Mechanical keyboards have gained immense popularity among computer enthusiasts, gamers, and typists due to their superior tactile feedback and durability. Among the various components that contribute to their outstanding performance, O-rings play a crucial role. In this comprehensive guide, we will delve into the essential function of O-rings on a mechanical keyboard and explore their benefits, types, installation, and maintenance. Whether you are a seasoned mechanical keyboard user or a beginner, this article aims to provide you with valuable insights and expert advice on making the most of O-rings for an enhanced typing experience.

What function about O-Rings on a Mechanical Keyboard?

O-Rings are small rubber rings that are strategically placed under the keycaps of a mechanical keyboard. Their primary function is to dampen the impact of key presses, thereby reducing the noise and reverberation that occurs when a key is bottomed out during typing. When you press a key on a mechanical keyboard without an O-ring, it hits the keyboard's PCB or plate with an audible and tactile thock. However, with O-rings in place, the rubber acts as a cushion, absorbing the impact and creating a softer landing for the keycap.

The result is a quieter typing experience that is particularly useful in shared environments or quiet workspaces. Additionally, O-rings help prevent the key from "bottoming out" completely, reducing the distance a key needs to travel to register a keystroke. This reduced travel distance can lead to faster typing speeds and less finger fatigue over extended typing sessions.

Benefits of Using O-Rings on a Mechanical Keyboard:

  1. Noise Reduction: One of the most significant advantages of using O-rings is the substantial reduction in typing noise. The rubber dampens the sound of each keystroke, making it ideal for office settings or late-night typing sessions where silence is essential.
  2. Tactile Feedback Preservation: While O-rings soften the impact of key presses, they do not compromise the tactile feedback of mechanical switches. Typists can still enjoy the satisfying feel of the switches without the excessive noise.
  3. Faster Typing Speeds: As O-rings reduce the distance keys need to travel to register, typists can achieve faster typing speeds and increased efficiency.
  4. Less Fatigue: With a softer landing for each keystroke, O-rings help reduce finger fatigue during prolonged typing sessions, making them a favourite among writers and programmers.
  5. Extended Keycap Lifespan: O-rings protect keycaps from hard impacts, leading to a longer lifespan for your precious keycaps.
  6. Customization Options: O-rings are available in various thicknesses, providing users with the flexibility to choose the level of cushioning that suits their preferences.

Types of O-Rings for Mechanical Keyboards:

There are two primary types of O-rings used with mechanical keyboards:

1. Soft Landing O-Rings:

Soft landing O-rings, also known as dampeners, are the most common type used for mechanical keyboards. They are made from soft rubber materials and provide a gentle cushioning effect when a key is pressed. These O-rings are ideal for users looking to reduce typing noise without compromising the tactile feel of their keyboard switches. Soft landing O-rings come in different thicknesses, typically ranging from 0.2mm to 0.4mm, allowing users to fine-tune the level of noise reduction and key travel distance.

2. Silent O-Rings:

Silent O-rings, as the name suggests, are designed explicitly for noise reduction. They are made from premium quality materials that effectively dampen the sound of keystrokes, resulting in an almost silent typing experience. Silent O-rings are thicker than soft landing O-rings, usually measuring around 0.5mm to 0.8mm. While they offer enhanced noise reduction, they may slightly affect the tactile feedback of some mechanical switches.

Installing O-Rings on Your Mechanical Keyboard:

Installing O-rings on your mechanical keyboard is a straightforward process that requires basic tools and a bit of patience. Here's a step-by-step guide to help you with the installation:

  1. Gather Your Materials: Before you begin, ensure you have the O-rings of your choice, a keycap puller, and a clean, flat surface to work on.
  2. Remove Keycaps: Carefully remove the keycaps from your keyboard using the keycap puller. Gently wiggle the puller to lift the keycaps without damaging them.
  3. Place O-rings: Take an O-ring and place it around the stem of the switch. Ensure it sits evenly without being misaligned.
  4. Reattach Keycaps: After placing the O-rings on the switches, reattach the keycaps by pressing them down firmly until they click into place.
  5. Test the Keyboard: Once all keycaps are back in place, test your keyboard to ensure that the O-rings have been installed correctly. Type a few sentences to gauge the noise reduction and typing feel.

Maintaining Your O-Rings and Mechanical Keyboard:

Proper maintenance is crucial to ensure the longevity and optimal performance of your mechanical keyboard with O-rings. Here are some essential maintenance tips:

  1. Regular Cleaning: Dust and debris can accumulate over time, affecting the performance of both the switches and O-rings. Regularly clean your keyboard using compressed air or a soft brush to keep it free from particles.
  2. Inspect O-rings: Periodically check the condition of your O-rings for signs of wear or damage. If any O-ring appears cracked or misshapen, replace it promptly to maintain the desired typing experience.
  3. Avoid Liquid Spills: Liquid spills can be detrimental to both the switches and O-rings. Be cautious when using liquids around your keyboard and clean up spills immediately.
  4. Keycap Care: Take care when removing or reattaching keycaps to prevent damage to the switches or O-rings. Use a keycap puller gently and avoid using excessive force.
  5. Store in a Safe Place: When not in use, store your mechanical keyboard in a dry and dust-free environment to prevent damage.

Frequently Asked Questions (FAQs)

Q: Do O-rings work with all mechanical keyboards? 

A: Yes, O-rings are compatible with most mechanical keyboards that have Cherry MX-style switches or similar clones.

Q: Will using O-rings affect the warranty of my mechanical keyboard? 

A: In general, using O-rings does not void the warranty of your mechanical keyboard. However, it's always best to check with the manufacturer to be certain.

Q: Can O-rings fix a keyboard with overly sensitive keys? 

A: Yes, using thicker O-rings can help reduce the sensitivity of keys, preventing accidental keystrokes.

Q: Do O-rings change the actuation point of switches? 

A: O-rings do not alter the actuation point of switches; they only reduce the key travel distance required for a keypress to be registered.

Q: Are O-rings difficult to install? 

A: Installing O-rings is a straightforward process and can be done by most users. However, if you are unsure, consider seeking assistance from a professional.

Q: Can I reuse O-rings if I change my keycaps? 

A: Yes, O-rings can be reused when changing keycaps, as long as they are in good condition and free from damage.


In conclusion, O-rings play a vital role in enhancing the overall typing experience on a mechanical keyboard. Their ability to reduce noise, preserve tactile feedback, and lessen finger fatigue makes them a popular choice among mechanical keyboard enthusiasts. When choosing O-rings, consider the thickness and material that best suits your preferences and typing style. With proper installation and maintenance, O-rings can significantly contribute to a more enjoyable and efficient typing experience. So, why not upgrade your mechanical keyboard with O-rings and level up your typing game?
