The latest generation of pushbuttons and switches is located behind a protective glass panel. That makes them suitable for industrial and many other applications. Even after millions of operations, our GLASSCAPE sensor continues to work faultlessly. Mechanical systems or resistive touch technology don't even come close to these results. Furthermore, the hygienic surface, stylish good looks, and elegant illumination make operation a pleasure.

We offer a wide variety of individually-developed capacitive sensors to facilitate your human-machine communication. You can combine them to achieve your own operational landscape. Applying different glass treatments, we achieve optimum haptics for any operating element.


Powerful LED elements light up the glass surface in rich colors. To make operation easier, light signals can guide users. Also available for input feedback are visual and acoustic signals. If a button is currently inactive, the system can turn off the illumination so the key disappears. This effect makes operation easier and simultaneously improves the appearance.


We design operating landscapes consisting of illuminated capacitive pushbuttons with extremely low mounting depths. Generally, we use copper-coated circuit boards for sensors. This is how we can install RAFI control systems in very tight spaces. There is a narrow light conductor for the illumination between the printed glass front and the sensor. The sensor is mechanically connected to the front glass, eliminating the need for optical lamination.
