ACTIVATION DEVICE FOR A MOTOR VEHICLE
First Claim
1. Activation device for actuation of a vehicle function, comprising a cover element, a light-distribution device arranged under the cover element, a light source arranged under or in the light-distribution device, wherein the light source and the light-distribution device are arranged for backlighting the cover element, wherein the cover element comprises an outward directed operation area at least partially formed of an electrically conductive metallic material, wherein the operation area is galvanically decoupled from the remaining components,wherein a circuit board is arranged under the light-distribution device with a capacitive sensor in such a manner that the capacitive sensor is capacitively coupled with the operation area,wherein the control and evaluation circuit is coupled with the light source and the proximity sensor to control the light source depending on an approach.

Abstract
An activation device for actuation of a vehicle function includes a cover element, a light distribution device arranged under the cover element, and a light source arranged under or in the light distribution device. The light source and the light distribution device are arranged for backlighting the cover element. The cover element includes an outward directed operation area at least partially formed of an electrically-conductive metallic material with the operation area being galvanically decoupled from the remaining components. A circuit board is arranged under the light distribution device with a capacitive sensor such that the capacitive sensor is coupled to the operation area. The control and evaluation circuit is coupled to the light source and the proximity sensor to control the light source depending on an approach.
