Description

The present invention relates to an electrical switch, particularly to

  a plastron switch, of the type comprising a casing, a front plate or front plate provided with at least one operating button, and fasteners for fixing the switch to a support. Already known in the state of the art electrical switches type plastron which attached to a support in that the support

  presents a corresponding opening in which the

  mutator, which is a single block, is embedded by a face.

  This known construction has the disadvantage of a limited mounting possibility. Moreover, he is very

  difficult to equip later, for example a vehicle

  the automobile, of such a plastron switch, this because of the poor accessibility of the corresponding support,

  for example the interior trim of a side door.

  The object of the invention is to construct a

  controller, in particular a switch of the bifurcated type, in a manner which simplifies the assembly and

  to equip such a switch at a later date with

  already existing, such as, for example, that of a

car hicle.

  According to the invention, this problem is solved by the fact that the casing and the plastron are distinct elements, that the plastron is disposed on a first face of the support and the casing on the opposite face, and that

  these two elements are assembled by the fixing

  tion. This construction provides the advantage of ensuring a simplification of the assembly thanks to the fact that the plastron and the boot are attached to the support, the first on a

  face and the second on the other side. This also allows

  to subsequently equip a switch according to the

  an existing installation. Moreover, it is no longer necessary to give the opening of the support dimensions large enough to be able to engage

  the entire box through the opening of the support.

  According to another characteristic of the invention

  the facade plate carries at least one hollow stud which passes through an opening of the support and which can be housed in a complementary cavity formed in the housing, a screw threaded through the hollow nipple screwing into said

  complementary cavity to form a fastener.

  In this way, a new simplification of the

  according to another feature of the invention

  The hollow nipples of the plastron can be used as drilling templates for the formation of corresponding openings in the support. This characteristic

  also helps to simplify the assembly.

  According to another characteristic of the invention

  tion, the switch may comprise a maneuvering rod with a thread, which protrudes from the housing and passes through

  an opening of the support and on which the button of

  workpiece, spring loaded, can be screwed. Moreover, it is

  possible to equip the plastron switch with an invert-

  which can be fitted and fixed on a maneuvering rod.

  protruding from the housing and passing through an opening

support.

  According to another characteristic of the invention

  In addition, said complementary cavities with which the hollow studs of the front plate cooperate cooperate are provided in spans formed on the housing. Other features and benefits of

  the invention will become apparent during the description which

  go follow. In the attached drawings, given solely for the purpose of

For example:

  FIG. 1 is a side view of a switch

  plastron electric device according to the invention provided with an invert-

  before assembly, the view also showing the sup-

sectional port;

  Fig.2 is a front view of the form of

  use of Fig. 1; FIG. 3 is a top view of the front plate and switch housing of FIG. 1

  FIG. 4 shows a side view of a

  platers according to the invention without inverter, before mounting on a support; Fig. 5 is a front view of the embodiment of Fig. 4;

  FIG. 6 is a view from above of the plastics

  tron of the embodiment of Fig.4.

  The switch 1 shown in FIG. 1 consists of a case 3 and a breastplate 4, and this is

  attach it to a support 2. To this end, the front plate 4 pre-

  several hollow nipples 6 arranged at a certain

  mutual support, while box 3 includes several

worn 7.

  Each of the spans 7 is provided with a cavity, not

  represented, complementary to a nipple.

  The housing 3 and the plastron 4 are therefore constituted by distinct elements, the plastron 4 being placed on one side of the support 2 and the casing on the other side of

this support.

  The support 2 has openings 5 in number corresponding to that of the hollow studs 6. The hollow studs 6 can be used as drilling templates for the

  openings 5. On the other hand, the

  still feels an opening 15 and an opening 16.

  For assembly, the plastron 4 is applied to the upper face of the support 2 so that the hollow studs 6 engage through the corresponding openings 5 of the support 2. Then, the housing is applied against the lower face of the support 2, the bearing surfaces 7 provided with said complementary cavities being placed in coincidence with the apertures 8 (FIG. 3) of the hollow studs 6. Now, through the slots 8, hollow studs of the domed and countersunk sheet metal screws, which are number of four in

  example, and they are screwed into the cavities

  in the staves 7 of the casing 3. After this assembly, the operating rods 10 and 13 protrude

  on the top of the case and through the openings

  corresponding headings 15 and 16. Next, screw the

  maneuver 12 overcoming the action of a compression spring 11, then the inverter 14 is mounted on the rod 13 and is fixed on this rod. This operation completes the assembly, after which it is only necessary to connect the contact carrier 9 of the housing 3 to the corresponding electrical components. In Figs. 4, 5 and 6, there is shown

  another embodiment of plastron switch 1 '.

  This exemplary embodiment does not include an inverter. Here too, the switch 1 is in two parts, the housing

  3 and the plastron 4 constituting two parts or parts

separately.

  The plastron.4 has four nipples -

  6 in which are formed respectively

  8 as shown in Fig.6. These hollow studs 6 provided with their lights 8 cooperate with the complementary cavities formed in the staves 7 of the

  prescribed manner, so that here also, after the

  floor, the front plate 4 and the housing 3 are correctly

  support 2 by the countersunk head screws and

  curved which serve as fasteners.

  The particular construction of the switch, which comprises a housing 3 separated from the plastron 4, ensures a

  simplification of assembly and provides the possibility of

  after the event, for example a motor vehicle, with the plastron switch according to the invention. The fact that the plastron 4, with its hollow nipples 6, can at the same time

  serve as a drilling template for the formation of openings

  res 5 in the support 2, ensures a new simplification of the assembly. For example, in the case where the switch according to the invention is later reported on an already existing installation, the assembly can be carried out as follows: using a drill known per se, the holes are drilled 5 , 15 and 16 in the support 2, that is to say for example, in the casing of the door or in the center console of a motor vehicle. Then, the switch can be mounted in a very simple way, without, despite the rectangular shape of the switch, it is necessary to mill or cut openings

  square or rectangular in the support, which leads to

would be expensive.
