Definitions

  • the present invention relates to a switch structure, for motor vehicle electrical window winders.
  • electrical window winders for motor vehicles are provided with an electric motor which controls the raising and lowering of the windows in a manual or automatic manner according as a complete raising is attainable by maintaining the pressure on the actuating push-button or simply by means of an impulse.
  • Switches currently utilised to effect the control of the motor are generally of rather complex structure and, moreover, are subject to frequent breakdowns because of the inevitable infiltration of dust or water into the body of the switch, with the possibility of creating variations in the perfection of the necessary electrical contacts.
  • the object of the invention is that of eliminating the above-mentioned disadvantages by providing a switch structure, particularly for electrical window winders, in which there will be the possibility of providing contacts in an effective and secure manner with a reduced number of component elements.
  • a particular object of the invention is that of providing a switch structure for electrical window winders which is perfectly isolated from the exterior thus preventing the infiltration of dust and water with a consequent significant improvement in the precision of operation of the switch itself.
  • Another object of the present invention is that of providing an electrical switch structure which is of significantly reduced size and which, moreover, is able to offer the widest guarantees of reliability and safety in use.
  • a further object of the present invention is that of providing an electrical switch structure whicb is easily obtainable starting from elements and materials which are commonly commercially available and which, moreover, has a very restricted cost.
  • a switch structure for motor vehicle electrical window winders charactersed by the fact that it comprises a box-like body closed at the top by a frame which defines seatings for housing a plurality of push-buttons contacting respective resilient electrically conductive blade supported at one end by a fixed contact on a printed circuit connected to a motor, and at the other end movable between a negative fixed contact and a positive fixed contact.
  • the switch structure particularly designed for motor vehicle electrical window winders which is generally indicated with the reference numeral 1, comprises a box-like body 2 which is closed at the top by a small frame 3 snap-engaged or press fitted thereto, which defines the seatings 4 for housing a plurality of push-buttons indicated 5.
  • the push-buttons 5 advantageously have illuminated ideograms on their visible surfaces, which are applied to a plate 6 fitted thereto and which are made of polycarbonate or by means of co-moulding.
  • the rubber seal 7 has a central bellows portion 9 which is interposed between an edge 10 which is gripped between the box-like body 2 and the frame 3, and an annular enlargement 11 which is housed in a groove 12 defined on the push-button 5.
  • the key 5 has in its lower part a tail 15 which acts by contact on a movable resilient blade 16 substantially folded into a U-shape or open loop which, at one end, is supported by a rigid printed circuit 17 and connected to a fixed contact 18 connected to a motor.
  • the resilient movable blade 16 has a terminal contact 19 which is movable between a fixed positive contact 20 and a fixed negative contact 21 for the various electrical connection requirements.
  • a spring 30 which acts between the printed circuit 17 and the push-button 5 in the region of the tail 15 to resiliently urge the push-button itself upwardly.
  • an electromagnet which is housed within the box-like body 1.
