摘要： 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.
