Membrane Keypads with Night Design

The back-lit Profiline keypad is constructed in a similar way to a normal Profiline keypad. The basic difference is the basis membrane, which is made with an FR4 PCB. An LED is mounted on this PCB on the rear in the middle of the key. The back-lit Profiline keypad has additional advantages such as its long operating life, low power consumption and haptic feedback. This technology makes it possible to illuminate the keys separately – the light passes through a hole in the special snap dome into the integrated acrylic inlay, where it is scattered accordingly. The easy-to-feel key element makes it much easier to use.
