Definitions

  • This invention relates to a switch for auxiliary motorvehicle circuits in general, and particularly for the circuits of the so-called courtesy lamps, which term designates herein those circuits which are intended to turn on one or more interior lighting lamps in the passenger compartment or other compartments of motorvehicles which are closed by means of doors or protected by gates, upon opening said doors or gates.
  • pushbutton switches For controlling the foregoing auxiliary circuits, it is current practice to use pushbutton switches the body or base whereof is secured to the uprights, or respectively to the peripheral edge, of the compartment, the movable pushbutton of said switch being engaged by the door hingedly mounted on said upright, or respectively by the compartment gate, while said door or gate are in their closed positions.
  • the pushbutton- has a movable contact which is urged to engage a corresponding fixed contact by the action of a spring, and said contacts are separated, in order to break the circuit electrical continuity, by the action of said door or gate, which move the pushbutton against the bias of the spring.
  • Such switches have some drawbacks, being above all liable to jamming with some frequency owing to the penetration of water and dirt therein, difficult to install, and what is more important, complicated construction-wise, so that their ultimate cost can be considered excessive with regard to their function.
  • the invention sets out to eliminate such drawbacks, by providing a switch -particularly useful for the circuits specified hereinabove -- which is extremely simple, reliable in operation, easy to install, and in particular such that it requires no fasteners, such as screws or the like, of any kind.
  • a switch for auxiliary motorvehicle circuits and particularly for motorvehicle courtesy lamp circuits, characterized in that it comprises a block of an elastomeric material having a lug extension incorporating a substantially C-like metal foil contact, one leg whereof is embedded in said lug extension, the other leg being left uncovered to engage with a ground rheophore, when the lug is not deformed by the door or gate pressure, to close the cir cult, and disengage therefrom when the lug is elasti- eally deformed by the pressure applied by said door or
  • the free end of the contact foil or reed is provided with an extension in the form of a "Faston" connector for receiving a corresponding terminal of the circuit lead,and the elastomeric material block, advantageously formed with a polygonal contour, has a groove adapted for receiving the edge of a corresponding polygonal opening formed in the vehicle body metal sheet.
  • the switch can be quickly and easily installed by deforming the block to engage said edge with said groove, the reverse operation enabling the removal of the switch.
  • this switch comprises essentially a block 10 of an elastomeric material, advantageously of either natural or synthetic rubber, which has a lug extension 11 capable of undergoing elastic fold-over deformation relatively to the block.
  • the lug incorporates one leg 12 of a metal foil contact 12, of substantially C-like configuration; said contact being indefor- mable and advantageously formed from either hard bronze or brass.
  • the other leg 12 b of the contact 12 is free and has an extended end 12c in the form of a connector, advantageously of the "Faston" type, and adapted for receiving a corresponding terminal provided at the end of the circuit lead (not shown).
  • Said free end 12 b of the contact 12 is adapted for engaging a ground rheophore 13, comprising a screw or the like, which is provided in a corresponding seat adjacent the switch, with the lug 11 in the non-deformed condition.
  • a force is applied to the lug which tends to press it onto the block 10 -- that is to fold the lug together on the block -the end 12 b . of the foil contact 12 is caused to rotate and move away from the rheophore 13, thus breaking the circuit electrical continuity.
  • the block 10 is provided with a peripheral groove 10 a adapted for receiving the edge of a corresponding opening 'formed through the metal sheet L of the vehicle body, thereby the switch can be readily mounted and removed by elastically deforming the block such as to mutually engage, respectively disengage, said groove and edge.
  • the contour of the block and corresponding edge are made: polygonal.
