Spring Applications

Compression springs used in a computer keyboard are also called buckling springs. There are many applications of springs; we will start with one application that curious customers ask about from time to time the computer keyboard. Compression springs used in a computer keyboard are also called buckling springs. The name refers to the fact that the coil spring tensed between the keycap and a pivoting hammer buckles, i.e. kinks or collapses, at a certain point in its downward traverse, providing auditory and tactile feedback to the keyboard operator. Upon buckling, the hammer is pivoted forward by the spring and strikes an electrical contact which registers the key press. In a Model M, the electrical contact is a membrane sheet similar to that of a modern dome switch keyboard. On the older Model F design, a capacitive contact was used instead. We will cover other spring applications that are commonly asked about in further blogs.
