Abstract
The invention relates to an operating device for a motor vehicle having a movable activation element for activating at least one switch element for generating a switch signal. The operating device comprises a sensor face which is arranged on the activation element and an optical reflection sensor device, which has at least one light emitting diode and at least one photodiode for optical radiation. A signal can be generated when the sensor face is approached and/or the sensor face is touched, in particular by means of a finger of a user.
Claims10
An operating device comprising a movable activation element for activating at least one switch element for generating a switch signal, a sensor face and an optical reflection sensor device that has at least one light emitting diode and at least one photodiode for optical radiation, wherein a signal is generated when the sensor face is approached or touched by a user, and wherein the sensor face is arranged on the activation element, wherein the sensor face is configured as a label made of a first plastic layer which transmits light, and a second layer which does not transmit light and transmits infrared radiation, and wherein the label is manufactured as a two-component part.
An operating device comprising a sensor face and an optical reflection sensor device that has at least one light emitting diode and at least one photodiode for optical radiation, wherein a signal is generated when the sensor face is approached or touched by a user, wherein the optical radiation has a wavelength which is not in the range of the light which is visible to the human eye,
- wherein the sensor face is configured as a label made of a first layer which is transparent to visible light and a second layer which is transparent to the optical radiation and nontransparent to visible light, and wherein the optical radiation is infrared radiation.
