チ装置。 A switching device that performs switching by detecting the weight of an object to be placed and a switching device by detecting the temperature of the object, comprising: a placing section for placing the object and including a temperature-sensitive magnetic material; A base placed below this mounting part, a permanent magnet having a magnetic pole in the axial direction of the reed switch and placed on the outer periphery of the reed switch, and a permanent magnet placed on the outer periphery of the reed switch on each magnetic pole side of the permanent magnet. a reed switch device having a pair of ferromagnetic materials provided between the mounting section and the base; a movement mechanism;
The weight sensing elastic member is disposed between the base and the mounting portion, and the weight sensing elastic member is elastically deformed by the gravity of the placed object to cause the temperature sensitive magnetic body to move toward the temperature sensitive magnetic body. The weight of the object to be placed is detected by switching the reed switch in contact with a ferromagnetic material, and switching the reed switch again when the temperature of the temperature-sensitive magnetic material reaches a magnetic transformation point or higher. A switch device featuring:
