Patent ID: 7292131

Claim:
A heat-sensitive switch, comprising: a first terminal; a second terminal positioned away from said first terminal; a reverse spring, which reverses at a set temperature being set in advance, having an opening part and positioned between said first terminal and said second terminal; and a junction spring, positioned between said reverse spring and said second terminal without being fixed, integrally having a junction part that passes through the junction spring and is protruded and positioned to be in contact with said first terminal via said opening part, and also having an outer peripheral part in contact with said second terminal, whereby an electric connection between said first terminal and said second terminal is formed, and when said reverse spring reverses at said set temperature, a force is applied to said junction part of said junction spring in the direction away from said first terminal, whereby said electric connection is cut, wherein said junction spring is positioned between said reverse spring and said second terminal without being fixed, having a bridge part protruded and positioned in the shape of arch and provided with a center junction part at the center of said bridge part, and also having a pair of outer junction parts provided on the both sides of said bridge part via slits, each of said outer junction parts being provided with bent parts protrusively bent in the same direction as the protruding direction of said bridge part, so that said center junction part is protruded and positioned to be in contact with said first terminal via said opening part, and so that said outer junction parts are in contact with said second terminal, whereby said electric connection between said first terminal and said second terminal is formed.
