The switch works! Einwandfrei.hingegen the shortcomings listed here, I can not find anything that was spricht.ich against this adapter also only unsettled as I have read here that it does not work when both light sources send (red light on) .For me send always both sources (cables of both appear red light) .However it affects the adapter and by no means it is only the signal again, which also sharply switched is fitted.For this unbeatable price you can not einwenden.top buy recommendation.
