A buckling spring keyboard is a specific type of mechanical keyboard that uses a unique mechanism to register keypresses. While most modern keyboards use rubber domes or standard mechanical switches, the buckling spring design relies on a physical coil spring that collapses, or “buckles,” under pressure. This design is famous for its distinct tactile feedback and a loud, crisp clicking sound that many typing enthusiasts prefer.
Originally popularized by IBM in the 1980s, these keyboards have maintained a dedicated following for decades. Even as technology has shifted toward thinner and quieter designs, the buckling spring remains a gold standard for heavy-duty typing and durability. In this guide, we will explore how these keyboards work, their history, and whether one is right for your home or office setup.
How the Buckling Spring Mechanism Works
The core of this keyboard is a small, coiled spring situated beneath each keycap. When you begin to press a key, the spring provides resistance, which creates a firm feel. As you continue to apply pressure, the spring reaches a point where it can no longer remain straight.
At this specific moment, the spring suddenly bends or “buckles” to the side. This collapse causes a small plastic hammer at the bottom of the spring to strike a capacitive or membrane contact. This contact sends the signal to your computer that the key has been pressed.
The “click” sound you hear happens exactly when the spring buckles and the hammer hits the sensor. This provides the user with immediate auditory and physical confirmation that the character has been typed. Because the registration happens at the same time as the click, users often find they make fewer typing errors.
The History of the IBM Model M
You cannot discuss buckling spring keyboards without mentioning the IBM Model M. Introduced in 1985, the Model M became the standard keyboard for many early personal computers. It was designed to be incredibly durable and to provide a typing experience that mimicked high-end typewriters of the era.
The Model M was built with a heavy steel backplate, making it much heavier and sturdier than the keyboards we use today. Many of these original keyboards are still in use forty years later. Their longevity is a testament to the simplicity and strength of the buckling spring design.
While IBM eventually stopped producing these keyboards, the technology did not disappear. A company called Unicomp purchased the rights and the original tooling to continue manufacturing buckling spring keyboards. Today, they remain the primary source for modern versions of this classic hardware.
Benefits of Using a Buckling Spring Keyboard
Many people choose buckling spring keyboards because they offer a level of feedback that modern keyboards lack. If you spend several hours a day typing, the physical characteristics of these switches can change your entire workflow.
- Unmatched Tactility: The physical snap of the spring provides a clear sensation in your fingertips. This helps you develop a rhythm and can increase typing speed over time.
- Durability: These keyboards are built to last for millions of keystrokes. They are often heavier and less likely to slide around on your desk during intense typing sessions.
- Reduced Errors: Because you can feel and hear exactly when a key registers, you are less likely to “bottom out” or accidentally press keys twice.
- Nostalgic Appeal: For many, the look and sound of a buckling spring keyboard bring back memories of early computing, providing a satisfying, retro aesthetic.
Potential Drawbacks to Consider
While these keyboards have many fans, they are not suitable for every environment or user. Before purchasing one, it is important to understand the practical challenges they might present in a modern setting.
The most significant factor is noise. Buckling spring keyboards are significantly louder than almost any other type of keyboard. The sharp “ping” and “click” of the springs can be distracting to coworkers in an open office or to family members in a shared living space.
Additionally, these keyboards require more force to press than modern laptop keys or “linear” mechanical switches. This can lead to finger fatigue if you are used to a very light touch. They are also quite large and heavy, which makes them difficult to transport or use in small workspaces.
Buckling Springs vs. Other Mechanical Switches
If you are looking at mechanical keyboards, you will likely see options like Cherry MX Blue or Brown switches. While these are also “clicky” or “tactile,” they function differently than a buckling spring. Modern switches use a plastic slider and a small metal leaf to create the click.
Buckling springs are generally considered to have a more “organic” feel because the entire spring is involved in the movement. Modern switches often feel more clinical or precise, whereas a buckling spring feels more mechanical and industrial. The sound profile is also different; buckling springs have a lower-pitched, metallic “clack” compared to the higher-pitched “click” of modern switches.
Where to Buy a Buckling Spring Keyboard Today
If you want to experience a buckling spring keyboard, you have three main options. Each path offers a different balance of price, convenience, and authenticity.
1. Buy New from Unicomp: As mentioned, Unicomp still produces the “New Model M” and the “Ultra Classic.” These use the original IBM designs but come with modern USB connections. This is the easiest way to get a brand-new keyboard with a warranty.
2. Purchase a Vintage IBM Model M: You can often find original IBM keyboards on auction sites or at electronics recyclers. While these are highly prized, they often require a specialized adapter to work with modern computers. You may also need to perform some basic cleaning or repairs.
3. High-End Recreations: Some boutique manufacturers, such as Model F Labs, produce extremely high-quality recreations of even older IBM designs. These are often made of solid zinc or aluminum and are significantly more expensive than standard keyboards.
How to Clean and Maintain Your Keyboard
Because these keyboards are built to last for decades, they occasionally need some maintenance. Keeping the mechanism free of dust and debris will ensure the springs continue to buckle smoothly.
To clean your keyboard, start by unplugging it from your computer. Most buckling spring keyboards allow you to easily remove the keycaps using a keycap puller tool. Once the caps are removed, you can use compressed air to blow out any crumbs or dust from the assembly.
If the keycaps are dirty, you can wash them in warm water with a small amount of dish soap. Ensure they are completely dry before snapping them back onto the springs. Avoid using harsh chemicals on the keyboard frame, as this can damage the plastic finish.
Is a Buckling Spring Keyboard Right for You?
Choosing a keyboard is a personal decision that depends on your typing style and your environment. A buckling spring keyboard is an excellent choice if you prioritize tactile feedback and durability above all else. It is a tool designed for writers, coders, and anyone who spends their day producing text.
However, if you work in a quiet office or prefer a minimalist, portable desk setup, you might find the size and noise level to be a hindrance. It is often helpful to listen to sound demonstrations online or try one in person before making the investment.
Ultimately, the buckling spring keyboard represents a piece of computing history that remains functional and relevant today. Its unique design offers a typing experience that many believe has never been surpassed by modern alternatives.
