Abstract
A telephone protector comprises an encapsulated bidirectional voltage sensitive switch having three terminals protruding therefrom, one of the terminals being a grounding terminal. There is an elongated shorting bar substantially orthogonal to the three terminals and a metal fusible pellet in direct physical contact with both the grounding terminal and the shorting bar. There is a spring which impels the shorting bar into contact with the other two terminals when the fusible pellet melts.
