KN 19

THE MEMBRANE-COVERED POWER SWITCH

The KN 19 is unique. The short-travel mains switch can safely switch 250 V with an operating stroke of only 0.55 mm. This means it can be used in membrane-covered flat input entry systems. So no perforation of the membrane or PCB is necessary for the power switch and the KN 19 can be conveniently integrated in the design of the front membrane. As a result of the standard overall height of 9.7 mm, the mains switch can be combined with other RAFI short-travel keyswitches and electronic components on a shared PCB.
