Abstract
A surge protection device includes a metal terminal and a spring. The metal terminal is located between two metal oxide varistors, where the metal terminal extends beyond the metal oxide varistors. The spring has a flat surface that is connected to the metal terminal using a soldering paste. The flat surface has a bend on one end which forms a gap between the flat surface and the metal terminal.
