摘要： PROBLEM TO BE SOLVED: To provide a switch suitable for integration with a simple structure, capable of suppressing a cost low, by arranging electrodes in a cavity inside a magnetic circuit formed by a leakage magnetic field of the magnetic circuit, and by controlling a magnetic field distribution formed in the cavity by utilizing a magnetism change, changing by a temperature, of a temperature sensitive magnetic substance. SOLUTION: This temperature sensitive switch 10 has a main magnetic circuit and a sub-magnetic circuit. The main magnetic circuit is composed of a magnet 16, a temperature sensitive magnetic substance 19, an electrode 13, a main magnetic circuit aperture 15, namely, a part of the space inside a cavity, an electrode 14, and a temperature sensitive magnetic substance 20, and the sub-magnetic circuit is composed of the magnet 16 and a cavity space in the periphery of the magnet 16. As the temperature sensitive magnetic substances 19, 20 lose magnetism over the Curie temperature, such a formation is applied that, taking the Curie temperature as a prescribed temperature set beforehand, a magnetic resistance of the main magnetic circuit is set smaller than that of the sub-magnetic circuit below the prescribed temperature, and that the magnetic resistance of the sub-magnetic circuit is set smaller than that of the main magnetic circuit above the prescribed temperature.

摘要： PROBLEM TO BE SOLVED: To provide a motor controller which can detect the position of a motor and the temperature in the motor without increasing the number of signal lines for temperature detection, by collectively processing signals from a temperature-sensitive switch which detects the temperature in the motor and a position detector for rotor. SOLUTION: A motor controller 21 controls the position of a motor 22 by detecting the position of the rotor of the motor 22 by means of a demodulator 32 and a variable magnetoresistive position detector 23 to which high-frequency power is supplied. A temperature-sensitive switch 24 is set up in the main body of the motor 22 and, at the same time, connected in series with one side of the high-frequency power supplied to the detector 23 and the controller 21 protects the motor 22 from overheating by controlling the power supply to the motor 22 by detecting the actuation of the switch 24 from the level fluctuation of the output signal of the position detector 23.

摘要： PROBLEM TO BE SOLVED: To have the stabilized temperature characteristic without generating looseness of a reed switch driving unit so as to improve the reliability by pressing a reed switch driving unit for contact with a part of a housing body or a part of a fixing member for holding. SOLUTION: A fixing member 1, which is made of the non-magnetic material and which is provided with a flange 1a as a holding part for preventing a fall in an end thereof, is inserted between an inner diameter part of a reed switch driving unit, which is formed of a temperature sensitive magnetic body 4 and permanent magnets 3a, 3b, and a housing body 5 for housing a reed switch, and a coil spring 2 is arranged in the periphery of the fixing member 1 made of the non-magnetic material. One side of this spring 2 is held by a part of the fixing member as a supporting part by pressing the lead switch driving unit for contact with the flange 1a as a holding part, which is provided in the fixing member 1 made of the non-magnetic material, with the elastic force thereof. A cut-out part 1b can be provided near the end in place of the flange 1a.
