    Abstract: A relay which is operable at very low power levels and which is highly versatile in its applications is shown to be characterized by high gain and high reliability and by simplicity of structure. The relay comprises a first terminal mounted on a base of electrically insulating material and a second electrically conductive member having a terminal portion secured to the base, having a contact arm movable between an open circuit position spaced from the first terminal and a closed circuit position engaging the first terminal, and having integral spring portions connecting the contact arm and terminal portion of the second member for normally biasing the contact arm to one of the noted circuit positions. The relay also includes an actuator wire secured between the base and the contact arm of the second member. The actuator wire is formed of a nickel-titanium alloy and is adapted to be deformed from an original length to a second length as the contact arm is moved to the one circuit position in response to the noted spring bias while the wire material displays a relatively low modulus of elasticity below a transition temperature. The actuator wire is also adapted to abruptly return to its original length and to display a relatively higher modulus of elasticity to move the contact arm to the other circuit position against the spring bias when the wire material is heated above its transition temperature. Means are provided for electrically self-heating the actuator wire to its transition temperature when relay operation is desired.

    Abstract: A miniature remote control circuit breaker in which a movable contact member including a movable contact is engageable with a fixed contact. Motor means, such as a solenoid and an armature actuated thereby, move the contact member from a contacts-open position to a contacts-closed position when the solenoid is energized by remote switch means. Preferably a linkage including two resiliently connected driving members is employed to couple the motor means to the contact member. Condition-sensing (e.g. current-sensing) latch means retain the contact member in its contacts-closed position until the condition sensed varies beyond a predetermined value whereupon the latch means releases the contact member, thereby opening the contacts independently of the energization of the motor means. Further latch means are provided to retain the contact member in its closed position. The latter latch means are responsive to further actuation of the remote switch means thereby to release the contact member and separate said contacts. A further solenoid and armature are preferably provided to effect the release of the further latch means in response to further actuation of the remote switch means.

    Abstract: A circuit breaker comprises a casing, a pair of contacts mounted on the casing, and a member movable between a position bridging said contacts for closing a circuit and a position opening said circuit. The bridging member is adapted to flex to a selected extent in response to a selected current in the circuit and a pair of upstanding arms on the bridging member are adapted to move apart to a selected extent in response to such flexing of the member. First biasing means mounted in the casing bias the bridging member to its open circuit position. A bushing having a central bore is then mounted on the casing, the bore having first and second diameter portions connected by a shoulder within the bore which faces the bridging member. An operating member is slidable in this bore between open and closed circuit positions thereof, the operating member having a recess at one end facing the bridging member and having at least one peripheral aperture opening into the recess. Second biasing means engage the operating member and the bushing for biasing the operating member to its open circuit position. A first latching member has a cam portion slidable in the operating member recess and has a shank portion extending from the recess. A second latching member is slidably mounted on this shank portion of the first latching member; a latching ball is disposed within the aperture opening into the operating member recess and engages the cam portion of the first latching member therein; and a third biasing means engaging the first and second latching members biases the cam portion of the first latching member away from the second latching member. The second latching member normally engages the arms of the bridging member for holding the bridging member in its closed circuit position and for biasing the cam portion of the first latching member to cam the latching ball through the operating member aperture into engagement with the shoulder in the bushing bore to releasably hold the operating member in its closed circuit position. However, the second latching member is adapted to be released from its engagement with the bridging member arms in response to said movement of the arms, thereby to release the cammed engagement of the latching ball with the shoulder within the bushing bore and to permit the operating member and the bridging member to move their open circuit positions in response to said biasing means. Manual force moving the operating member toward its open circuit position also serves to apply a force to the latching ball engaged by the bushing shoulder for camming the cam portion of the first latching member toward the second latching member against the bias of the third biasing means, thereby to permit the latching ball to disengage the bushing shoulder and to permit the operating member and the bridging member to move to their open circuit positions in response to the first and second biasing means.
