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： 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.

摘要： A temperature-dependent switch having a housing with an upper part and a lower part, wherein a first and a second stationary contact are arranged on the housing, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the movable contact member against the first contact and thereby produces an electrically conductive connection between the two contacts via the contact member, and, in its second switching position, keeps the movable contact member spaced apart from the first contact. A closing lock prevents the switch, once having opened, from closing again by locking the switching mechanism permanently in its second switching position in a mechanical manner. The closing lock comprises a substantially disc-shaped locking element and a first latching member, which, in order to lock the switching mechanism, interacts in the second switching position with a second latching member that is arranged on the movable contact member.

摘要： 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.

摘要： A surge protective device (SPD) module includes a module housing, first and second module electrical terminals mounted on the module housing, a gas discharge tube (GDT) mounted in the module housing, and a fail-safe mechanism mounted in the module housing. The GDT includes a first GDT terminal electrically connected to the first module electrical terminal and a second GDT terminal electrically connected to the second module electrical terminal. The fail-safe mechanism includes: an electrically conductive shorting bar positioned in a ready position and repositionable to a shorting position; a biasing member applying a biasing load to the shorting bar to direct the shorting bar from the ready position to the shorting position; and a meltable member. The meltable member maintains the shorting bar in the ready position and melts in response to a prescribed temperature to permit the shorting bar to transition from the ready position to the shorting position under the biasing load of the biasing member. In the shorting position, the shorting bar forms an electrical short circuit between the first and second GDT terminals to bypass the GDT.
