A thermally responsive switch (1) includes an airtight container (2) including a metal housing (3) and a header plate (4), conductive terminal pins (10A, 10B) airtightly fixed to the header plate (4), a fixed contact (8) fixed to the conductive terminal pin (10A), a thermally responsive plate (6) one end of which is conductively connected to and fixed to the inner surface of the airtight container (2) and the bending direction of which is reversed at a predetermined temperature, and a movable contact (7) fixed to the other end of the thermally responsive plate (6). In the thermally responsive switch (1), the movable contact (7) and the fixed contact (8) are composed of a silver tin oxide based contact and gas containing 50% or more and 95% or less of helium is encapsulated in the airtight container (2) in such a manner that gas pressure is equal to or more than 0.3 and equal to or less than 0.8 at ordinary temperature.

L'invention porte sur un interrupteur actionné thermiquement (1) qui inclut un contenant étanche à l'air (2) incluant un boîtier métallique (3) et une plaque de couvercle (4), des broches-bornes conductrices (10A, 10B) fixées de façon étanche à l'air à la plaque de couvercle (4), un contact fixe (8) fixé à la broche-borne conductrice (10A), une plaque actionnée thermiquement (6) dont une extrémité est connectée de façon conductrice et fixée à la surface interne du contenant étanche à l'air (2) et dont le sens de courbure s'inverse à une température prédéterminée, et un contact mobile (7) fixé à l'autre extrémité de la plaque actionnée thermiquement (6). Dans l'interrupteur actionné thermiquement (1), le contact mobile (7) et le contact fixe (8) sont composés d'un contact à base d'oxyde d'étain-argent et un gaz, contenant 50 % ou plus et 95 % ou moins d'hélium, est encapsulé dans le contenant étanche à l'air (2) de telle sorte que la pression de gaz est égale ou supérieure à 0,3 et égale ou inférieure à 0,8 à température ordinaire.
