Definitions

  • the invention relates to electrical push-button switches with a blistering cup-shaped elastomer return membrane used in numerous fields, in particular in small electronic equipment. These switches known from DE-A-3 307 659 or GB-A-2 039 417 are monostable.
  • the object of the invention is to improve switches of the kind in question in order to avoid the drawbacks just mentioned.
  • Known switches comprise a blistering return elastomer membrane in the form of a cup which carries a movable electrical contact and which is interposed between the push button and the body provided with a corresponding fixed contact.
  • a switch according to the invention further comprises at least one additional snap-back diaphragm, without electrical function, also interposed between the push button and the body of the switch, and located in the same plane, or substantially in the same plane. , that the membrane carrying the electrical contact, between the push button and the body of the switch.
  • the bistable electrical switch shown in FIGS. 1 to 4 comprises a body in the form of a housing I made of insulating material.
  • this switch is double and each of its two similar parts has a control push button 2 also made of insulating material which can slide in the body and passes through an opening 3 of the latter.
  • the inner face of the push button has a recess 4, the bottom of which bears against a boss 5 belonging to a pallet 6 which is part of a mechanism for holding the bistable switch in the latching position; this mechanism is of any suitable conventional type, it will be described a little more in detail below, but it is not, moreover, part of the invention.
  • This membrane comprises a first central blister 13 which exerts, both an electrical function and a mechanical function for recalling the push button, and two additional blisters 14, 15 arranged symmetrically, on either side of the first central blister 13 and playing only a purely mechanical role. reminder of the push button.
  • the three blisters 13, 14, 15 came from molding together during the manufacture of the membrane 12, in one piece, the two additional blisters 14, 15, being located in the same plane, or substantially in the same plane as the central blister 13.
  • the central blister 13 is cup-shaped, the dome of which has a recess 18 on top; the upper edge of this recess bears against the underside of the pallet 6.
  • This blister has a shape of revolution around a geometric axis 19 and it is located below the center of the underside of the push button, of which it contributes to ensure the return to the high position via the pallet 6.
  • a movable electrical grain constituted by a conductive pad 21, made of metal or of conductive silicone, is fixed, by any appropriate means such as crimping, clipping, or bonding , against the central part of the inner face of the cup 13, it is intended to come to bear against a printed circuit deposited on the bottom 11 of the housing.
  • the length of its stroke is indicated in C1 in Figure 2.
  • Each of the two lateral blisters 14 and 15 is of generally frustoconical configuration, the upper part of which is reinforced by a cylindrical part 25 and by a buffer 26 intended to come into abutment against the bottom of the housing at the end of the travel of the push button; the stroke of the buffer 26 is designated by C2 in Figure 2; it is greater than the stroke C1 of the movable electrical grain 21, so that, in the last part of the push-in stroke, from the moment when the movable contact touches the fixed contact at the bottom of the housing, the upper part of the central blister 13 is deformed, which can be done easily, in particular thanks to the presence of its recess 18.
  • the heart-shaped cam 33 occupies its position high and the adjacent end of the lever 35 is at the entrance to the corridor 36 of the heart-shaped cam, as shown in the lower part of FIG. 4. If the push-button 2 is pressed, it is therefore pressed the pallet 5 and the heart-shaped cam 33 descends with it while the lever 35 rises relatively in the passage 36 of the cam, then in the branch 37; when you stop pressing the push button, the elastic membranes make it go back up, but the lever 35 hangs at 35A on the top of the rest 39 of the cam preventing the pallet from going up again, so that the movable contact 21 remains pressed against the fixed contact.
  • FIGS. 5 and 6 a variant of an additional blistering elastic diaphragm has been shown, usable in a movable switch, that is to say a switch which does not include the paddle or the mechanism associated with cam. in the heart for maintaining contact in the active position.
  • This membrane, designated by 24, is of annular shape of revolution and arranged coaxially around the membrane with electrical function 13 in the form of a cup. All of these two membranes could also be manufactured in one piece by molding.
