Gasket in Keyboards: A Complete Walkthrough
Gasket in Keyboards: A Complete Walkthrough

Keyboards are like secret gardens, hiding small wonders behind every key press. Have you ever wondered what makes your keyboard feel so smooth and responsive? Well, there's a tiny but mighty component called a gasket that plays a big role in that. Whether you're a seasoned keyboard enthusiast or just diving into the world of mechanical keyboards, understanding gaskets can enhance your typing experience. In this blog, we're going to take a complete walkthrough of gaskets in keyboards, explaining what they are, how they work, and why they matter.

What's a Gasket in Keyboards?

Let's start with the basics. Imagine your keyboard as a sandwich. You've got the top layer, which is where all the keys are, the bottom layer, which is the base, and in between, you've got the filling – that's where the gasket comes in.

A gasket is like a soft, squishy material placed between the layers of a keyboard. They're typically made of soft materials like rubber or silicone. These materials serve as a buffer between different parts of the keyboard, helping to reduce vibrations, and noise while also providing a more consistent typing feel. Think of it as the shock absorber in your car but for your keyboard.

How Do Keyboard Gaskets Work?

Okay, let's get a bit technical, but don't worry, we'll keep it simple! When you press a key on your keyboard, the force you apply gets transferred through the keycap and onto a mechanism called a switch. The switch is what registers your keypress and sends the signal to your computer. But without a gasket, all that force would go straight through to the base of the keyboard, making it feel stiff and uncomfortable.

A typical keyboard has several layers. There's the top plate, which is where the keys are located, the bottom plate, which holds the switches, and the case, which is the outer shell of the keyboard.

The gasket sits between the top and bottom layers of the keyboard, acting as a buffer. When you press down on a key, the force is transmitted through the keycap, down to the switch, and then to the bottom plate. Without a gasket, this force can make the keyboard feel stiff and uncomfortable. But with a gasket in place, it absorbs some of the force and spreads it out evenly. This not only makes typing more comfortable but also reduces the noise and makes the keyboard feel more responsive.

Think about it like this: imagine you're jumping on a trampoline. If the trampoline had no springs (kind of like a keyboard without a gasket), you'd hit the ground hard and it wouldn't be much fun. But with springs (like a keyboard with a gasket), you bounce up and down softly, feeling comfortable and bouncy!

Types of Gaskets in Keyboards

There are various types of gaskets used in keyboards, each with its unique characteristics. Here are some common ones:

1. Silicone Gaskets

These are soft and flexible gaskets made from silicone material. They're popular for their ability to absorb vibrations and dampen sound, resulting in a quieter typing experience.

2. Foam Gaskets

Foam gaskets, often made of materials like neoprene or poron, offer a slightly firmer typing feel compared to silicone. They still provide good vibration dampening but may also help with sound dampening, making your keyboard quieter.

3. Rubber Gaskets

Rubber gaskets are commonly used in keyboards for their affordability and ease of manufacturing. While they may not provide as much cushioning as silicone or Poron gaskets, they still offer decent sound dampening and vibration reduction.

Benefits of Gaskets in Keyboards

So, why bother with gaskets in keyboards? Here are some benefits:

1. Improved Typing Feel

Gaskets help create a more uniform typing feel by reducing inconsistencies caused by plate flex and case resonance.

2. Quieter Typing

By absorbing vibrations and dampening sound, gaskets can make your keyboard quieter, which is especially useful in shared or quiet environments.

3. Customization

Gasket mounting systems allow for easy customization and tuning of the typing experience. You can experiment with different gasket materials and configurations to find the perfect feel for your typing style.

4. Reduced Fatigue

The cushioning effect of gaskets can help reduce typing fatigue, allowing you to type for longer periods comfortably.

Gasket Mounting Systems

Now, let's talk about how gaskets are integrated into keyboards. One popular method is through gasket mounting systems. A gasket mounting system is a way of putting together the different parts of a keyboard to make it work smoothly. It's like building a sandwich – you've got the bread (which is like the base and the top plate of the keyboard), and then you've got the filling (which is the gasket). These systems use gaskets to suspend the keyboard's plate and PCB (printed circuit board) within the case, creating a cushioned barrier between the components.

Gasket mounting systems come in various configurations, including top mount, tray mount, and sandwich mount. Each has its pros and cons, but they all aim to enhance the typing experience by isolating the plate and PCB from the case, reducing vibrations, and improving sound quality.

Types of Gasket Mounting Systems in Keyboards

There are different types of gasket mounting systems used in keyboards, each with its unique properties and feel.

1. Top Mount

In a top mount keyboard, the gasket sits between the top plate (the layer where the keys are) and the case (the outer shell of the keyboard). This type of mounting provides a soft, cushiony feel and is often preferred by people who like a more tactile typing experience.

2. Bottom Mount

Here, the gasket is placed between the bottom plate (the layer where the switches are mounted) and the case. Bottom-mount keyboards tend to feel more rigid compared to a top mount, but they still offer some degree of cushioning and vibration reduction.

3. Integrated Plate

In keyboards with an integrated plate, the gasket is integrated into the design of the plate itself. This can provide a more seamless and consistent typing experience, as the gasket is directly attached to the plate.

Gasket Modding: The Next Level

Now, if you're really serious about mechanical keyboards, you might want to try your hand at gasket modding. This involves replacing the stock gaskets in your keyboard with aftermarket ones or even making your own.

Gasket modding can be a fun and rewarding hobby, but it's not for the faint of heart. Patience, precision, and a willingness to experiment are necessary. But for those who are willing to put in the effort, the results can be truly amazing.


In conclusion, gaskets play a crucial role in the feel and performance of your keyboard. By providing cushioning, shock absorption, and sound dampening, they enhance the typing experience and make it more enjoyable. Whether you're a casual user or a die-hard enthusiast, understanding the importance of gaskets can help you appreciate the craftsmanship that goes into making a great keyboard.
