Disclosed is a module () having pins () connected to respective conductor tower strips (). Pairs (and) of the conductor tower strips are spring biased toward each other to capture therebetween respective PTC current limiting elements (). A spring memberis connected to a ground pin () at one end, and to an overvoltage sensitive assembly at the other end, via a soldered heat transfer member (). The overvoltage sensitive assembly includes overvoltage semiconductor devices () soldered thereto. When an overvoltage condition is sensed, the heat generated by the devices melts the solder between the heat transfer member () and the spring member (), whereby lateral arms () of the spring member () move and engage the conductor tower strips (). The tip and ring pins () of the module () are not only shorted together, but are shorted to ground.

Primary telephone line protector with failsafe

A telephone line protection module having a printed circuit board base with conductive paths connected to pins of the module. Overvoltage sensitive semiconductor devices are soldered to the ends of a conductive bridge, and the bridge is spring-biased between a module cover and the conductive bridge. The semiconductor devices are thus forced into electrical contact with the printed circuit paths. In addition, in the event the semiconductor devices are thermally destroyed, the conductive bridge is forced by the spring into direct contact with the printed circuit paths.
