ABSTRACT:
A pair of conductors in an electric switch are kept in electrical contact by a wire gripped between the conductors and a base against which the conductors are biased. A pedestal of meltable material in a well, covered by a resilient sheet, supports the base in its position. A spring urges the wire out of engagement with the conductors, and is successful when the pedestal melts and fails to support the base, the base meanwhile distorting the resilient sheet. After the disengagement of the wire from the conductors, the pedestal resolidifies in its original shape as the resilient sheet regains its configuration. A reset button is coupled to re-engage the wire with the conductors.
