Buckling Springs

Buckling springs originated in IBM’s mechanical keyboard as a fundamentally different kind of switch mechanism. Featuring a coil spring that sits between the keycap and a pivoting hammer that collapses when clicked, the spring provides a loud, tactile feedback.

Model M-Inspired Keycaps

The buckling spring keycaps are made of PBT polymer. The dye-sublimated legends compliment the authentic feel and classic design, reminiscent of the original Model-M keycaps.
