Keycap O-Ring Dampeners for Mechanical Keyboards - Introduction

Product Knowledge-base

Thanks for looking. Here is a basic intro to help you understand what Keycap O-Rings Dampeners do for your mechanical keyboard.

Basic intro: Your mechanical keyboard, regardless of brand uses some type of mechaincal switch. These switches vary greatly on sound, travel, resistance and overall feel. For example Corsair uses Cherry Switches. Logitech uses Romer G Switches. And although you might like it Team Green, even your Razer uses Cherry Switches (made in house by Cherry in Germany). ALl that matters is your experience and personal preference.

I personally use a Corsair K95 RGB with Cherry Red Silent switches.

Now the noise (loud) noise you tend to hear is your switch bottoming out. Bottoming out is when a key stroke is pressed all the way down where the stem of the switch hits the inside of the switch casing. Esentically you’re causing the switch to buckle. Its designed to, dont worry. Though your key press is already registered before the buckling occurs.

So where do these O-Rings come into play and why do you care?

Keycap O-Rings help do multiple things based on your selection. Some of the more common considerations are as follows.

  • Reduces key press travel from 0.2MM - 0.4MM

  • Reduces noise from preventing buckling of the switch

  • Allows for a bounce back effect due to the natural response of the O-Ring Material Type (Rubber/Silicone).

Other things to consider the the thickness, hardness and o-ring material. The two most common types are NBR (Nitrile Rubber) which is naturally black in color. The other is VMQ which is a Silicone Polymer. VMQ can be clear (opaque) or colored (Red, Green, Blue).

The thickness will determine travel reduction. Typically either 0.02MM or 0.04MM reduction. At 0.04MM, that is around a 50% reduction in travel.

Hardness is based on the Shore Hardness Rating (scale). You will typically see Shore Ratings on O-Rings between 40-80. More commonly 40-45 and 60-65. Meaning nearly all products will have a slightly varying percentage of hardness as a product cannot be produced that strict for such a cheap price.
