Claims

[Scope of utility model registration request]

A fluid thermally expandable material such as wax is stored in the lower end of the case, the surface of this is covered with a flexible diaphragm, and a piston rod, a coil spring, and a push button that are pushed by the expansion of the thermally expandable material are stacked on top of this diaphragm. On the push button, one plate is formed into a substantially S-shaped planar shape, the center part bulges downward, the periphery is fixed to the case, and the push button is pressed from below with a force exceeding a certain limit. The center part of the reversing plate, which has the property of reversing upward when the button is pressed and returning to its original state when this force decreases below a certain limit, is fitted, and the upper end of the push button is connected to one electrode. A fixed contact is provided in the case, connected to a flexible plate supporting the movable contact, connected to another electrode, and with which the movable contact comes into contact when the reversing plate is reversed and the push button presses the flexible plate, The temperature switch further comprises a stopper provided on the case, with which the flexible plate abuts, prevents excessive displacement when the reversing plate is reversed upward, and ensures return of the reversing plate.
