Definitions

  • the present invention relates to an electrical switch and a method for its manufacture.
  • Electric switches consist essentially of a box-shaped body with a base element and a cover situated above capable of delimiting a seat for housing two metal contacts from which the corresponding bare ends of the wire connected to the switch: said metal contacts being slaved to a press-button with lever rotating around a transverse pivot which is supported by corresponding seats provided in the basic element, so as to achieve closure , respectively the opening, of the two user-controlled contacts, with the rotation of the button.
  • the base, the cover and the button dedicated to the switches are obtained separately, by injection of artificial plastic material into corresponding molds and successively assembled.
  • the main purpose of the present invention is to drastically reduce the aforementioned drawbacks.
  • the advantages deriving from the present invention essentially consist in that the manufacture of switches is greatly simplified and shortened thanks to the elimination of a molding phase and the phase of assembling the button to the cover, this, apart from the fact that it reduces the manufacturing time equally another condition compared to traditional technologies, also allows to reduce the impact of labor on the production cycle, as well as the quantity of plastic material complexly distributed to molds, with a great reduction in cost; that an electric switch according to the invention, apart from being simple and economical to manufacture, is very reliable even after an extended period of use.
  • FIG. 1 shows a switch according to the invention, in exploded perspective view
  • Fig. 2A show the switch of FIG. 1 assembled
  • Fig. 2B shows the plan view of the switch of FIG. 2A
  • Fig. 2C shows the sectional view along XX of FIG. 2B
  • Fig. 2D represents the sectional view along YY of FIG. 2B
  • Fig. 2E shows the sectional view along ZZ of FIG. 2B
  • Fig. 3 shows the view in perspective of the switch cover of the previous figures, in the inverted position
  • Fig. 4 shows the vertical section view of the push button and the switch cover shown in the previous figures, in enlarged scale.
  • an electric switch according to the invention is formed by a box-shaped body with a basic element (1) and a corresponding cover (2) capable of delimiting a seat for the accommodation of two metal contacts (4,4 ') where at least one of the two is flexible and elastic and where the corresponding bare ends of the wire (F) of the electric line connected to the switch are linked, and by a push button with lever (3) which is provided with two coaxial elements and protruding transversely from the sides of the button capable of forming a male element of a cylindrical hinge (30) supported by corresponding seats (10) of the basic element (1) and is intended to control the closing, respect the opening, of said contacts (4) by means of a cam appendage (31) oriented towards the base element (1).
  • said button (3) and said cover (2) are united with one another, with no solution of continuity, in correspondence with at least point (K) by means of a short piece of equipment.
  • the button (3) and the cover (2) of the switch are united by means of two short pieces of molding material corresponding to each sides of the button (3).
  • the force exerted on said points (K) by means of the elements (30) and derived from the pressure exerted on the button (3) at the end of obtaining rotation determines the rupture of each connecting piece between the button (3) and the cover (2), thus allowing normal use of the switch.
  • this includes the phases of producing the cover (2), the button (3) and the base (1) of the switch. with injection of artificial plastic material into corresponding molds, and involves making the button (3) and the cover (2) in one piece, at the same time, in the same mold or imprint, that is to say united without a continuity solution corresponding to at least one point (K): said connection between the button (3) and the cover (2) being produced with the same plastic material used for molding the same.
