Keyboard O-Rings FAQs

What are O-Ring keyboard switch dampeners?

O-Ring dampeners are small rings made from rubber or silicone that are placed on the stems of mechanical keyboard switches to reduce noise and change the feel of the keystroke.

How do I install O-Rings on my keyboard?

You need to remove the keycaps, place an O-Ring on the stem of each switch, and then reattach the keycaps.

Do they reduce the sound of all keyboards?

They primarily reduce the sound of the key bottoming out, but won’t significantly alter the sound of the switch mechanism itself.

Their lifespan varies depending on usage and material, but they typically last for several years.

Can I use O-Rings on backlit keyboards?
