With the Matias Quiet Linear switch, we've added a special internal leaf spring, that offsets the detrimental effects of Hooke's Law. It adds a little extra resistance at the beginning (when Hooke's Law's impact is small) that gradually decreases as the coiled spring's resistance increases. This gives you a smoother, more stable, linear feel than any other linear switch. Designed specifically for stenographers, the Matias Quiet Linear was designed to be ultra quiet and ultra light to the touch for silent, prolonged typing.
Actuation Force: 35g

The detachable cable uses a standard mini-USB connector.

Arriving in the standard tiered profile, it's equipped with little more than the essential keys. There’s no required software to install after plugging in through the USB interface, and a six-port DIP switch allows users to adjust the FN key position.
Warning : The keyboard should be unplugged while changing the DIP switch settings.
