Definitions

  • the present invention relates to a switch assembly for electric appliances, which has been particularly designed for motor vehicles.
  • Prior switches for the above mentioned applications usually comprise LED's provided for displaying an ideogram or mark indicating the function of the switch, but these prior switches do not usually include means for displaying the position or condition of the switch, that is if the switch is opened or closed.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a switch for motor vehicle electric appliances, which has a very reduced size and can be assembled in a motor vehicle compartment in a very quick and simple manner.
  • a main object of the present invention is to provide such a switch which allows to display, in addition to an usual ideogram or mark, also the condition of the switch, that is its open or closed condition.
  • Yet another object of the present invention is to provide such a switch, specifically designed for motor vehicles and the like, which is very reliable and safe in operation and which, moreover, can be easily made starting from easily available elements and materials and which, accordingly, is very competitive from a mere economic standpoint.
  • a switch for electric appliances specifically designed for motor vehicles, characterized in that said switch comprises a switch body, which can be removably housed in a seat and supports a rigid printed board, to which there are connected an ideogram LED and an actuated-function LED, with said body there being slidably engaged a push-button supporting at least a movable contact cooperating with fixed contacts connected to said printed board, with said push-button there being associated a key, bearing an ideogram, which can be displayed by the ideogram LED, and with a pilot light, which can be displayed by the actuated-function LED.
  • the switch for electric appliances which has been generally indicated at the reference number 1, comprises a body 2 which can be housed in a seat 3 as provided on a motor vehicle, the body 2 being advantageously provided with resilient tooth elements 4, engaging with the edge of the seats and allowing said body to be held in its desired position.
  • a rigid printed circuit board indicated at the reference number 5, to which there are coupled blade-like contacts 6, allowing to provide an easy wiring connection with outside electrical appliances of the motor vehicle.
  • an ideogram LED 10 which generally emits a green light and which is centrally arranged and coupled to said printed board, there being moreover provided an actuated-function LED 11 which has advantageously an amber colour and is arranged on a side.
  • a push-button which has a substantially square shape and is provided, on its perimeter, with engaging tooth elements 21 effective to limitate the displacement of said push-button and being movably engaged in slots 22 provided through the body 2.
  • the push-button is provided, on a side surface thereof, with a guide path 25 for a stop tab 26 or lug, allowing to obtain a stable position of said push- button in its actuated state; to thatend, the guide path further comprises a recess 27 which can be engaged by the lug 26.
  • the push-button 20 is provided with at least a movable contact 28 which is removably engaged with fixed contacts as provided on the body 2 and connected to the blade-like contacts 6.
  • a key 30 which has a circular configuration and is provided, on the inside surface thereof, with an ideogram insert 31 providing a translucid region 32 for displaying said ideogram, and being provided with pin elements 33 which can be snap engaged in seats or recesses 34 provided on the top of the push-button 20.
  • a cylinder element 35 housing the LED 11, and being closed at the top thereof by a pilot light 36 allowing to emit a light indication as the push-button is its actuated condition.
  • the disclosed construction which has a very reduced size, is moreover made starting from a small number of component elements since, in addition to the above mentioned elements, that is the body 2, push-button 20 and key 30, there is provided a push spring 40 operating between the bottom of the body 2 and the push-button 20, in order to provide a resilient biassing force during the movement from the actuated position to the disenergized position and vice-versa of the push-button.
