Abstract
The inventive control element is provided with a mechanical actuator () and an electrical or electromechanical switching element (), whereby the switching element () comprising of at least one push button () reacting upon pressure. Thereby, the actuator () is arranged elastically or resiliently relocatable or tiltable with respect to the switching element () or the push button () respectively and an actuating cam () is further provided at the actuator () facing the push button (), whereby the actuator () and the switching element () are not directly connected to each other. The dividing of the control element into two parts, one mechanical actuating part () and one electrical switching part (), permits the replacement or exchange only of the mechanical actuating () part without any influence to the electrical switching part (). The replacement or exchange therefore may take place without the need of desoldering of the electrical switching part () from its printed circuit board or from its connected wires.
