摘要： A temperature switch 1 includes first terminal unit 2 having a first terminal 5 and a first fixed contact 6, a switch body unit 3 including a bimetal element 22 in which both ends engage a movable plate 15 holding, via an tongue portion 17, first and second fixed contacts 6 and 8 arranged in an internal center portion of an insulation material 10 at prescribed intervals and also holding a movable contact 18 arranged above them, and a second terminal unit 4 having a second terminal 7 and the second fixed contact 8. The first terminal unit 2, the switch body unit 3, and the second terminal unit 4 are sequentially arranged in line. At an ambient temperature, the bimetal element 22 deforms into a convex shape in the contact direction so as to push out the tongue portion 17 and the movable contact 18 at the center of the convex shape, and the movable contact 18 is closed with respect to the first and second fixed contacts 6 and 8 so that a current flows between the first and second terminals 5 and 7. At an ambient temperature equal to or higher than a prescribed value, the bimetal element 22 causes inversion to become concave in the contact direction, releases the biasing force of the spring property toward the space above the tongue portion 17, the movable contact 18 moves away from the first and second fixed contacts 6 and 8, and a current is cut off.

摘要： A thermal protector has superiority in current responsiveness or thermal responsiveness with a simple configuration that does not need a separate manufacturing step of incorporating a resistor. At a stage of press processing for cutting from an original material, a movable plate body part of a movable plate is partitioned into a narrow-width part and a wide-width part by a slim hole. The movable plate is assembled to a fixed conductor with columns of an insulator, a bimetal is assembled to the movable plate, the entire configuration is pressed down by a resinous block, and the entire fixing part is fixed by melting tips of the columns. The wide-width part serves as a normal movable plate, whereas the narrow-width part serves as a conductor in a normal state and as a resistor against an overcurrent.

摘要： A temperature detection element of a temperature sensor is connected to a print wire and three print wires for an input and output of a print substrate, one end of a lead wire for a connection is connected and fixed with solder to an external circuit for connection electrodes of the print wire, and the other end is externally drawn out of a sealing member of a hardened resin. Within the housing, the entire bottom surface of the print substrate is supported by a lower fixed member, and an end, closer to an opening part of the housing, of the print substrate, is sandwiched and fixed by an upper fixed member and the lower fixed member. The housing is configured with the same material and size as the housing of the temperature control element, and the temperature detection element inside is placed at a position approximated to a placement of a thermal response element of the temperature control element. By using an adhesive having a different thermal conductivity, a thermal characteristic of the temperature sensor can be varied.
