- Buckling Spring switches
- Model M Dye Sub PBT keycaps
The Ultra Classic is a fantastic keyboard. It's built with the same buckling spring mechanisms, keybuttons, and steel baseplate as used on the Classic. The stair stepped keys, tactile, clicky feel, and robust design are the same as well.
It's Ultra because it uses a newly designed clamshell cover set reducing the footprint by 20% and eliminating almost half a pound of plastic.
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.
