- the invention aims to remedy these drawbacks.
- the invention provides a lateral actuation switch of the type mentioned above, characterized in that it comprises an actuation lever mounted articulated relative to the support about an axis parallel to the bottom of the housing, one point of which support cooperates with the trigger member and the point of application of the driving force by the pusher cooperates with a portion of the pusher in the form of an inclined ramp, and in that the lever is resiliently returned to its rest position .
- a contact carrier 10 which, according to a known design, consists essentially of a body or housing 12 made by molding in insulating plastic material and rectangular rectangular shape.
- the body 10 is delimited by lateral faces 14 and 16, by a lower face 18 and by a horizontal upper face 20 in which a housing 22 opens.
- the housing 22 is delimited by a peripheral wall 24 of rectangular outline and by a bottom 26 which is substantially planar and parallel to the upper face 20.
- the body 12 is produced by overmolding on two conductive elements.
- a first conductive element has a connection end 28, which extends outside the body 12 from a side face 16, to allow mounting of the switch on a printed circuit board (not shown), for example according to the technique of the flat transfer of the components, and comprises a fixed contact end 30 which is arranged in the bottom 26 of the housing 22 substantially in the center of the latter and slightly in relief relative to the bottom 26.
- a second conductive element has a connection end 32 and a fixed contact end 34 arranged in the bottom 26 in the vicinity of the wall 24 and in relief relative to the plane of the bottom 26.
- the housing 22 is dimensioned to receive a triggering member 36.
- the member 36 is, according to a known design, an element of conductive material of generally domed shape which bears against the bottom 26 by its lower lateral edge 38 of rectangular outline and whose central apex 40 extends above the contact fixed 30.
- the triggering member 36 is supported by its edge 38 on the fixed contact 34 and on a raised part 35 of the bottom 26 of the housing 22 located substantially at the same altitude as the fixed contact 34.
- the concavity of the triggering member 36 faces the bottom 26 and the member is capable of being deformed, against its own elasticity, according to a vertical tripping direction V, to establish an electrical connection between the fixed contact 30 and 34.
- the tripping member changes state suddenly, beyond a determined tripping stroke, so as to transmit to the user a tactile sensation of its triggering.
- the height of the member 36 is less than the depth of the housing 22 and the latter is covered by a protective and sealing film 42 which covers the upper face 20 of the support 12.
- the film 42 is made of flexible material so as to allow it to act on the member 36, the film further comprising an adhesive face ensuring its sealing with the upper face 20, and therefore the sealing of the housing 22 in which is disposed. the trigger 36.
- Means for actuating the member 36 consisting essentially of a pusher 44 for actuation and by a control plate 46 comprising a control lever 48 are interposed between the pusher 44 and the triggering member 36.
- the control plate 46 is a metal plate produced by cutting and folding and whose rectangular outline is substantially the same dimensions as those of the support 12.
- the plate 46 is delimited by lateral edges 50 to 54 and it has a central hole 56 which extends to the right and above the domed central part 40 of the triggering member 36.
- the plate 46 In the vicinity of its lateral edge 52, the plate 46 comprises a stop tab 58 which is folded vertically at a right angle above the upper face 60 of the plate 46.
- the tab 58 extends in a median vertical plane P which is the plane of symmetry of the design of the switch, with the exception of the arrangement of the fixed contacts 30 and 34 (see FIG. 3).
- the plate 46 In the vicinity of its lateral edge 50, opposite the edge 52, the plate 46 has two opposite guide tabs 62 which extend above the upper face 60 and which are arranged symmetrically on either side of the plane P.
- control plate 46 comprises a control lever 48 produced integrally with the plate 46.
- the lever 48 is produced in the form of an elastically deformable blade comprising a fixing section 64 and an active section 66 with which the pusher 44 cooperates and which is designed to act on the triggering member 36.
- the connecting section 64 has a profile substantially in the form of a capital U lying horizontally parallel to the plane of the plate 46.
- the section 64 comprises a first rectilinear branch 68 which belongs to the body of the plate 46.
- the rectilinear branch 68 is extended by the bent branch 70 which extends above the upper face 60 and substantially in line with the lateral edge 50.
- bent part 70 is made possible by two short slots 72 which extend, parallel to the plane P, from the edge 52.
- the section 64 comprises a second rectilinear branch 74 parallel to the branch 68 and which is extended by the active section in the form of a loop 66.
- control blade to behave more or less like a recessed beam capable of bending transversely to constitute a lever pivoting about an axis XX located substantially in the connection zone between the branches 70 and 74.
