Abstract
A shorting switch eliminates arcing faults in power distribution equipment. The shorting switch includes an insulating tubular housing; a first contact; a second contact; and an insulator between the first and second contacts in the insulating housing. The insulator prevents electrical connection of the first and second contacts. First and second terminals are respectively electrically connected to the first and second contacts. A wave spring mechanism moves the first and second contacts toward closure. A slug and an activated charge mechanism drive the insulator from between the first and second contacts, in order to electrically connect the first and second contacts.
