I have a large number of Ross switches equipped with DZ1000 machines w/DZ 1002 controllers. Here's an exchange I just had with Dennis Zander who manufactures these machines:

Dennis,

I've wired a number of switches for automatic non-derailing. After one of these switches has been automatically thrown, is the switch electromagnet still drawing current? Said switch seems to remain "quiet", even when a car is sitting on the triggering, insulated approach rail. This question occurred to me when I wired them and appeared today, in a slightly different context, on the OGR Forum.

Hi,

The switch machine motor has power removed when the final position is reached.

Dennis

So, no possibility of frying one of these, even if a train sits on the control rail indefinitely.
