Definitions

  • the present invention relates to an electrical switch with vertical pushbutton of a simple embodiment and yet of great safety, this switch can be easily fixed on control panels of various machines and can simultaneously control one or two electrical circuits.
  • the present invention overcomes these drawbacks by creating an electrical switch with a vertical push button having a locking pendulum whose pivot axis passes through its center of gravity, thereby obtaining a perfect balance of this pendulum.
  • the constitution of such a switch makes it possible to obtain excellent contact because the mobile terminals come first to rest obliquely on the contact pads, then in parallel with a slight rolling movement so as to allow self-cleaning of the contact pads when closing or opening of the switch.
  • the electric switch consists of a hollowed-out main body in which a push button can slide from top to bottom and from bottom to top, the lower part of which supports two tabs holding the movable terminal-holder bars cooperating with studs fixed to brackets fixed in the bottom of the main body, in addition, the tab laterally carries a hollow, heart-shaped cam in which a lug can circulate fixed to the upper part of a balance articulated in a balanced manner on an axis integral with the interior wall of the body to allow the opening and closing of at least one electrical circuit by the switch.
  • the pallet carrying the mobile terminals is held on the hooks secured to the tabs of the push button by a spring centered on at least one finger secured to the underside of the push button.
  • Fig. 1 is a perspective view, partially exploded, of the vertical push-button electrical switch.
  • Fig. 2 is a cross section of the switch substantially along line II-II of FIG. 1.
  • Fig. 3 shows, in partial perspective, a modified element of the switch.
  • Fig. 4 is an elevation, on a larger scale, of an element of the switch.
  • Figs. 5 and 6 show the position of the mobile terminals in relation to the fixed studs.
  • Fig. 7 is an elevational view, on a larger scale, of another part of the switch.
  • Fig. 8 is a side elevational view, and on a very large scale, of a variant of the part of FIG. 7.
  • Fig. 9 shows, in plan, the support of the mobile terminals.
  • Figs. 10 and 11 show the first the open switch and the second the closed switch.
  • Fig. 12 is a schematic elevation showing a modification of an element of the switch.
  • Fig. 13 shows a slight variant embodiment of FIG. 7.
  • the main body 1 of the switch which is constituted by a substantially cubic box 2 extended, at its central lower part, by a receptacle 3 narrow and of elongated shape.
  • the upper edge 2a of the box 2 ends with a frame 4 intended to come to rest on the external surface of the control box in which is incorporated the switch which is held there by elastic tabs 5 at the upper ends of which surfaces are provided. ridged 5a.
  • This switch fixing device is also known per se.
  • the push button designated by 6, consists of a solid body extended downwards by tabs 7, 8. These der motos carry hooks 9 intended to hold pallets 10 (see fig. 9) to the lower part of which are fixed mobile terminals intended to cooperate with fixed studs 12 mounted on conductive brackets 13 passing through the bottom of the box 2 (see fig. 2).
  • the extra thickness 14, provided in the pallets 10, allows the centering of a spring 15 held by a finger 16 secured to the underside of the push button 6 (see fig. 2).
  • the spring 15 thus firmly holds the pallets 10 on the oblique hooks 9 which can be inclined inward (see fig. 1 and 2) or outward (see fig. 5 and 6).
  • a locking balance 20 is articulated on an axis 21 integral with one of the transverse sides of the box 2.
  • This locking balance 20 has two parts, one long 20a and the other short 20b, the part 20a being provided at its upper end of a lug 22 located below the pivot axis 21.
  • the two parts 20a and 20b of the locking balance 20 are calculated so that their resulting center of gravity passes through the pivot axis 21 These conditions make it possible to construct this locking pendulum in a simple manner in plastic or metallic material.
  • a locking ball commonly used requires grease which hardens over time.
  • Worm rings can also be used rusting in plastic which must be curved, which is all the more complicated as the curve disappears with the increase in temperature, especially when the switch is used on devices or machines requiring, for their operation, heat.
  • the lug 21 is intended to cooperate with a cam 23 having substantially the shape of a heart hollowed out in the tab 7 of the push button 6 so that by pushing the push button 6 in the direction of the arrow F 1 ( see fig. 4), the lug 22 which is located in the lower part of the hollow cam 23 (see fig. 10) follows a movement defined by the arrows F 10 (see fig. 4) thereby allowing the closing of the electrical circuits controlled by the switch by applying mobile terminals 11 to the fixed studs 12.
  • a spring 30 placed behind the balance 20 tends to push up the push button 6 while resting on the bottom of the receptacle 3 and against a vertical guide 31 secured to the tab 7. The result is thus easy return to the switch open position when the lug 22 has left the central part 23a of the heart-shaped cam 23.
  • the locking balance 120 is constituted by a bar crossing the bottom of the receptacle 3 so as to allow the control of this balance 120, from point 121, either by a linkage or by an electromagnet, thereby allowing the remote control of the switch.
  • the various parts constituting the switch are most often made of natural or synthetic plastic material, the dielectric nature of which no longer needs to be demonstrated and the resistance of which is extremely good. Only the brackets 13, the pallets 10, the terminals and studs 11, 12 as well as the springs are made of metal.
  • the heart-shaped cam 23 may have in its central zone 123 (see FIG. 4) a dish leading to an inclined part allowing automatic and remote-controlled operation of the switch.
  • the pendulum 220 can have a slight modification of its axis of rotation 223 which can be square. In any case, these modifications mean that the balance is perfectly balanced and can therefore constantly take up any position.
