Definitions

  • the present invention relates to an improved toggle switch for industrial motor vehicle applications.
  • the so-called “toggle” switches that is switches in which a driving key supports contact elements provided on an oscillating or swinging movable blade element so as to engage with corresponding fixed contacts arranged at preset positions.
  • toggle switches which can be either of the stable or of the unstable type and can include either two or three working positions
  • the movable contact bearing blade can assume an offset or not proper position, which in turn can cause the generation of sparks with a consequent undesirable oxidation of the contacts.
  • the element provided for causing the blade to swing about its cross axis is usually constituted by a small rod, the sliding of which, along the blade, can be hindered by friction phenomena.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a toggle switch in which the movable blade element is so designed and arranged as to constantly assure a perfect electrical connection between the movable contacts and fixed contacts.
  • a main object of the present invention is to provide a toggle switch including a blade element which is not affected by undesired vibrations.
  • Yet another object of the present invention is to provide such a toggle switch which is very reliable in operation.
  • an improved toggle switch specifically designed to be applied on industrial motor vehicles, characterized in that said toggle switch essentially comprises a blade element which can swing about a cross axis thereof and is held at a set position by a pressing resilient point element, said blade element supporting drum contact elements, made of a metal alloy, a rod element being furthermore provided for tilting said blade element on underlaying fixed contact elements.
  • the improved toggle switch according to the present invention which has been generally indicated at the reference number 1, comprises a box-like body 2 including two longitudinal walls 3 which defines corresponding elongated side compartments 4 and a central compartment 4'.
  • the side compartments are provided with contact elements 5 and include therein corresponding lamp-holder elements 6, of the withdrawing type, whereas the central compartment is provided, at the bottom thereof, with a pair of fixed contacts 7 which are advantageously co-molded with the bottom of the box-like body and consist of pads preferably made of a metal Ag/Ni alloy.
  • the box-like body is extended downwardly by a bottom element 2', which supports reduced-pitch terminals and defines a seat adapted to snap receive a wiring terminal block.
  • contacts 8 which consist of half-cylindrical or drum pads, made of an Ag/Ni alloy, restrained on a movable blade element 9, which is suitably contoured, said contacts 8 being adapted to hold the blade element properly oriented during the tilting movement thereof.
  • the movable blade element in particular, is driven, with a partial turning movement, about its cross axis, by a swinging plate element 10 which, at the top thereof, is provided with a throughgoing longitudinal hole 11 and a central slot 12 which, in turn, extends with a throughgoing hole open at the bottom.
  • This point element in particular, is provided to operate as a position marking element, so as to eliminate possible clearances and vibrations of the blade element; the roller 15, in turn, is specifically designed for reducing the sliding friction of the rod, so as to improve the performance thereof.
  • a dirt cover element 16 which is provided with side openings 17 therethrough the light beams of underlying lamps 14 can pass, and being moreover provided with a central opening 19 which is formed at the slot 12 of said swinging plate.
  • a driving key 20 having a hollow construction, which is provided with a downwardly directed central lug 21 and adapted to engage in that same slot of said plate.
  • the driving key is restrained to the box-like body, as well as to the swinging plate, by means of a pin 22 and that the key is provided, at one end thereof, with an ideogram 23 and, at the other end thereof, with a transparent or translucid portion 24, adapted to signal the closure condition of the switch.
  • the mentioned key will be substantially disengaged from the tilting system, and, accordingly, it can be easily replaced by another key or push-button, of different construction, depending on requirements, without the need of modifying the elements of the tilting system.
  • perimetrical lugs 25 can be provided for abutting against corresponding lugs 26 of the box-like body in order to limit the rotaty movement of the latter.
