Abstract: Thermal fuses and related methods of operation are disclosed. In some embodiments, a thermal fuse may include an insulating component and two electrodes operatively connected to the insulating component. Based on a difference in the thermal coefficients of expansion, the insulating component may expand axially relative to the electrodes with increasing temperature. As the insulating component expands the two electrodes may be moved axially apart to transition between an open and closed configuration. In some embodiments, the thermal fuse may transition between the open and closed configuration depending on whether or not an operating temperature of the thermal fuse is above or below a threshold temperature.
