Abstract
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.
