Abstract: A hinge for mounting a door on a piece of furniture or the like comprises a hinge arm, a box connected to the hinge arm by an articulation system comprising a plurality of movable connecting levers and seven articulation axes, spring means acting in closing direction of the hinge, and a damping device having an actuation member linearly movable according to a longitudinal axis; the damping device is at least partially enclosed between the side walls of the hinge arm, and the actuation member of the damping device extends at a front end of the hinge arm facing the hinge box for contacting thrust element of one of the connecting levers of the articulation system or integral with one of the connecting levers or with the hinge box at least in a range near the closing position of the hinge.

Abstract: An electrical relay device includes a housing, a wire coil, an actuator assembly, and a shell. The housing extends between a closed end and an open end and defines a chamber. The wire coil and the actuator assembly are within the chamber. The actuator assembly is configured to move between a first position, in which a movable contact is spaced apart from at least one stationary contact, and a second position, in which the movable contact engages the at least one stationary contact, based on a magnetic field induced by current through the wire coil. The shell seals the open end of the housing to seal the chamber. The shell has a pressure relief valve in flow communication with the chamber. The pressure relief valve is configured to open in response to a pressure within the chamber exceeding a threshold set pressure to reduce the pressure within the chamber.

Abstract: A relay includes: a fixed terminal on which a fixed contact is provided; a movable terminal on which a movable contact is provided; a cam that has an elliptical circumference shape, and is rotatable while a portion of the circumference shape is contacting a surface of the movable terminal; and a driving unit that rotates the cam so that respective portions located at one ends of a major axis and a minor axis of the elliptical circumference shape alternately contact the surface of the movable terminal; wherein when the portion located at one end of the major axis of the elliptical circumference shape of the cam contacts the surface of the movable terminal, the movable terminal is deformed elastically so that the movable contact contacts the fixed contact.

Abstract: Included are: a closing spring which provides a closing drive force for closing a contact of a switch device by rotating a camshaft by release of energy; a first semi-circular latch which retains stored energy of the closing spring via a closing lever; an output lever which pivots by being pressed by a cam provided on the camshaft when retention by the first semi-circular latch is released and the energy of the closing spring is released, and transmits the closing drive force to the switch device via a linking mechanism; and a second semi-circular latch which prevents the output lever from pivoting in a tripping direction via a tripping lever and retains stored energy of an interrupting spring provided on the linking mechanism, the pivoting of the output lever being caused by transmission of the stored energy of the interrupting spring.

Abstract: A switch device includes a housing having a receiving portion; an operation member that receives a pressing operation; a plurality of fixed contact points provided in the receiving portion side by side at predetermined intervals; a plurality of movable contact points having contact point portions that come into sliding contact with the fixed contact points; and a snap action mechanism that drives the movable contact points when the operation member is pressed to a predetermined position.

Abstract: A drive mechanism for a circuit breaker or power switch made up of at least one switching unit and comprising a biasing mechanism which can act upon the switching unit, with actuating mechanism for biasing the biasing mechanism, drive mechanism for driving the switching unit under the influence of the energy stored in the biasing mechanism, and mechanism for resetting the switching unit from the driven state. A coupling mechanism in the form of a movement-direction-dependent carrier mechanism is provided whereby the biasing mechanism is brought in its biased state into engagement with the drive mechanism for driving the switching unit and in the driven state of the switching unit the engagement of the biasing mechanism and the drive mechanism is released for resetting the switching unit without operation of the actuating mechanism, and the biasing mechanism and the drive mechanism act upon each other only in the direction of movement opposite to the biasing direction.
