A breaker has a movable piece which has an elastic part elastically deformable and a moving contact in one end portion of the elastic part, and which presses the moving contact against the fixed contact so that the moving contact contacts with the fixed contact; a thermally-actuated element deforming with a change in the temperature to actuate the movable piece so that the moving contact is separated from the fixed contact; a case housing the movable piece and the thermally-actuated element; and a terminal piece to be connected to an external circuit. The case has a side wall extending along a longitudinal direction of the elastic part. The terminal piece has a protruding portion which protrudes from the side wall toward the outside of the case. The side wall is provided, in its neighboring portion of the protruding portion, with a concave portion which dents inwardly of the case.

A breaker 1 includes a fixed piece 2 having a fixed contact 21, a movable piece 4 including a movable contact 41 and having the movable contact 41 so as to be pressed against and in contact with the fixed contact 21, a thermally actuated element 5 shifting the movable piece 4 from a conductive state to a cut-off state in accordance with a temperature change, and a case 7 accommodating the fixed piece 2, the movable piece 4, and the thermally actuated element 5. The case 7 includes a case main body 71 accommodating the movable piece 4 and the thermally actuated element 5, a lid member 81 covering a housing concave portion 73 of the case main body 71, and a metal plate 9 embedded in the lid member 81. Heat capacity of the metal plate 9 is larger than heat capacity of the fixed piece 2.

A thermally-sensitive cantilever sensor switch with a bimorph structure based on phononic cantilever structure. Phononic structure increases switch sensitivity to incident absorbed radiation. In embodiments the zero power switch is sensitive to ambient temperature and/or incident absorbed radiation. In embodiments, multiple switches are configured within a spectrometer to provide a means of monitoring toxic components within a media of interest such as smokestake effluents and hot emitters. The switch may be structured with sensitivity to incident radiation within wavelength bands ranging from ultraviolet (UV) to MHz.

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.

This invention is a thermally actuated switch in which a sealed vessel contains a fixed contact and a heat-sensitive-plate assembly that has a structure in which a movable contact is anchored to one lengthwise end of a heat-sensitive plate, one end of a metal support is anchored to the other end of said heat-sensitive plate, and the heat-sensitive plate is then drawn. The heat-sensitive-plate assembly has a dish-shaped drawn section near the middle of the heat-sensitive plate and has folded sections between the area where the movable contact is anchored and the widthwise edges of the heat-sensitive plate and also between the area where the metal support is anchored and the widthwise edges of the heat-sensitive plate.

A thermal protector may be used to switch an electric circuit of an electrical product. The thermal protector may include first and second terminals and a fixed contact connected to the first terminal. The thermal protector may include a movable contact facing the fixed contact. The thermal protector may include a bimetal and an elastically-deformable movable plate that engages the bimetal and on which the movable contact is fixed. The movable plate may be connected to the second terminal. The terminals may be held by respective insulating blocks. The bimetal or the moveable plate may be arranged to be within an area between the respective insulating blocks.

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.

A heating element has a plurality of serpentine portions made from a metal plate in ribbon form, disposed between the lid plate and the heat-reactive plate so as to be parallel thereto. At least two of the serpentine portions are disposed to face each other while sandwiching the conductive terminal pin. Each portion follows the inner peripheral surface of the housing and have planar portions facing each other.
