摘要： A temperature-dependent switching mechanism for a temperature-dependent switch, having a temperature-dependent bimetal snap-action disc, a temperature independent snap-action spring disc, an electrically conductive contact member to which the bimetal snap-action disc and the snap-action spring disc are captively held, so that the bimetal snap-action disc, the snap-action spring disc and the contact member form a switching mechanism unit captively held together, and a switching mechanism housing having a base body. The base body of the switching mechanism housing surrounds the switching mechanism unit from a first housing side, a second housing side, and a housing peripheral side. The switching mechanism housing comprises a first opening in the base body on the first housing side, through which the contact member is accessible from outside the switching mechanism housing, and a second opening in the base body on the second housing side, through which the contact member is accessible from outside the switching mechanism housing.

摘要： This disclosure provides a circuit board assembly and a manufacturing method thereof. The circuit board assembly includes circuit board, embedded chip, heat dissipation assembly and temperature switch structure. The temperature switch structure includes a first metal layer and a second metal layer stacked on each other. The first metal layer of the temperature switch structure is electrically connected to the circuit board and is thermally coupled to the embedded chip. A thermal expansion coefficient of the first metal layer is different from a thermal expansion coefficient of the second metal layer so that the temperature switch structure is deformed in response to a temperature change of the embedded chip to be in contact with or spaced apart from the second electrically conductive contact of the heat dissipation assembly.

摘要： A temperature-dependent switching mechanism for a temperature-dependent switch, having: a temperature-dependent bimetal snap-action disc having a first through hole; a temperature independent snap-action spring disc having a second through hole; and an electrically conductive contact member including a main body that passes through the first through hole and the second through hole. The contact member includes a support shoulder projecting radially from the main body, a first locking element projecting radially from the main body and arranged on a first side of the support shoulder, and a second locking element projecting radially from the main body and arranged on a second side of the support shoulder opposite the first side. The temperature-dependent bimetal snap-action disc and the snap-action spring disc are arranged between the locking elements and the support shoulder and are each held captive, but with clearance, by these on the main body of the contact member.

摘要： A method for detecting orientation of an integrated circuit is disclosed. The method includes moving, in response to a gravitational force, a mobile metallic piece in an evolution zone of a housing. The housing is formed in an interconnect region of the integrated circuit. The housing includes walls defining the evolution zone. The walls are formed within multiple metallization levels of the interconnect region. The walls include a floor wall and a ceiling wall. At least one of the floor wall and ceiling wall incorporate a pointed element directing its pointed region towards the mobile metallic piece. The pointed element delimits an open crater in a concave part of a projection. The method further includes creating an electrical signal by movement of the mobile metallic piece at a plurality of electrically conducting elements positioned at boundary points of the evolution zone and detecting the electrical signal by a detector.

摘要： An example microelectromechanical structures (MEMS) switch includes a body having a first end and a second end opposite the first end. The body extends from a base at the first end and has a first width. The MEMS switch further includes a bridge extending laterally from the body at the second end, and a spine extending between the bridge and the base. The spine has a second width smaller than the first width. At least one of the spine or the body includes a first material with a first thermal coefficient and a second material with a second thermal coefficient different from the first thermal coefficient.

摘要： A breaker comprises: a fixed piece having a fixed contact; a movable piece having a movable contact and pressing the movable contact against the fixed contact to contact therewith; a thermally-actuated element for shifting the movable piece from a conduction state in which the movable contact contacts with the fixed contact to a turn-off state; a PCT thermistor; and a resin case. The fixed piece has a contacting portion contacting with the PCT thermistor. The resin case has a bottom surface provided with a concave portion. In a planar view when the fixed piece is viewed from the PCT thermistor, the contacting portion is disposed within the concave portion. The concave portion has a bottom recessed from the bottom surface of the resin case to prevent the bottom from protruding outwardly from the bottom surface when the thermally-actuated element is deformed.

摘要： A temperature-dependent switch comprising a housing, which comprises a cover part and a lower part, wherein an insulating foil is arranged between the cover part and the lower part. The temperature-dependent switch further comprises a first external contact surface provided externally on the housing, a second external contact surface provided externally on the housing, and a temperature-dependent switching mechanism arranged in the housing. The temperature-dependent switching mechanism, depending on its temperature, establishes or opens an electrically conductive connection between the first and the second external contact surfaces. The insulating foil is at least partially coated or printed with a sealing agent which, for sealing the housing, contacts the cover part and/or the lower part in a sealing area.

摘要： A current cut-off device 1 includes a plate-shaped terminal piece 2 having a contact 21, a movable piece 4 including an elastic portion 44 formed in a plate shape so as to be elastically deformed and a movable contact 41 arranged at one end portion of the elastic portion 44 and having the movable contact 41 so as to be pressed against and in contact with the contact 21, and a thermally actuated element 5 which biases the movable piece 4 by deforming in accordance with a temperature change and causes a state of the movable piece 4 to be shifted from a conductive state in which the movable contact 41 is in contact with the contact 21 to a cut-off state in which the movable contact 41 is separated from the contact 21. When the state of the movable piece 4 is shifted from the conductive state to the cut-off state, as the movable contact 41 moves, it gets over the contact 21.

摘要： A temperature-dependent switch comprises a first stationary contact, a second stationary contact, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the contact member against the first contact and thereby produces an electrically conductive connection between the two contacts. In its second switching position, the switching mechanism keeps the contact member spaced apart from the first contact. The temperature-dependent switching mechanism further comprises first and second temperature-dependent snap-action parts which switch from geometric low-temperature configurations to geometric high-temperature configurations when exceeding first and second switching temperatures, respectively, and switch back when subsequently falling below first and second reset temperatures, respectively. Switching the first and/or the second snap-action part from its geometric low-temperature configuration to its geometric high-temperature configuration brings the switching mechanism from its first switching position to its second switching position.
