Abstract: A steering wheel having a steering wheel body (10) having a first force transmitting component, and a horn actuation element. The horn actuation element having a horn actuation surface (23) and having a second force transmitting component. A load cell (30) is provided having a sensitive element that changes at least one of its electrical properties in response to a compression force. The sensitive element placed between the first and second force transmitting components. At least one elastically deformable element is provided between the steering wheel body (10) and the horn actuation element. When a pushing force is applied to the horn actuation surface (23) the force applied to the sensitive element changes. In a resting state of the steering wheel a compression force is applied to the sensitive element by the first and second force transmitting components by a preload and in that the compression force applied to the sensitive element is reduced when a pushing force is applied to the horn actuation surface (23).
