean's it's real, in country and ready to ship to you. Unless it says out of stock. In which case we're still waiting for it to come in.
  3. Curated selection - If you are seeing it here, it's because we've tried it out and we think it's fit for coding.
