Hello.
In order to identify all the wires under my layout and connect them properly, I built a "continuity tester" with a beeper and a 9 V battery. Now I connected it between my rails in a station, to ensure that there is no short circuit. I was suprised to hear a very short "beep" when I switched some Rokuhan turnouts (by hand), especially when switching to deviant position 
; it occurs in a random way, not every time. My turnouts are not "power routing", i.e. the current flows continuously ( "the 2 screws" are in place), the current switching will be performed by the relays controlling the turnouts (all sections must be switched off, not only one rail), maybe that the relays will cause transients too because there is a delay between the relay and the turnout. For me this not a problem because, due to the running "one train at once", the turnouts will be only activated when all trains stop, no power on the track, and I will wait before going on. But I think it could cause issues with position detectors if there is continuous power on the track (DCC ? 
), this could be a cause of malfunction very difficult to identify, especially in conjunction with self built position detectors (like mine, with a time constant to avoid flicker), it could cause "phantom triggering" in some cases if the detectors are (too) sensitive to short transients to go "on".
