摘要： An electrical switching device includes a housing, a base attached to the housing, two non-actuated electrical contacts supported in the housing, and an actuator assembly contained within the housing. The actuator assembly includes a movable contact for engaging the non-actuated electrical contact and a wire element formed of a shape memory alloy. Applying an electric current to the wire element causes the actuator to either pivot or rotate the movable contact to either engage or disengage the non-actuated electrical contacts.

摘要： A micro-electromechanical actuator includes a pair of elongate layers capable of being heated with an electrical current to thermally expand and to perform work. A pair of spacers separates the elongate layers from each other. The spacers are arranged at respective opposite ends of the elongate layers and are fast with the layers so that the actuator is deflected when one of the layers is heated.

摘要： A thermal switch assembly has a contact member of shape memory alloy sandwiched between a pair of electrically conductive outer members. A contact arm on the contact member has a deformed shape at normal temperatures and a recovered shape at elevated temperatures. The contact arm occupies two different positions in its deformed and recovered shapes, and provides a current path between the outer members in one position while interrupting the current path in the other position.

摘要： A microminiature switch for digitizing different-valued external conditions, such as pressure, temperature of acceleration, is disclosed. The switch includes a silicon wafer having a deflectable, reduced-thickness membrane adapted to move from a relaxed position toward increasingly flexed or bulged positions in response to greater-value changes in such external condition. Movement of the membrane from its relaxed position to more strained positions establishes electrical contact between a common terminal and first one and then progressively more switch-state terminals in the switch, wherein the number of switch states which are closed corresponds to the external condition acting on the switch.

摘要： A thermally sensitive switch has a thermally conductive body within which is a chamber into which extends at least one electrically conductive terminal. Occupying the chamber is an elastomeric body which is expansible and contractile in response to increases and decreases, respectively, in its temperature. The elastomeric body may be normally conductive or normally nonconductive, but in either event is conductive when in its expanded condition. When in its expanded, conductive condition, the body engages the terminal and is operable to establish a current path through the body to the terminal. The body may function as an on-off switch or as a rheostat, depending upon the composition of the body.

摘要： Apparatus for protecting the armature of an electric motor against excessive temperatures comprises a resiliently compressible and expansible pad in the armature circuit and composed of thermally sensitive, non-conductive material containing a plurality of conductive particles engageable with one another when the pad is in a compressed condition to establish a conductive path through the pad. The pad normally is maintained in a compressed, conductive condition by resilient force applying means which is of such resilience as to permit expansion of the pad in response to an increase in its temperature and render the pad non-conductive.

摘要： The current interrupter according to this invention has for its object to prevent overheating of electric cigar lighters. Said interrupter includes a tube which is made of thermoplastic resin of low inflammability. Within said tube, the terminal of the cigar lighter and an auxiliary terminal are placed coaxially and in contact with each other by means of a spring. When the cigar lighter has reached above the predetermined temperature, said thermoplastic tube softens and deforms axially by the action of the spring whereby as the contact between said terminals breaks, the current supply to the cigar lighter will be suspended at once.
