Abstract: An actuator device which includes a fixed support structure, an actuation member movable, a biasing member tending to maintain the actuation member in a rest position, a shape-memory wire connected to the structure and to the actuation member, and an electric circuit for supplying an electric current to the shape-memory wire. The circuit includes a pair of terminals. One end of the shape-memory wire is connected to a first terminal. The circuit includes further an electric switch, including a first conducting member electrically connected with the second terminal, and a second conducting member carried by the actuation member and electrically connected with the other end of the shape-memory wire. The switch is closed when the actuation member is in the rest position, and remains closed until when the actuation member reaches a working position, and opens when the actuation member passes beyond the working position.

Abstract: A system includes a first electrically conductive electrode and a second electrically conductive electrode. The system further includes a magnetic field source. The system also includes a magnetic shape memory (MSM) alloy positioned within a magnetic field of the magnetic field source with a portion of the MSM alloy being coupled with the first electrically conductive electrode. The magnetic field causes the MSM alloy to bend to contact the second electrically conductive electrode when the MSM alloy is in a first state. The magnetic field has no or negligible effect on the MSM alloy when the MSM alloy is in a second state.

Abstract: A breaker is provided with: a movable piece (4) that has an elastically deformable elastic portion (43) and a movable contact on the tip of the elastic portion (43) and that presses the movable contact into contact with a fixed contact; a thermal actuator element (5) that is formed into a shape with a convex surface and is deformed by a change in temperature, thereby actuating the movable piece (4) so that the movable contact separates from the fixed contact; and a resin case (7) which houses the movable piece (4) and the thermal actuator element (5). The bottom surface of the base end (42a) of the movable piece (4) is positioned lower than the top (5a) of the upper surface of the thermal actuator element (5) by a distance (D). Thereby, a stable temperature adjustability and a resistance value are ensured in a breaker used as a protection device for a secondary battery with miniturization brought into realty.

Abstract: A circuit interruption device includes a support, a set of separable contacts, a first member movable between an OFF position and an ON position, a second member, and a transport mechanism that includes a shape memory alloy element. When the first member is in the OFF position, the second member is in an extended position, the shape memory alloy element is in its first shape, and the first surface and the another first surface are engaged with one another and resist movement of the first member away from the OFF position. Responsive to an electrical pulse, the shape memory alloy element transforms into its second shape and moves the first member toward the ON position. When the second member is in the extended position, the another second surface engages with the second surface to resist movement of the first member away from the ON position.
