  • Patent number: 6998555
    Abstract: An electrical miniswithch comprising a case including a case part forming a base having several electrical terminals extending therefrom, and a case part forming a cover, an instantaneous switching mechanism located in the case and comprising a flexible conducting blade subjected to a substantial pre-stress, and a push-button mounted sliding through the part of the case forming the cover to actuate the instantaneous mechanism. The miniswitch also comprises a compression spring opposing sliding of the push-button so that in the break position of the miniswitch the flexible conducting blade is biased by th push-button and the spring, retained by a stop on the push-button, and in the switched or make position of the miniswitch the conducting blade is not subjected to constraint from the push-button and the compression spring.

  • Publication number: 20050109601
    Abstract: The invention relates to an electrical miniswitch comprising a case including a case part forming a base wherefrom several electrical terminals are salient and a case part forming a cover, an instantaneous switching mechanism placed in the case and comprising a flexible conducting blade subjected to a substantially longitudinal pre-stress, and a push-button mounted sliding through the part of the case forming the cover so as to actuate the instantaneous mechanism. According to the invention the miniswitch also comprises a compression spring opposing sliding of the push-button so that in the break position of the miniswitch the flexible conducting blade is kept biased by the push-button and the spring, by means of a stop placed on the push-button, and that in the switched position of the miniswitch the conducting blade is not subjected to any constraint from the push-button and the compression spring.

  • Patent number: 6518522
    Abstract: A position sensor for sensing the position of a moving part capable of actuating a plunger belonging to the sensor and more specifically a mechanism for orienting the plunger of the sensor. The sensor includes a guide that is rotationally orientable in a body about a first axis XX′ of rotation, and a plunger sliding without rotation in the guide along the axis XX′. A locator prevents rotation of the guide in the body about the axis of rotation, in a given angular position. The locator is fixed nonremovably in the body and possesses either several tabs spaced regularly about the guide and capable of fitting into one position groove to immobilize the guide or several position grooves in which one tab can fit to immobilize the guide. Such a position sensor may find particular application in detecting the positions of moving mechanical components.

  • Patent number: 6396014
    Abstract: A device for amplifying the movement of an operating button of a switch, wherein the switch is fixed in a body of the device. The device includes a pusher that is translatable along an central longitudinal axis of the body. The translation of the pusher constitutes the amplified motion. The device also includes a varying-diameter cylindrical member, and a first support region. The first support region is capable of moving along a ramp of the pusher, when the pusher moves along the central longitudinal axis of the body. The varying-diameter cylindrical member includes a second support region in permanent contact with a region of the body, whatever the position of the pusher, and a third support region in contact with the operating button of the switch.

  • Patent number: 6103983
    Abstract: A mechanism for manually controlling an electric switching member includes a control button, a guide for guiding the movement of a moving element of the switching member, and a link which moves longitudinally in the direction of travel of the control button and laterally into an abutting position which prevents longitudinal movement of the link. The mechanism further includes an element secured to the control button and configured to contact the link to cause the longitudinal movement of the link, a first spring configured to push the control button into a pulled-out position, a second return spring configured to push the link out of the abutting position, and a cylindrical bushing in which the control button slides.

  • Patent number: 5264818
    Abstract: A circuit breaker comprises a lock (12) having a high position when the circuit breaker is triggered and a low position when the circuit breaker is set. The lock in the low position is held by a locking lever (10) against which the lock abuts. The lever cooperates with a device for detecting a current surge which, during a surge, disengages the lever so that the lock no longer abuts against the lever and is released in order to go back to its high position. The locking lever is movable between a high position and a low position, urged to its low position when the lock is set to low position, and associated with upward biasing means active (50) when the lock no longer abuts against the lever.

  • Patent number: 5257001
    Abstract: A circuit breaker comprises a connector (17) connected to a bimetal blade (1) having an adjustable inclination. An end of the bimetal blade is embedded in an isolating axle (2) parallel to the plane of the bimetal blade (1), the position in rotation of the axle being adjustable by a screw (5) parallel to the axle comprising a tapered tip pressing on a lever (4) fixed to the axle (2) and perpendicular to the latter.

  • Patent number: 5128647
    Abstract: A hand-controlled breaker comprises a housing (1), a control button (12), and a control bar (21). Two rods (15, 15') are mounted so as to pivot inside the control button, and extend downwardly outside the control button towards the cavity of said housing. Each rod comprises an oblique supporting surface (17, 17') oriented in an inward and downward position, and a second lower oblique supporting surface (19, 19') oriented in an inward and upward position. The four supporting surfaces surround and maintain a cylindrical part (20) coupled to an upper portion of the bar (21). The rods each further comprise an oblique supporting surface (58, 58') outwardly and upwardly directed to against a lower edge of a bore (10) of an upper portion (4) of the housing.

  • Patent number: 4684770
    Abstract: A microswitch comprises a compression spring abutting onto an insulating base which supports conducting terminals, the spring exerting indirectly a permanent tension force on flexible lateral arms of a blade pivotably mounted on one of the terminals with its free end being movable between the other terminals. The tension force is exerted via a pivoting point on an oscillating lever guiding an applied control force and sliding on the insulating base by one of its ends which is opposite another of its ends which pivotably mounts the lateral arms of the blade and which applies the tension force of the compression spring thereto.
