What Are Buckling Spring Switches?

What Are Buckling Spring Switches?

Buckling Spring Switches are a type of mechanical switch that utilizes a distinctive spring-loaded mechanism. When a key is pressed, the spring beneath the keycap compresses until it “buckles” to one side, creating an audible and tactile feedback. This mechanism is renowned for its unique feel and sound, making it a favorite among typists who relish the classic typewriter-like experience.

These switches gained prominence during the 1980s and early 1990s, primarily found in IBM keyboards. While they have evolved over the years, their core design principles and appeal have remained remarkably consistent.

The Typist’s Delight

One of the defining characteristics of Buckling Spring Keyboards is their design with typists in mind. Unlike many modern keyboards optimized for gaming, Buckling Spring Switches are engineered to provide an exceptional typing experience. Typists appreciate the tactile feedback and audible click, which contribute to improved typing speed and accuracy.

Furthermore, the larger keycaps and key size provide a comfortable typing surface. Typing on a Buckling Spring Keyboard often feels like gliding over a smooth and responsive surface, making it an excellent choice for those who spend hours typing documents, reports, or code.

The Auditory Symphony

One cannot discuss Buckling Spring Switches without mentioning the iconic sound they produce. The audible click and clack of each keypress resonate with nostalgia for many users. Some describe it as a comforting white noise, while others find it invigorating, almost like a musical accompaniment to their typing endeavors.

The distinct sound of Buckling Spring Keyboards is not just auditory nostalgia; it serves as an auditory confirmation of each keystroke, providing valuable feedback for typists. The symphony of sound that accompanies each typing session is a testament to the unique charm of these switches.

The Historical Significance of Buckling Spring Keyboards

To truly appreciate the legacy of Buckling Spring Switches, it is essential to delve into their historical context and understand their role in shaping the keyboard industry. IBM, a technological powerhouse in the 20th century, played a pivotal role in introducing and popularizing these switches.

The Inventor: Richard Hunter Harris

The story of Buckling Spring Switches begins with Richard Hunter Harris, the brilliant inventor behind this iconic mechanism. In 1977, Harris patented what he aptly named the “catastrophic buckling compression column switch and actuator.” This mouthful of a name encapsulated the essence of the mechanism that would revolutionize typing.

The term “Buckling Spring” itself was derived from the way the spring underneath the keycap compressed and buckled when a key was pressed. It was a eureka moment that would forever change the keyboard landscape.

IBM Model M: The Legend Takes Shape

IBM Model M

In 1984, IBM introduced the world to the IBM Model M keyboard. This moment marked the zenith of Buckling Spring Keyboards’ popularity and cemented their status as a classic among keyboard enthusiasts. The Model M was an instant hit, celebrated for its tactile feel, robust build quality, and distinctive sound.

Over the years, the Model M underwent minimal changes, a testament to its timeless design. Typists cherished it not only for its exceptional typing experience but also for its durability. The Model M was built to withstand the test of time, and many of these keyboards continue to function flawlessly decades after their initial release.

Transition and Transformation

In 1994, IBM transitioned the production of Buckling Spring Keyboards to Lexmark. While the essential Buckling Spring Switch mechanism remained unchanged, Lexmark introduced some alterations to reduce manufacturing costs. These changes included using a single color for keycaps, adopting lightweight plastic shells, and streamlining the keyboard’s design.

Despite these modifications, the core typing experience of Buckling Spring Keyboards remained intact. Typists continued to appreciate the familiar tactile feedback and audible click that set these keyboards apart.

How Do Buckling Spring Keyboards Work?

How Do Buckling Spring Keyboards Work?

Understanding the inner workings of Buckling Spring Keyboards provides insight into what makes them so beloved by typists. The operation of these keyboards relies on a simple yet ingenious mechanism:

  1. Spring Compression: When a key is pressed, the spring beneath the keycap begins to compress.
  2. Buckling Action: As pressure on the spring increases, it eventually reaches a point where it buckles or bends to one side.
  3. Keystroke Registration: The buckling action of the spring causes the keycap to press down on a set of membranes, closing an electrical circuit and registering a keystroke.

The keycaps on Buckling Spring Keyboards are notably larger than those on contemporary keyboards, requiring a firmer keypress to register. This design choice aligns with the typist-centric approach of these keyboards, providing a comfortable and satisfying typing experience.

What Is the Typing Experience Like?

To truly appreciate Buckling Spring Keyboards, it’s essential to consider the tactile and sensory aspects of typing on these mechanical wonders. Users’ experiences with Buckling Spring Keyboards vary, with some common themes:

Machine-Like Precision

Typing on a Buckling Spring Keyboard often evokes a sense of machine-like precision. The tactile bump and audible click provide feedback with each keystroke, giving typists a clear sense of key activation. This precision is especially valuable for typists who require accuracy in their work.

Engaging Sound

The distinct sound of Buckling Spring Keyboards is an integral part of the typing experience. Some users describe it as a symphony of sound, with each keypress contributing to the overall rhythm. For many, this auditory feedback adds an element of satisfaction to their typing sessions.

Key Weight and Comfort

Buckling Spring Keyboards typically feature a key weight of approximately 70 grams, striking a balance between ease of typing and tactile feedback. Typists find this weight comfortable, as it requires just enough force to register a keystroke without feeling too heavy or fatiguing.

However, individual preferences vary, and some typists may prefer lighter or heavier switches, making Buckling Spring Keyboards an excellent choice for those seeking a specific typing feel.

Varied Opinions

As with any keyboard switch, opinions about Buckling Spring Keyboards are diverse. Some users relish the classic feel and sound, finding it an irreplaceable part of their daily routine. Others, particularly gamers, may find the switches less suitable due to their heavy actuation force and the noise they generate during rapid keypresses.

Additionally, Buckling Spring Keyboards typically support only 2-key rollover, which means they may not meet the requirements of gamers who demand simultaneous keypress recognition for complex in-game actions.

The Continuing Legacy of Buckling Spring Keyboards

While many keyboard technologies have come and gone, Buckling Spring Keyboards have defied obsolescence. Their enduring appeal is a testament to the unique typing experience they offer. Keyboards featuring these switches have remained in production, allowing enthusiasts to relish the nostalgia and functionality of Buckling Spring Switches.


In 1996, Unicomp Corporation, based in Kentucky, took up the mantle of producing and preserving Buckling Spring Keyboards. Unicomp’s commitment to upholding the legacy of these switches has kept them accessible to aficionados and newcomers alike.

Unicomp offers an array of Buckling Spring Keyboards, including models that faithfully replicate the design of the IBM Model M. They also provide customization options, allowing users to choose keycap colors and layouts that suit their preferences.
