I have trouble imagining a scenario in normal running where I would tolerate the non-derailing failing unless a minute went by since the last activation!
John,
Wonder if OP was thinking of letting coils cool off between activations. But you are right, you would have to mentally keep track of how long has lapsed for each switch before activating again. OWW my head hurts thinking of this for a large layout!
But after a few derailments (at the farthest inaccessible places, of course), I am sure the OP will move onto "plan B" or "plan C"
