Abstract
An overvoltage protector for protection of telecommunication equipment having a pair of line terminals, and a respective pair of levers forming part of the ground circuit, with an overvoltage protective device bonded under tension between each line terminal and each respective lever. When an overvoltage destroys one or other device, or the bond between the line terminal and the respective lever disappears, that lever pivots about a single fulcrum under a force applied by a spring and the end of that lever contacts the line terminal. This ensures an electrically conductive relation between the line terminal and the ground circuit. As a result, the equipment to which the overvoltage protector is applied is protected from lightning and successive overvoltage occurrence.
