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 switch includes an elastically deformable movable plate, a movable contact on the movable plate, a fixed contact facing the movable contact, a thermally deformable member, a vibration suppression section, and a cover. The thermally deformable member is elastically deformed in accordance with a temperature change to elastically deform the movable plate such that the movable contact is in contact with the fixed contact or spaced apart from the fixed contact. The vibration suppression section suppresses vibrations of the movable plate by contacting a fixed-edge side when the movable plate is elastically deformed to shift the movable plate from being in contact with the fixed contact to being spaced apart therefrom. The cover surrounds the movable and fixed contacts, and the vibration suppression section is a projecting section provided on the cover.

摘要： A thermal protector includes, in a fixed manner, a first terminal and a second terminal that are respectively connected to external circuits, at lower left/right ends of the longitudinal directions of a base, and a right end at which a movable plate and a bimetal are superimposed is fixed to the right end of the upper surface of the base and is connected to the second terminal. A fixed contact is fixed to an internal end of the first terminal that is exposed in the left end of the base. A movable contact is fixed at a position facing the fixed contact on the lower surface of the left end of the movable plate. A partition wall that encloses the movable contact and the fixed contact from three directions is provided and bent plate planes are formed on both sides of the movable plate in the vicinity of the movable contact. The bent plate planes adjust the flow direction of hot air in cooperation with the partition wall so as to prevent a malfunction of a breaking arc flying to surrounding conductive members.

摘要： A movable flat surface portion, which rises in conjunction with the upward movement of a facing surface, first causes an edge of the movable flat surface portion to abut a flat surface portion, second brings an entirety of a surface of the movable flat surface portion into intimate contact with the fixed flat surface portion as a result of the movable flat surface portion acting against elastic resistance thereof in accordance with upward inertia, third forms, in accordance with a restoring force resulting from the elastic resistance thereof, a gap in the intimate contact with the fixed flat surface portion in a manner such that the forming of the gap starts with an end side continuous with the end of the facing surface, and fourth stabilizes a position shape such that the edge of the movable flat surface portion is a portion that ultimately comes into contact with the fixed flat surface portion.
