Abstract
A five pin protector module for telephone circuits comprises two input pins, two output pins and a grounding pin, all on an insulative base. The electrical current path between each input pin and its respective output pin comprises an electrically conductive arm, a current responsive assembly and an electrically conductive helical spring. The module contains a bidirectional voltage sensitive switch which prevents input voltage surges from reaching the output but, instead, conducts them to a grounding member to which the grounding pin is attached.
