Abstract
A heat-sensitive switch includes a first terminal, a second terminal away from the first terminal, a reverse spring reversing at a set temperature and having an opening part and positioned between the first and second terminals, and a junction spring positioned between the reverse spring and the second terminal without being fixed, integrally having a junction part protrusively positioned and in contact with the first terminal via the opening part, and also having an outer peripheral part in contact with the second terminal. An electric connection between the first and second terminals is formed, and when the reverse spring reverses at the set temperature, a force is applied to the junction part of the junction spring in the direction away from the first terminal, whereby the electric connection is cut.
