<p>The device (10) has a homogenous actuating surface (10a) forming a visible side of the device, where the visible side is designed as a continuous, uninterrupted surface. A symbol is represented on the actuating surface. A signal is outputted by the device to an electrical component, which is associated to the symbol, by contacting regions (10b) of the actuating surface with an actuating element. A glass panel (11) is formed from sapphire glass. The glass panel has a thickness of 3 mm. The actuating surface is sectionally provided with a nano coating (12).</p> |
