Definitions

  • the present invention relates to a quick make-and-break switch or snap switch for controlling an electric motor for motor vehicles, suitable for driving directly the motor (power switch), always maintaining a feel of operation that is very similar to the one that is present on signal switches where snap action is obtained by means of silicone bubbles.
  • a water-tight switch is provided by using the same element (silicone pad) that is used for generating said feel of operation.
  • the above phenomenon can occur only on the normally open (NO) contact and not on the normally closed (NC) contact. In fact, it is only on the NO contact that by operating the switch the electrical load is interrupted, whereas on the NC contact only the passage of current occurs, and interruption is performed by another switch.
  • the metal lamina has a particular shape and mode of operation in so far as for the major part of its length it is substantially rigid, having two lateral turned-under edges that form a cross section substantially shaped like a U turned upside down, and this as regards the end 8 subject to the action of the actuator and the central part to which the fulcrum is connected.
  • the second end 9 that comes to occupy a position underneath the silicone bubble continues to be rigid up to a point underneath the bubble and is provided with a central slit with bent-down stiffening edges 9b, which is designed to centre it on the bubble 10.
  • the lamina terminates with the end part 9a formed by a flexible arched reed connected to the end 9 and carrying said electrical contact 11.
  • a normally closed (NC) faston connector 14 and a normally open (NO) faston connector 16 are in turn electrically connected by force fit or soldering to said printed or sheared circuit 19, which in turn carries the electrical connection to faston connectors 20 contained in the base 2b, which have the purpose of providing a connection to the wiring through which the electric motor of the power window is directly driven.
  • the plot of the force versus the displacement of the present actuator is mainly defined by the characteristic curve of the silicone bubble, which, notoriously, has a first stretch of travel in which the force increases and a second stretch in which it decreases, with a profile that is very close to a sinusoid.
  • the various metal components create a switch, in which the fulcrum 8 and the lamina 6 perform the connection with the "common" contact to be switched, and the NC faston connector 14 and the NO faston connector 16 alternately become the outputs.
  • the entire switch is then closed and sealed by the base 2b that carries all the components referred to above.
  • a second solution useful for rendering the system more reactive and faster has been to make the actuator 4 of elastic material, which enables manual actuation of the system to be rendered less controllable, in so far as the central section in the forward phase is compressed and at the moment of snap-action of the bubble 10 restores part of the energy, impressing on the lamina 6 an additional acceleration, whereas in the return phase it absorbs part of the acceleration impressed by the bubble rendering slow return of the lamina 6 impossible in the case where the user were to attempt to obtain slow return thereof.
  • an elastic intermediate element (silicone pad) 5 made of transparent material it will be possible to obtain lighting-up the outer surface of the button 1.
