In this article, we will delve into the world of IBM Model M switches, exploring their history, design, and functionality.
A Brief History of the IBM Model M
Before diving into the switches, it’s essential to understand the context in which the IBM Model M was created. The Model M was first introduced in 1984 by IBM, designed to be a more efficient and cost-effective alternative to the earlier IBM PC keyboard. The brainchild of Don Estridge and his team, the Model M was built to last, with a focus on durability and performance.
The Switches Behind the Model M
The IBM Model M uses a type of switch known as the buckling spring switch. This innovative design was patented by IBM in the early 1980s and has since become synonymous with the Model M.
How Buckling Spring Switches Work
Buckling spring switches operate on a simple yet ingenious principle. Each switch consists of a spring-loaded metal rod that is connected to a pivot point. When a key is pressed, the rod buckles, triggering an electrical contact that registers the keystroke. The spring then returns to its original position, ready for the next keystroke.
Key Characteristics of Buckling Spring Switches
Buckling spring switches have several distinct characteristics that contribute to their unique feel and sound:
- Tactile feedback: The buckling action provides a clear, tactile bump that lets the typist know when the switch has been activated.
- Audible click: The sound of the spring buckling is unmistakable, providing an audible confirmation of each keystroke.
- High actuation force: Buckling spring switches require a relatively high amount of force to activate, which can help reduce typos and improve typing accuracy.
Types of Buckling Spring Switches Used in the IBM Model M
While all IBM Model M keyboards use buckling spring switches, there are some variations in the specific types used. The most common types are:
- Heavy-duty buckling spring switches: These switches were used in the early Model M keyboards and are characterized by their heavy, tactile feel.
- Lighter buckling spring switches: Later Model M keyboards used lighter switches, which provided a slightly more delicate feel.
