KN 19

THE MEMBRANE-COVERED MAINS SWITCH

The KN 19 is unique. It’s a tactile mains switch that can safely switch 250 V with an operating stroke of only 0.55 mm. This means it can be used in membrane-covered flat data entry systems. So the mains switch does not require any perforation of the membrane or PCB. As a result, you can easily integrate the KN 19 in the design of the front membrane. The standard overall height of 9.7 mm means you can combine the mains switch with other RAFI tactile switches and electronic components on a shared PCB.
