Definitions

  • the present invention relates to an electrical switch with a sealing element, particularly designed for motor vehicle window winders.
  • switches of conventional type is constituted by the fact that the infiltration of dust, becoming deposited on the contacts within the switch itself, can create problems for correctly making electrical contact, with the possibility of failure of operation.
  • Another disadvantage of conventional switches lies in the fact that in the case of the use of the so-called sealed switches, there are significant expenses both as far as their production is concerned and as far as the connection of the electrical conductors is concerned.
  • the object of the present invention is that of eliminating the above-mentioned disadvantages of providing an electrical switch suitable for window winders, with a sealed element which enables the infiltration of dust and the like to be prevented whilst having a considerably simplified structure.
  • a particular object of the invention is that of providing an electrical switch, particularly for motor vehicle window winders, which enables the electrical contacts to be adequately protected from the outside by preventing their oxidation, as well as preventing the deposit thereon of layers of extraneous material which would alter the electrical contact characteristics.
  • the present electrical switch whilst having considerably improved characteristics, is simple and rapid to assemble and connect.
  • Not the least object of the present invention is that of providing an electrical switch which can be obtained starting from commonly available materials and which is competitive from an economic point of view.
  • an electrical switch particularly for window winders with a sealed element, characterised by the fact that it comprises a box-like body to which is connected a pivotal key for the actuation of the electrical contacts, there further being provided a seal having a central body capable of constituting a saddle for housing the pivot pin of the said key and a peripheral projection surrounding the said saddle, whilst the said central body is surrounded by a flanged rim which can be clamped between the said box-like body and an outer frame.
  • the present electrical switch particularly for motor vehicle window winders, which is indicated generally with the reference numeral 1, comprises a box-like body generally indicated 2, in the interior of which there are provided various electrical contacts generally indicated 3.
  • a key 4 which is provided with a pivot pin 5 connected to the box-like body 2 and having an internal prominence 6 for the actuation of the contacts.
  • the peculiarity of the invention is constituted by the fact that a seal, generally indicated with the reference numeral 10, is present, which defines a flat central body 11 in the median portion of which there is provided a saddle 12 where the pivot pin 5 is housed.
  • peripheral projection 13 which surrounds and overlies the saddle 12 and which is provided at the top with a through hole 14.
  • the said peripheral projection 13 can be housed within the key 4 which, advantageously, is made of optically transparent naterial in such a way as to transmit light which is produced by a service lamp 15 provided in the box-like body, thus making the switch easily visible even at night.
  • the central body 11 is provided with a flanged rim 20 connected to the central body 11 by means of a side face 21.
  • the flanged rim 20 can be clamped between the upper end of the box-like body 2 and an outer peripheral frame 23 which can be snap-engaged to the box-like body 2 by the effect of the presence of a tooth 24 defined by the box-like body 2 and a catch projection 25 defined by the frame 23.
  • the region containing the contacts 3 of the electrical switch is sealed separately from the exterior and therefore there is no possibility of the infiltration of dust or other extraneous elements, thus guaranteeing the precise operation of the switch.
  • the switch can be used in a conventional manner and the seal 10 behaves as a resilient element which allows the key 4 to assume all the desired positions.
  • the particular shape assumed by the seal 13 allows adequate sealed isolation of the body of the switch to be obtained with extremely simple means which are assembled easily, thus contributing to a better preservation of the electrical contacts with consequent improved operation.
