General data

The KN 19 makes it possible to implement a power switch directly in a low-profile data entry system. This eliminates the

need for extra switches on the device and additional openings in the overlay. In this way, you can achieve an optimum of

safety and a consistent design.

The contact opening widths comply with the VDE standards. The KN 19 can also be employed underneath RK 90 keycaps.

Other actuation functions (momentary, latching/momentary) available on request.
