Abstract (en)

[origin: ES8609804A1] An electric switch in which a screen is inserted very quickly between two contacts at the moment when they part. The energy of the arc generated between the contacts inside a volume surrounded by an insulating mobile sheath is used to heat gases released, and the resulting gas pressure displaces the sheath quickly, so that the arc passing through an opening in the sheath is sheared between the sheath and the housing. This type of switch is used to advantage in protection apparatus designed to respond to an abnormal increase of the current flowing in a circuit in which they are series mounted, and in switches where rated current is high.
