Abstract: A pulsed electrical remote control interface for an equipment item including a plurality of functions to be controlled includes at least a first command input associated with a first command line (TC-Type, TC-Type-plus, TC-Type-minus) for selecting at least one function (RF ON, RF OFF, ALC ON, ALC OFF, FCA UP, FCA DOWN, GCA UP, GCA DOWN, SCA UP, SCA DOWN, INHIBIT) to be performed from the plurality of functions and at least one second command input associated with a second command line (EXE, EXE-UP-ON, EXE-DOWN-OFF) for executing the selected function, each command input being associated with an outbound pulsed command line and a return line, the return line possibly being shared with a number of outbound lines. Applicable to the control of any kind of equipment that includes a large number of functions and requires a large number of pulsed command signals, notably in the field of satellite communication systems.

Abstract: A contact pole interrupting device in an electrical switching apparatus composed of a moving contact holder including a cylindrical contact pressure spring, a slide that moves along a longitudinal axis, and a mobile bridge supporting two mobile contacts. The mobile bridge has a central opening in which are inserted two protuberances belonging to the slide and equipped with an outer pin enabling the slide to be clamp-mounted on the mobile bridge. An end of the spring, which rests on the mobile bridge, is kept in a place by a flange on side ends of the slide and is centered by the protuberances of the slide.

Abstract: This invention regards a contact pole interrupting device in an electrical switching apparatus composed of a moving contact holder 10 comprising a cylindrical contact pressure spring 15, a slide 20 that moves along an axis X and a mobile bridge 30 supporting two mobile contacts 41. The mobile bridge 30 has a central opening 33 in which are inserted two protuberances 22 belonging to the slide 20 and equipped with an outer pin 34 enabling the slide 20 to be clamp-mounted on the mobile bridge 30. A end 16 of the spring 15, which rests on the mobile bridge 30, is kept in place by a flange 28 fitted on the side ends 25 of the slide 20 and is centred by the protuberances 22 of the slide 20.

Abstract: A contact-unit slide for contractors which includes an insulating body in which windows are drilled wherein in each of these windows a contact bridge and a compression spring associated with the contacts are housed, the slide being moved by the mobile parts of the contactor's electromagnet, the spring bearing on the opposite side of the support surface adjacent to the contact bridge. The body has slots extending between a window and a visible surface to allow it to be supported on the upper end of the associated spring.

Abstract: An electromagnetic switching device including, in an envelope formed by a base (1) and an insulating casing (7), a contact holder (3) in which are housed contact bridges (4) featuring a moving lock (8) capable of immobilizing the contact holder (3), wherein the lock (8) and the insulating casing (7) have sliding assembly devices (74, 75) which move the lock (8) positively from the rest position towards the contact holder (3) in the locked position by moving the insulating casing (7) away from the base, and the sliding assembly devices (74, 74) move the lock (8) away from the contact holder positively from the locked position by moving the casing towards the base.

Abstract: Connection block for connecting cables (5, 6) to electrical equipment (2) comprising at least one connector (4) consisting of a cage (42) and a wire clamp slide (43) moved by a clamping screw (44) under a compartment (37, 38) in a box (31) in which said connector is placed, characterized in that the slide (43) is U-shaped with one flange at the same level as the screw head (44), and that this flange has a mobile insulating protective cover (35) on its front which follows slide movements and provides access to the screw head.

Abstract: An electromagnetic contactor device including an enclosure formed by a base unit and a housing unit assembled together and accommodating the power poles and a solenoid having a coil the body of which has power supply terminals on one side, said enclosure providing between the base unit and the housing unit a housing adapted to receive the power supply terminals, characterised in that the enclosure has symmetrically disposed relative to the first housing a second housing also formed between the base unit and the housing unit and having substantially the same cross-section as the first housing so that it can receive the side of the coil provided with terminals after the coil is turned around, the housing opposite that receiving the terminals being closed off.

Abstract: A protected electric switching apparatus is provided and its fixing device, comprising a contactor with a latch for engaging a profiled rail and with which a removable thermal relay is associated by means of conducting pins. A channel is formed between two opposite walls so as to allow a screwdriver to have access to an eye of this latch.

Abstract: A thermal relay is provided comprising, in a first cavity of a case, bi-metallic strips through which pass currents of a multi-phase network feeding a load through an electromagnetic contactor and, in a second cavity, an electromagnetic sub-assembly including break and signalling switches whose mobile contacts have pivoting axes and actuating points cooperating with a common piece, the whole forming a deformable parallelogram. The second cavity also contains toggle transmission means between the bi-metallic strips and said common piece as well as means for selecting the mode of operation of the switches. Toggle springs are associated with said mobile contacts.

Abstract: A symmetric percussion switching device is provided using a bistable dead point over-run device including an actuator movable between at least two positions and a control member whose movement causes rocking of the actuator from one to other of the two positions, after passing through the dead point, said device further comprising two switches whose actuating members cooperate with the actuator, respectively in the fractions of the stroke thereof adjacent said positions, said switches then being actuated by percussion so that the drawbacks of the conventional switching devices of this kind are avoided in which the pressure of the mobile contact on the fixed contact is substantially zero in the vicinity of the dead point changeover.

Abstract: A device is provided for adjusting the relative position of two parts of the same piece by deforming an intermediate zone connecting these two parts together, by means of a conical screw, and having a tapped bore in which said screw may be screwed, and a cut out which extends from a first edge of the piece to said bore, wherein said intermediate zone further includes at least a second cut out opening into said bore, opposite said first cut out which defines with a second edge of the piece a deformable zone, forming a hinge, offset with respect to said bore.

Abstract: The invention provides a device for selectively preventing actuating modes of a manual control member equipping the face of the case of an apparatus and able to change over from a first position corresponding to a first function, to a second position corresponding to a second function and, from the first position to a third position corresponding to a third function. It includes a cover mounted for pivoting on the case and able to be applied against said face. This cover allows manual access to said member and includes means for allowing this member to change over from the first position to the third position and preventing it changing over from one to the other of the first and second positions.