- the axis X-X is substantially parallel to the upper face 60 of the plate 46 and perpendicular to the horizontal direction H of lateral sliding of the pusher 44.
- the active part 66 is a loop comprising a first curved portion 76, starting from the branch 74, the convexity of which is provided to cooperate with the pusher 44 and to constitute the point of application of the actuating force on the lever 48.
- the active section 66 comprises a second curved portion 78 arranged opposite the hole 56, in the plane of the plate 46, and which constitutes the fulcrum of the lever 48 capable of cooperating with the central part 40 of the triggering member 36.
- the loop 66 ends in an end edge 80 arranged substantially opposite the face 75 of the branch 74 and close to the latter.
- the pusher 44 is a molded plastic part of generally rectangular parallelepiped shape which is delimited by a lower face 82 which bears on the upper face 60 of the control plate 46, a parallel upper face 84, two longitudinal lateral faces 86, by a lateral actuating face 88 and by an end face 90.
- the width separating the faces 86 is such that the body of the pusher is guided in sliding between the guide tabs 62 of the plate 46.
- the end portion 90 of the pusher 44 has a through central notch 92 which is delimited longitudinally by a ramp 94 inclined at approximately 45 ° and which is designed to cooperate with the curved portion 76 of the loop 66 of the lever 48.
- a longitudinal groove or slot 96 is formed in the lower face 82 of the pusher 44 and it receives the stop tab 58 of the plate 46.
- the groove 96 is delimited longitudinally by an end edge 98 with which the tab 58 is in abutment to define the rest position of the pusher 44 towards which it is resiliently returned by the lever 48 which acts on the ramp 94.
- the groove 96 is also delimited by its opposite edge 100 with which the tab 58 cooperates to limit the actuating stroke of the pusher 44, from right to left by considering the figures.
- All of the components 10, 42, 46 and 44 are kept stacked vertically and assembled by a cover 102 produced in the form of a piece of cut and folded sheet metal.
- the cover has a flat, full and rectangular horizontal top wall 104 which extends above the upper face 84 of the pusher 44 and above the plate 46.
- the upper wall 104 is continuous and it allows easy gripping, for example by suction, of the switch for its precise and automated positioning on a printed circuit board, and this despite the very small dimensions of the switch.
- the wall 104 is extended vertically by two longitudinal side walls 106 which extend opposite the edges 54 of the plate 46 and opposite the lateral faces 16 of the contact carrier.
- the upper wall 104 is also extended by two transverse vertical side walls 108 which extend in facing the edges 50 and 52 of the plate 46 and facing the lateral faces 14 of the contact carrier 10.
- the walls 108 each have a central cutout 110 for the passage of the body of the pusher 44, which extends vertically to the lower edge 112.
- the vertical and parallel edges 114 of the cutout 110 are also cut out to form two pairs of lugs 116, 118 which are slightly folded transversely towards the inside of the cover 102.
- the lower lugs 118 make it possible to crimp the cover 102 in the position mounted on the contact carrier 10 whose body 12 has, in its lateral faces 14, notches 120 which receive the lugs 118.
- the lower edges 122 of the tabs 116 cooperate with the portions facing the upper face 60 of the plate 46 to keep the latter pressed vertically against the upper face 20 of the body 12, with the film 42 interposed.
- the user acts on the pusher 44 by directly or indirectly applying to it an actuating force on its face 88 in the lateral sliding direction H, from right to left.
- the pusher 44 slides to its release position illustrated in FIG. 6.
- the blade 48 deforms elastically and the curved section 78 moves vertically, in the direction V and through the hole 56, to act on the central part 40 of the dome 36.
- the action on the triggering member 36 causes the change of state illustrated in FIG. 6 in which it establishes an electrical connection between the fixed contacts 30 and 34 with a strong transmission of the tactile effect due to its sudden change of 'state.
- the actuation overtravel therefore does not cause deterioration of the member 36 because the loop 66 has a specific capacity for elastic deformation.
- the blade 48 restores the energy it has stored during actuation to return to its resting state, by pivoting generally around the axis XX in the anti-direction hourly, and to push the pusher 44 from left to right due to the arrangement of the ramp 94.
- the design of the switch according to the invention is particularly compact.
- its total height is less than about 1.7 mm and its width in the direction H, is less than 3 mm.
- the assembly of the components and the relative positioning of the mobile elements are particularly simple due to the design of the control plate 46.
- the central part 40 of the triggering member 36 can be curved to present a profile complementary to that of the curved section 78 of the blade 48.
