A driving step portion 12a provided at an intermediate portion of the operating shaft 12 engages with a driving plate portion 13a of a movable contact plate 13 of a contact mechanism S1 for generating a control signal. The movable contact plate 13 includes
As is well known, a driven plate part 13c is provided between the drive plate part 13a and a quick reversal spring 13b, and a movable contact 13' is provided at the tip of the driven plate part 13c. It contacts and separates from a fixed contact 14' provided at the end.

A movable contact 17' is fixed to the end of the movable contact plate 17,
It contacts and separates from a fixed contact 18' provided on the movable inner end 18a of the terminal plate 18. 19 is the adjustment screw, and the operation setting of the contact mechanism S2 for generating the alarm signal is primarily performed by the length of the operating shaft.

効果を有する。 As described above, the present invention has a spring for temperature setting opposed to the thermally responsive body via an actuating plate, and the actuating plate is provided with an actuating shaft that reaches the switch box.
The switch box is provided with a temperature control contact mechanism and an alarm contact mechanism, and a movable contact plate biased in the opening direction of the temperature control contact mechanism and a movable contact plate biased in the opening direction of the alarm contact mechanism in the axial direction of the operating shaft. A biased movable contact plate is disposed, and when the actuating shaft moves when the temperature rises, the actuating shaft has a quick reversal spring by pressing the driving plate part of the temperature control contact mechanism in the first stage. The movable contact plate is driven to move the movable contact in the direction opposite to the direction of movement of the actuating shaft so as to contact the fixed contact, and in the second step, the actuating shaft presses the drive plate part and operates the alarm contact mechanism. The movable contact plate is driven to move the movable contacts in the same direction of movement and bring them into contact with the opposing fixed contacts;
The contact mechanism for generating a temperature control signal and the contact mechanism for generating an alarm signal can be operated in stages during the operation process of the operating shaft of the thermostat, and in particular, the operating shaft is closed at a temperature in the first stage of its operation process. Since the control signal generating contact mechanism is controlled via the drive plate portion of the quick action mechanism provided on the movable contact plate, unreasonable force is applied to the contact portion of the first stage contact mechanism. It is possible to maintain durability with stable operation without any problems, and it is possible to control the operation of the contact mechanism for generating alarm signals in addition to the contact mechanism for generating control signals when the operating axes operate in the same axial direction. Therefore, it is possible to compactly incorporate two contact mechanisms that perform different functions into one switch.
