IBM Model F Buckling Spring
ClickyThe Model M's older, better-built sibling (1981). Capacitive sensing instead of a membrane and a metal backplate give it a lighter touch and a ringing, higher-pitched ping-click collectors consider the finest buckling spring ever made.
Sound & feel
Before the cost-reduced Model M came the Model F, introduced with the original IBM PC in 1981. Its buckling springs actuate a capacitive PCB rather than a membrane, allowing a slightly lighter, crisper stroke, and its metal backplate turns every buckle into a ringing, musical "ping-click" that vintage collectors regard as the pinnacle of the mechanism.
Build quality is industrial to the point of absurdity: steel everywhere, keys rated far beyond any modern switch, boards that shrug off forty years of use. That durability is why working Model Fs still circulate, though clean examples now command serious collector prices.
A modern reproduction project (Model F Labs) machines new boards with the original mechanism for those unwilling to gamble on 1980s survivors. For feel-plus-sound purists, the Model F remains the buckling spring to beat.

Frequently asked questions
What does the IBM Model F Buckling Spring sound like?
higher-pitched ringing ping-click off a metal backplate. Use the player on this page to hear simulated press and release sounds derived from its real specifications.
Is the IBM Model F Buckling Spring good for gaming or typing?
Clicky switches like this are typing-first: the click is satisfying but loud for shared spaces and voice chat. For quiet environments, look at silent tactiles instead.
How heavy is the IBM Model F Buckling Spring?
62g actuation. Note that IBM officially rates actuation force. Brands differ, so check the basis when comparing switches.
