Abstract: A switching device includes two or more switching modules (7, 8, 15) with at least one switch and connection clamps (24), an actuator (16), and a transfer device (39). The transfer device (39) propagates the drive motion initiated by the actuator (16) in a direction perpendicular to the axis of the actuator (16) and transfers the drive motion to at least one switching pin (18, 19) of the switching modules (7, 8, 15). The switching pin (18, 19) is positionable axially at a distance parallel to the axis of the actuator (16).

Abstract: A make break switchgear includes a first breaking lever receiving a torque in a counterclockwise direction, a second breaking lever connected through a linkage to the first breaking lever, and a making lever receiving a torque in a clockwise direction. These elements are supported by a main shaft and are rotatable. When a circuit is completely opened by the switchgear, a guide guiding a rotor on an arched surface is engaged with a first releasing latch. It is unnecessary to wait for engagement between the first releasing latch and the guide after the circuit is closed for opening the switchgear, and a subsequent opening can be immediately started. Therefore, it is possible to reduce the time from the closing of a make break contact to starting of the next opening.

A clutch gear is connected to the operating handle to be interposed between the operating handle and the rotating gear, and has a second engaging device. An idle stroke is formed such that when the circuit breaker is turned on, the operating handle runs idly after rotation of the operating handle has been started and before the second engaging device engages the first engaging device to drive the rotating gear for actuating the toggle gear.

Abstract: A device for controlling a breaker comprising a weight (48) provided in the vicinity of a releasing trigger (19) and an auxiliary spring (50 )for urging the weight (48) so that the weight (48)is in contact with the releasing trigger (19). An equivalent mass of the weight (48)is about one-third of an equivalent mass of the releasing trigger. When the releasing trigger (19)is in contact with a pin (45) of a releasing latch (18), the weight (48)rebounds but the releasing trigger (19)is settled without rebounding. By such a structure, the rebound of releasing latch and the releasing trigger is prevented when these are engaged, whereby a time for closing a circuit is shortened.

Resilient deflection of the depressible surface causes the projection to come into contact with the electrical contacts, thereby making an electrical connection between them.

Abstract: A spring drive mechanism for switchgear, in particular for a circuit breaker. The mechanism has an engagement shaft that is rotatable about its axis, a large toothed-wheel mounted on said shaft, a small toothed-wheel meshing with said large toothed-wheel to put an engagement spring under stress, and a mechanism which prevents the large toothed-wheel and the small toothed-wheel jamming each other mutually after the shaft has been released. The mechanism which prevents jamming includes the shape of the teeth of said small toothed-wheel and the shape of the teeth of the large toothed-wheel. In the teeth of the large toothed-wheel there is a first gap followed, in the direction of rotation, by a first retractable tooth that is retractable along the axis of the tooth against bias from a spring. This tooth is followed by a second gap extending over a length that is not less than two gear pitch steps and is slightly less than an integer number of steps.

Abstract: A spring drive mechanism for power switch gear. The mechanism includes an engagement shaft free to rotate about its own axis and carrying both a large toothed wheel and a cam. An engagement spring constituted by a traction spring is coupled to the large toothed wheel at an attachment point by a chain. The large toothed wheel meshes with a small toothed wheel which is coupled via a gear train to a driving gearwheel secured to an outlet shaft of a drive motor. In the predetermined direction A of rotation, the large toothed wheel includes a discontinuity in its teeth, thereby generating a gap which constitutes a zone without teeth, and in which a retractable tooth is disposed. Following the retractable tooth, the large toothed wheel has an additional discontinuity in its teeth over at least two meshing steps. This mechanism is advantageous as switchgear for a circuit breaker.

Abstract: A switch mechanism for electrical service quick connect/disconnect, especially suitable for electric vehicles. The switch mechanism includes a handle for turning a shaft which, through a lost motion connection, rotates a gear in engagement with a rack. The rack moves the switch contacts from a disconnect to a connect position to make and break electrical connection between the vehicle battery pack and the vehicle electrical system. An over center device biases the handle into either a full connect or a full disconnect position once the handle passes an intermediate position. A spring forces a locking detent into a notch on the rack to prevent inadvertent movement of the rack from the connect position, and a cam mounted on the shaft actuates a cam follower portion of the locking detent to move the locking detent out of the notch and allow the rack to move to its disconnect position. Further springs are compressed in response to movement of the contacts to their connect position.

Abstract: A suspend (sleep) switch for a portable electronic device, such as a notebook computer, is mounted on a printed circuit board. The suspend switch includes a first contact which is positioned in juxtaposed relationship with a second contact. The contacts are formed from an electrically conductive metal or other electrically conductive material which is sufficiently resilient to support an actuator and to hold the two contacts apart in normal operation.

When the cover of the electronic device is closed, the actuator pushes the two contacts into electrical contact, preferably with a wiping motion, to provide an electrical connection which can be sensed by circuitry on the printed circuit board.

Abstract: A spring drive for an electrical switching apparatus has a switch-on shaft to which a switch-on spring is coupled eccentrically and on which a large wheel (16) is seated in a rotationally fixed manner. A small wheel (20), which is driven in order to stress the switch-on spring, interacts with the large wheel (16).
