Definitions

  • the present invention relates to an emergency switch for industrial motor vehicles including movable contacts which can be snap-closed on fixed contacts.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing an emergency switch for industrial motor vehicles in which the movable contact elements are specifically adapted to snap close on the fixed contact elements.
  • a main object of the present invention is to provide such an emergency switch for industrial motor vehicle, in which the closure movement of the movable contact elements is substantially independent from the operation of the driving push-button.
  • Another object of the present invention is to provide such an emergency switch for industrial motor vehicles, the movable contact elements of which are specifically designed for supporting comparatively high electrical currents and voltages.
  • an improved emergency switch for industrial motor vehicles characterized in that said switch comprises resilient point elements mounted on a slider driven by two arms forming bottom lugs of a rocker lever which is driven to swing by a push-buttom, through a rod which can in turn swing about a pivot axis thereof as controlled by a fork spring, said point element operating on movable contact elements so as to cause said movable contact elements to be snap engaged on corresponding fixed contact elements.
  • the emergency switch for industrial motor vehicles which has been generally indicated at the reference number 1, comprises a box-like body 2, between the walls of which there is pivoted a rocker lever element 3 provided with bottom lugs 4 and a side lug 5 upwardly directed and bearing a fork spring 6.
  • a second box-like body 7 including an intermediate horizontal wall 8 and a side abutment 9, thereabove there are applied two fixed contact elements 10.
  • the latter are adapted to supply, through a lamp holder construction 11 removably affixed onto the first box-like body, a lamp or a LED 12.
  • three blade-contact elements 16 and a foil 17 can oscillate, which perimetrically support two pair of pads 18 preferably made of an alloy of Ag/Ni.
  • the bottom portion of the second box-like body is so constructed as to provide a seat for receiving and snap engaging a related wiring terminal block.
  • a slider 19 which comprises two series of resilient point elements 20 and which is alternately driven by the bottom lugs 4 of the mentioned rocking lever, which lugs engage in corresponding opposite side seats 21 formed in said slider.
  • a third box-like body 22 In the top portion of the box-like body 2 there is engaged a third box-like body 22, downwardly opened, which comprises an intermediate vertical lug which rotatably bears a rod 23.
  • the rod 23 is provided, at a pivot axis thereof, with at least a radial projection 24 which can engage in the top of said fork spring 6.
  • the third box-like body in particular, is upwardly biassed by cylindrical springs 25 and is so designed as to define a side compartment 26 which extends above the lamp or LED 12.
  • an optical prism 27 adapted to deflect the light beam on the top surface of said box-like body, which is suitably slanted.
