PROBLEM TO BE SOLVED: To provide a pressure switch 100 with a temperature sensor whose internal structure is simple, with high assembling characteristics and reliability, at a low cost. SOLUTION: An inversion plate 5 which inverts according to the pressure of a detected fluid is provided. A rod-like temperature sensor 20 is provided so as to penetrate the central part of under-pressure operation mechanisms 5, 6, 7, and 8 up to the inversion plate 5. On end of the temperature sensor 20 is made to press the inversion plate 5 by an elastic member 19 whose one end is fixed to a housing 2 side, so that the inversion plate 5 is interlocked with the temperature sensor 20. Thus, one end of the rod-like temperature sensor 20 is made to contact the inversion plate 5, for raised detection precision and detection response for the temperature of the fluid which is to be detected. Since the temperature sensor 20 penetrates the central part of the under-pressure operation mechanisms 5, 6, 7, and 8 so that the temperature sensor 20 is pressurized with the elastic member 19, such operations as connecting/fixing and assembling of the temperature sensor 20 are simplified.
