ABSTRACT:
A miniature back-up overvoltage protection apparatus for use on an overvoltage protection device includes a housing adapted to be removably mounted on the first and second terminals of an overvoltage protection device. A dielectric is disposed within the housing and is sandwiched between two electrically conducting members done of which is in contact with one end terminal of the overvoltage protection device. A unitary clip is adapted to removable retain the overvoltage protection device and to urge a pair of back-up overvoltage protection apparatuses against the distal terminals of the overvoltage protection device with the clip making electrically conducting contact with the third terminal of the overvoltage protection device, the second conducting member and to the ground terminal of the telephone line system.
