I have seen a mag switch with a live mag when selected off but it also allowed a live mag when selected to the other mag and so would have been caught by my check. So my question is if the mag switch grounds the mag when individually selecting a mag but then allows a mag to live when in the off position. Has anyone seen that ?

I think that failure mode is essential impossible and so a running shut down check and the normal precautions around props are sufficient and therefore a full dead mag check where the mags are turned off with the engine running is not really required
