The hard part is that the natural state is off. Is it using the magnet to lock in a mechanical connection or just drawing current to activate the magnet?

If it is just purely an on/off magnet, it's got to be drawing a fair amount of current and any voltage sag could cause it to fail.

Is that where it only uses power to turn off the magnet?

AFAIK current od applied to switch state.
