When special types of glass are used, capacitive input devices are especially resistant against acids, dirt and other impurities. During their working life, the contacts do not suffer any mechanical abrasion. Cleaning the surface is easy and ensures maximum standards of hygiene. As the keypad surface is smooth, even a light touch results in comfortable and pressure-free operation. If required, a visual and/or acoustic signal can compensate for the lack of feedback.
The technology makes a flat design possible, and can be used behind glass, plastic or other non-conductive surfaces. It is especially suitable for robust input devices which are subjected to high mechanical loads. Customer-specific key designs can be manufactured at any time.
