  • a switch device with multiple channels used to control organs or devices which can be operated in different directions and / or different movements.
  • such device provides logical control directions by relation to the senses of the movements ordered.
  • This type of switch device is commonly used in as a multidirectional control for an electronic game but it can also be used for any other type of device requiring an order according to at least two separate directions or two separate movements.
  • a liftgate So in utility vehicles or trucks, there are organs maneuverable in several directions such as a liftgate.
  • a control box with a button for actuation of the said tailgate and a button for downhill actuation.
  • Such a case can possibly also include a command button for deployment tailgate, a folding tailgate control button and, possibly a button for the orientation of the platform tailgate.

  • These switch devices generally consist of a housing containing several switches arranged in a circle opposite the periphery an oscillating mounted part in the housing, a lever control tiltable in several directions from a position of stable rest and which, when tilted, cooperates with the oscillating part so as to activate one of the switches. Once the lever is released, it returns to its position of stable rest under the effect of elastic return means, deformed when the control lever is tilted.
  • Such switch devices have structures relatively complicated and, in particular, a number relatively high parts used.
  • this device allows a reduction in the number of parts required to make a device multi-way switch
  • the shape of the body the single order offered is complex, due to the presence of radial tabs and requires the use of a mold also complex in shape which increases the cost of production.

  • the tilt lever when the tilt lever is tilted command, it tends to cause the tilting of the part flared towards the inside of the case, so that a pressure capable of exerting pressure on a contact means and next to a contact means can then exercise a pressure on this means of contact.
  • the tilting of said flared part is allowed by the thin portion of the peripheral flange which deforms while the portion thicker outer device of the collar device is kept fixed in the housing.
  • the thin portion of the peripheral flange tends to recover its initial shape and returns the lever to its initial position, the pressure exerted by said pressure means provided at the end of the part flared ceasing so the switch is open.
  • the elastically deformable material used to make the control member when it has a thin, is therefore easily elastically deformable whereas from a certain thickness it presents a greater rigidity and therefore deforms less well.
  • the thinness of the thin portion of the peripheral flange which allows its elastic deformation while the outer portion of said flange does not undergo no deformation due to said thicker thickness and of its attachment to the housing.
  • the axial rod and the part flared have an elastically thick material deformable sufficient to exhibit high rigidity.

So, in a housing provided with such a switching device, the inclination of the control member towards the top of the housing can control the lift of the tailgate while tilting towards the bottom of the box activates the descent of the tailgate.
  • the tilt to the left of the box controls the tilt of the tailgate platform towards the top while tilting to the right of the housing the control unit triggers the tilting of the platform down.
