An input device, including a flat panel defining an array of control surfaces, and an array of capacitive sensors and a support. The control surfaces are on a surface of the panel facing towards the operator and the support is on a side of the panel facing away from an operator. Also, each capacitive sensor forms a measuring capacitance assigned to a control surface. Further, each capacitive sensor is formed by a common substantially flat film layer structure. The film layer structure includes a first electrode for forming the measuring capacitance. On the side of the support, a lighting device is provided for each control surface for backlighting the associated control surface and transmitting light through the film layer structure. Also, the input device reduces the passage of light from one capacitive sensor to an adjacent capacitive sensor.

Input device with an array of force sensors of a laminated construction with backlighting

A method of manufacturing a control device comprising an actuator for generating a haptic feedback. The method includes providing at least two flat anchors each of which comprises a connecting element for connection to a support component. The connecting element is arranged differently on each of the flat anchors. An actuator solenoid and the support component are mounted within the control device. A distance between the actuator solenoid and a predetermined point on the support component is determined to obtain a determined distance. One flat anchor is selected from the flat anchors based on an actual distance to the actuator solenoid when the one flat anchor is connected to the support component corresponding to a specific requirement, the actual distance being determined based on the determined distance. The one flat anchor selected is mounted within the control device.

Method and arrangement for manufacturing a control device offering haptic feedback

The present disclosure relates to a control device with at least one touch-sensitive input surface that can be activated for haptic feedback with an electromagnetic actuator, where the actuator comprises an actuator coil and an armature that is activated by energizing the actuator coil. The control device is divided into at least two control assemblies at least one of which has a touch-sensitive input surface and an armature connected therewith. These at least two control assemblies are installed at a minimum spacing from each other on a common circuit board, which in turn is connected with a common carrier element, whereby the armatures protrude through the circuit board with play. On each carrier element, an actuator coil at a spacing x from the armature of the respective control assembly is installed. The present disclosure also refers to a process for manufacturing the control device.
