Definitions

  • the present invention relates to a switch, closed in the rest position, and opened by tilting a movable part against a return spring.
  • a switch is usually used to control the correct positioning of a movable member with respect to a fixed assembly, by opening an electrical control circuit on which said switch is interposed.
  • a rocker switch comprising a fixed part on which a movable part is articulated, a return spring tending to bring the movable part into a closed position of an electrical circuit and itself ensuring the closure of at least one electrical circuit, by abutment on at least one fixed contact.
  • the fixed part consists of a housing in two parts which are assembled by trapping between them a panel on which they are mounted and which of course includes an opening intended to receive the housing. The latter is open on one of its faces to receive the movable part of the switch, articulated in delimited bearings, respectively, in the two parts constituting the fixed housing.
  • this known switch In its stable position, to which the spring returns it, the movable part of the switch projects almost entirely from the housing; it only enters it when it is requested by the movable member whose position is checked. Since it is necessary to provide clearances between this mobile part and the fixed housing, the interior of the housing is accessible to the surrounding atmosphere and the contacts are therefore imperfectly protected.
  • this known switch is designed to be fixed to a panel, with a visible part, mainly constituted by the movable part and the frame of the opening made in the housing. The remaining part of the housing, located behind the panel, is not visible and is therefore not treated so as to be aesthetic. Finally, in use, this non-visible part is not accessible so that disassembly of the switch is awkward.
  • the object of the invention is to provide a switch which is particularly inexpensive, robust, the contacts of which are well protected and which can be mounted, either by one or the other of the two opposite faces, so as to be able to be used to operate in two symmetrical positions with respect to each other.
  • the subject of the invention is therefore a tilting switch comprising a fixed part on which a mobile part is articulated, a return spring tending to bring the mobile part into a closed position of an electrical circuit and itself ensuring the closing of '' at least one electrical circuit, by abutment on at least one fixed contact, characterized in that the movable part consists of a hollow plastic body, formed by two half-housings enclosed by elastic engagement one on the other around two pins provided on the fixed part and pierced with orifices allowing the passage of a fixing member, the spring being disposed in said movable part.
  • the switch shown therefore includes a fixed part 1 and a mobile part 2.
  • the fixed part 1 has a central wall 3, two cylindrical pins 4 and two lateral flanges 5. Holes 6 provided in the flanges and the pins allow the passage of a fixing screw 7.
  • the movable part 2 is formed of two half-housings 10, 11 connected by a hinge 12 made of material constituted by a thinning of the wall of the half-housings.
  • the two half-housings close one on the other, around the pins 4, along a joint plane 13, to form a hollow body. Maintaining the closed position is ensured by elastic engagement of a lug 14, carried by the half-housing 10, between ribs 15, 16, 17 carried by the half-housing 11.
  • a return spring 18 has two windings 19 of opposite directions around the screw 7. These windings are separated by a loop 20 intended to cooperate with the contact pads 8. The ends 21 of the spring are engaged in housings 22 formed in the wall 3.
  • the end of the loop 20 is disposed between the rib 15 and the bottom of the half-housing 10 and the force exerted by the spring on this rib 15 tends to keep it in abutment against the contact pads 8. In this position, two electrical circuits independent of each other are closed by return of the current to ground through the screw 7 and a support 23 on which the switch is fixed.
  • the flanges 5 carry protuberances 25 making it possible to precisely position the switch relative to the support on which it is fixed.
  • the switch which has just been described can, for example, be used to check the correct closing state of a motor vehicle door.
  • Fig. 4 shows such an application example, the switch being fixed and positioned with respect to a keeper 26 and its tilting being caused by the housing 27 of the lock mechanism, when the bolt 28 is fully engaged on the keeper.
