Exploding foil .switches used to couple very large amounts of stored energy to impulsively driven loads seem to attain a limit in the rapidity at which they open. A materials science analyses of the changes which take place during the opening of copper and aluminum foil fuses, which use 100 glass beads as the quenching medium was conducted. A suggested sequence of events which takes place in SHIVA opening switches which interrupt current from 45 KJ of stored energy during the 200 n seconds required to open these switches, is proposed.
