Definitions

  • the present invention relates to an electrical switch with vertical pushbutton of a simple embodiment and yet of great safety, this switch being able to be easily fixed on control panels of various machines and being able to simultaneously control one or two electrical circuits.
  • an electric push switch constituted by a main hollow body in which is slidable a push button one of whose lower parts supports two lugs maintaining pallets mobile carrying studs cooperating with studs integral with a bracket fixed to the bottom of the main body.
  • the tab laterally carries a hollow and heart-shaped cam in which a lug can circulate constituting the upper part of a locking element.
  • a spring centered on at least one finger secured to the underside of the push button is supported on the pallet.
  • the switch of the invention allows successive switching on and off operations that are entirely gentle, since the friction forces are very low and the members constituting the electric switch are very reliable, whatever the orientation or position of the switch, i.e. even if the switch is in a substantially horizontal position.
  • 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 the switch.
  • the vertical push-button electric switch is constituted by a hollowed-out main body in which the push-button can slide from top to bottom and from bottom to top, the lower part of which supports two tabs holding the pallets carrying terminals mobiles cooperating with studs integral with brackets fixed to the bottom of the main body; in addition, the tab laterally carries a hollow cam, generally in the shape of a heart, in which a lug can circulate fixed to the upper part of a pendulum articulated on an axis placed at the center of gravity of the balance, this axis being integral with the inner wall of the body so as to allow the opening and closing of at least one electrical circuit by the switch, this switch being characterized in that the pallet carrying the mobile terminals is held on hooks with upper inclined edges integral legs of the push button by a spring centered on at least one finger secured to the underside of the push button.
  • 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 elongated.
  • the upper edge 2a of the box 2 ends in a frame 4 intended to come to rest on the outer surface of the control unit in which the switch is incorporated which is held there by elastic tabs 5, at the upper ends of which are provided ridged surfaces 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.
  • the latter carry hooks 9 intended to hold pallets 10 (see fig. 9) at the bottom of which mobile terminals are fixed 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 secured to 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 with 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 center of gravity resulting passes through the pivot axis 21.
  • a locking ball commonly used requires grease which hardens over time. It is also possible to use plastic locking washers which must be curved, which is all the more complicated as the curvature 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, (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, o (see fig. 4) thereby allowing the closing of the electrical circuits controlled by the switch by application of the mobile terminals 11 on the fixed pads 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 passing through 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, thus allowing the switch remote control.
  • 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.
  • the pin 22 takes position C (position engaged, circuit closed); if the pusher is pressed again, the stud 22 escapes towards position D; then, by releasing the pressure on the pusher, the pin 22 returns to position A (switch open, circuit open).
  • the pin 22 is brought from position A to position B and the assembly is pivoted to the left towards position E, then the pressure on the pusher is released, a device with momentary action, the stud 22 circulating from position E to position F and from position F to position E.
