  • Publication number: 20170353182
    Abstract: An input device includes a first component with an actuating layer and a first electrode arranged adjacent thereto, a second component with a carrier and a second electrode, and a device which electrically contacts the first and second electrodes. The first and second electrodes face each other with an air gap therebetween. The first electrode, under an influence of an actuating force acting on the actuating surface undergoes, upon an actuation, a displacement so as to move the first electrode closer to the second electrode against an elastic restoring force. A detection and evaluation device applies a measuring capacitance to the first and second electrodes and detects a change in the measuring capacitance dependent on the displacement moving the first and second electrodes closer to each other in order to associate the actuation with a switching or controlling function after detecting a predetermined change in the measuring capacitance.
