  • Patent number: 8636391
    Abstract: A rod-shaped retrofit lamp may have a mechanical sensing unit, and a current path has a plurality of electrically conductive sub-segments of which a first sub-segment is connected to the associated pin and of which a sub-segment is connected to the lamp's electronics unit, wherein the mechanical sensing unit is elastically pushed in counter to its projection direction from a released condition into an engaged condition and interacting with two current paths in such a way that the respective current path's first and second sub-segment will have been galvanically mutually coupled when the sensing unit is in the engaged condition so that the respective current path will have been closed and associated pin thereby electrically connected to the internal electronics unit.
