    Patent number: 6175480
    Abstract: A varistor with no connecting legs extending from it, is mounted in a slot formed in a printed circuit board. The printed circuit board carries the normal circuit tracks. The physical and electrical connection between the printed circuit board and the varistor is achieved by the use of solder. When the varistor overheats to a temperature beyond a predetermined temperature, the solder melts and the varistor is separated from the printed circuit board. A leaf spring which is biased when the varistor is inserted into the slot pushes the varistor out of the slot when the solder melts. Alternatively, when the solder melts gravity causes the varistor to fall out of the printed circuit board.
