A method for producing a plastic composite panel which is provided as a layer structure. The method includes providing a film layer structure comprising an adhesive layer which is arranged between two transparent plastic films. The film layer structure is pre-molded to assume an approximately final shape and is arranged in a molding tool so that a first main surface of the film layer structure is towards the molding surface of the molding tool and so that a cavity is formed between the second main surface of the film layer structure and a surface of the molding tool. The film layer structure is then back-molded in a thermal molding method step while introducing a thermoplastic material into the cavity to provide the layer structure. A pre-molding and back-molding step, a rigidification of the thermoplastic layer, and a demolding of the layer structure is further performed.

Plastic composite panel and associated production method

The present disclosure relates to a control element, comprising a carrier, an actuating member defining a touch-sensitive input surface, whereby the actuating member is movably installed on the carrier substantially parallel to the plane formed by the touch-sensitive input surface in a movement direction; an actuator to provide a movement from a resting position in movement direction of the actuating member relative to the carrier for providing a haptic feedback, whereby furthermore at least one permanent-magnet pair is arranged between the carrier and the actuating member to guide, in particular to stabilize the movement of the actuating member and/or the return of the actuating member into the resting position.

Control element with haptically movable touchpad or touchscreen and with magnetic return

A rocker switch includes a housing. An actuating part is pivotably mounted at the housing and includes at least two opposing actuating surfaces with two opposing actuating directions associated thereto. At least one actuating surface includes a backlit lighting surface. At least one lighting device is attached to the housing for backlighting the lighting surface. The rocker switch includes least one electromechanical pushbutton and at least one multiple-part telescoping light duct. At least one plunger is displaceably supported at the housing. The at least one plunger acts through the actuator part on the electromechanical pushbutton and the at least one light duct so as to define a light channel between the at least one lighting device and the lighting surface. The at least one light duct having a tubular lower light duct section corresponding to the electromechanical pushbutton and a tubular upper light duct section corresponding to the lighting surface.
