  • the connection possibilities are limited to the diameter of the passage opening.
  • Each terminal is fixed by screws on a transverse partition which does not accommodate a moving pusher or parts supply of a lamp integral with the terminals.
  • the present invention aims to provide units control and / or design signaling monolithic or monobloc and equipped with screw-calipers protected.
  • the arrangement of these units presents Cost advantages and mounting and wiring is easily done.
  • the invention aims in particular to provide switches with contacts double break.
  • the screw terminal unit comprises a one-piece body forming a flange provided with a thread outside allowing mounting by nut on a support and wrapped at the back by a cut-off hood through passage openings of the wiring leads and access to screws whose axes are parallel to the axis of symmetry of the body and is characterized by the fact that the screws cooperate with connection conductive parts folded and held, so eccentric, with respect to the axis of symmetry, in the body, which provides a cylindrical inner housing which is open on the side of the conductive parts in order to allow the passage of at least one pusher of moving contacts or a contact pusher mobile devices and a light component or component luminous.
  • the guide body in translation, in its housing, a cylindrical movable pusher hollow with at least one lateral extension forming a cage in which is mounted a bridge of contacts cooperating with contacts fixed to the parts conductive.
  • the unit has four conductive parts with fixed contacts and the pusher has two side cage extensions for two contact bridges.
  • the unit comprises two conductive parts with fixed contacts and two conductive parts supplying a light component.
  • the unit comprises a cap wrapped around the back of the body and pierced, laterally, by lights allowing the passage of drivers intended to be connected to the terminals and, the back, through openings adapted to the passage of a tool to screw the screws.
  • the control units and / or signaling illustrated by the drawings each comprise a body monobloc 1 plastic centered on an axis X-X '.
  • This body 1 comprises at the front a cylindrical collar constituted, at the front, of a cylindrical part 11 large diameter and, at the rear, a cylindrical part 12 of smaller diameter, these two parts being united by a shoulder.
  • a cylindrical inner bore 13 centered on X-X ' is provided in the body.
  • cylindrical 12 of small diameter has an external thread on which is screwed a nut 31 serving to fix the unit in a wall or table opening.
  • a seal 32 is fitted on the cylindrical portion 12 while being pressed against the formed shoulder by the collar.
  • the control unit and / or signaling comprises conductive parts 6a, 6b, 7a, 7b provided with terminals screwed and held on the body 1.
  • Each piece conductor has a connection range in which have been practiced a repoussage and an opening threaded to receive a through screw head in addition, a clamping bracket associated with it.
  • the screws marked 61a, 61b, 71a, 71b have axes parallel to the X-X 'axis and the screw heads are oriented towards the rear of the unit.
  • Each conductive part is constituted by a blade folded so as to constitute the connection range.
  • the cylindrical bore 13 is open and not partitioned on the side of the conductive parts 6a, 6b, 7a, 7b so to accommodate either a pusher or extensions drivers for a lamp.
  • the body 1 presents behind the flange 11-12, a framework consisting of two longitudinal tie rods 14 joined together by a rear bracing 15.
  • This framework carries the conductive parts 6a, 6b, 7a, 7b according to the versions.
  • stirrup 62a or 62b or 72a or 72b which has a hole for the passage of the screw and has a polygonal or circular outer shape (washer) adapted for mounting in a protective cap 2 which will be described below in detail.
  • the outer form stirrups is octagonal.
  • the control unit providing the switch function comprises conductive parts marked 6a and 6b which carry the stirrups and are equipped with contacts fixed.
  • Each conductive part 6a or 6b has a shape in U of which a branch constitutes a connection range 66a or 66b and whose other branch carries a contact fixed 65a or 65b.
  • the screws 61a and 61b are respectively screwed on the connection pads 66a and 66b.
  • Fixed contacts cooperate with moving contacts mounted on a movable pusher 4 used to maneuver contacts.
  • This pusher is housed in the bore 13 of the body 1 so as to be guided in translation, according to the X-X 'axis.
  • a spring 51 is housed in the annular space between the cylindrical part of the bottom of the pusher 4 and the bore 13. The spring 51 therefore tends to push back the pusher 4 forward to an end position front race, determined by a stop.
  • a seal 52 is housed in a groove ring formed on the periphery of the pusher 4. This seal 52 slides, rubbing, in the bore 13 and ensures sealing.
  • the pusher 4 carries one or two contact bridges 9 equipped with moving contacts cooperating with contacts fixed conductive parts 6a, 6b carrying the screw clamp.
  • Each mobile contact bridge 9 is mounted in a lateral extension forming a cage 42 and integral with the pusher 4.
  • a spring 92 is compressed between the cage 42 and the contact bridge 9 to ensure the contact pressure and allow the deflections of the button.
  • the two conductive parts 6a or 6b associated at the same bridge are turned upside down, so eccentric to a plane passing through X-X '.
  • the extension and the cage 42 of the pusher are eccentric with respect to the X-X 'axis. In particular in lighted versions this provision allows for clear the central space occupied by the power supply from the base outlet.
  • the pusher 4 In the rest position, the pusher 4 is in position before under the action of the spring 51.
  • the contact bridge 9 When pressing the push 4 and the cabochon 44, the contact bridge 9 is moved backwards and the contacts open or close.
  • the unit providing the signaling function comprises conductive parts 7a and 7b which serve for feeding a light component 8 which is housed in the bore 41 of the pusher 4.
  • this component is an Incandescent lamp having a bayonet or screw cap.
  • this luminous component could be a lamp neon or a light emitting diode.
  • the room 7a is provided with a bushing 75 serving to lock the lamp 8 and carry a screw 71a and the associated stirrup 72b.
  • the electrical connection between the second terminal with screw 71 b and the contact which protrudes on the bottom of the lamp base is ensured by the conductive part 7b and via an elastic contact spring 73 which is centered on the X-X 'axis and presses this pad.
  • the conductive part 7a extends away from the axis X-X ' while the contact spring 73 is centered on X-X '.
  • the bushing 75 When the bushing 75 is adapted to a lamp to bayonet, it has grooves adapted to the lugs Lateral of the base. When adapted to a screw lamp, it has an internal thread allowing the screwing of the lamp base.
  • the control and signaling unit of the figures 1 to 4 has a push button switch and a light indicator powered by the screw terminals 71a and 71b.
  • the pusher 4 is closed, at the front, by a cabochon 44.
  • This cabochon is made of plastic transparent, colored or not, fixed, by screwing, on the pusher 4 whose bore 41 which is centered on X-X ' is open on said cabochon.
  • the mobile 4 cylindrical pusher is provided with at least one lateral extension forming a cage 42 in which is mounted a bridge of contacts 9 cooperating with contacts fixed to the parts conductive 6a, 6b.
  • the control unit of FIGS. 5 to 8 presents two conductive parts 6a provided with fixed contacts and two conductive parts 6b each provided with a fixed contact.
  • the pusher 4 has two extensions laterally forming two cages 42 in which are mounted two contact bridges 9.
  • the pushbutton 4 has, at the front, a frontal bearing surface 46 serving as a support key.
  • the two pairs of screw terminals 61a and 61b serve in this case to supply running from both contacts. It will be noted that one contacts is of the "closed" type and that the other is 'open' type.
  • the key 46 is integral with the pusher 4, in the variant of Figure 8, the key 46 is reported and attached to the pusher 4 which allows to change color touch.
