Definitions

  • the invention relates to a push-button switch particularly suitable for controlling tool machines.
  • the invention aims to provide a push-button switch having at least two buttons or keys so that, when one button is pressed, a programme sequence is carried out where, for example in the case of an automatic turret machine, the work is clamped, the turning tool is brought into position and the work is turned to a given length and severed. When a further button is pressed another programme sequence takes place, for example at another part of the machine.
  • the invention also aims to construct the push-buttons and/or controls so that contact-making is effected in a small space, with low production costs and a shockproof construction and very safe operation, and also so that the push-buttons can easily be replaced using key-like tools and can be mounted so that the fastening positions are not visible.
  • Push-button switches comprising a plurality of juxtaposed switch keys, each of which moves a slide in the direction of actuation, which in turn operates a cross-slide transversely to the direction of actuation until the contacts mounted on the cross-slide make contact.
  • Such push-buttons are used, for example, in radio sets where, for example by pressing the ultra-short wave key, contacts are closed which switch over the aerial accordingly and effect the subsequent switching processes.
  • the invention aims to avoid these disadvantages and to permit many contacts to be actuated by one push-button or key but also to facilitate actuation of individual contacts in order to alter the programme.
  • a plurality of cams corresponding to a switching programme is mounted on the spring-loaded slide of the push-buttons or keys and engage contact slides carrying the programme contacts.
  • the slide which is integral with the push-button, no longer has many contacts mounted on it but serrations, cam profiles or the like are provided which, in turn, actuate many cross-slides in the form of contact slides.
  • These contact slides generally operate only one contact so that, by judicious spacing and construction of the serrations on the slide, only one contact slide can be actuated to operate the appropriate contacts.
  • contact slides prefferably be springloaded against their direction of movement and to possess recesses in accordance with the spacing of the push-buttons with projections bearing on the cams of the pushbutton slides.
  • the projections in the contact slide recesses prefferably be arranged adjacently or offset and to match the cams on, or recesses in, the push-button slides.
  • buttons or keys can be replaceable, it is desirable for the slides of the push-buttons to be provided near the push-buttons with projections which displace the contact slides far enough for the push-buttons to be removed with the slides.
  • the contact slides lock the push-buttons. If corresponding projections on the pushbuttons and/ or their slides engage recesses in the contact slides, the latter are displaced so that the push-buttons can be changed.
  • the projections arranged near the push-buttons permit the uppermost holder, which takes the form of a cover strip, to be moved far enough to enable the push-buttons to be exchanged.
  • this cover strip may equally well be fixed with screws to enable the buttons to be exchanged.
  • the cover strip is replaced by a specially constructed lock slide which serves to lock the individual push-buttons. It the lock slide is appropriately displaced, for example by means of a tool, the push buttons can be changed.
  • the push-buttons can be changed.
  • Such ease in changing the push-buttons is important since now dilferent push-buttons with different projections switching on a different programme can be inserted by linear displacement or rotation if the greatest possible variety of programme preselection and sequence is to be made use of.
  • the switch casing accommodating the push-buttons and slide springs prefferably have tapped holes to receive the mounting screws connecting the push-button casing to the switch casing.
  • the two casings can be joined by means of the lock slide by fixing the pushbutton casing without any push-buttons and slides on the switch casing and then inserting a tool to bring the lock slide into a position where the push-buttons with the slides and slide springs can be readily inserted.
  • the slides lock the switch housing through the lock slide. Unauthorised persons are therefore unable to change any parts, and the fastening has a pleasing appearance on the outside.
  • Various tools can be used to actuate the lock slide.
  • One possibility is for a slot aligned with the gap between the push-buttons to be provided in the switch and pushbutton casing for the insertion of a tool which moves the lock slide in one direction and the still blocking contact slide in the other direction.
  • the push-button casing carries the push-buttons
  • the slides may be rectangular, square or polygonal in section, and a desirable arrangement is for the push-buttons to operate square slides having carns or recesses on all their surfaces, so that the contact slides are displaced when the slides of the push-buttons and the puslrbuttons themselves are reciprocated and/ or turned.
  • buttons or keys may have rest or operating positions, the rest position being obtained by a turning and/or reciprocating movement.
  • FIG. 1 illustrates tle arrangement of two pushdreys with three contact slides
  • FIG. 2 is a plan view of a contact slide as shown in FIG. 1 without keys
  • FIG. 3 is similar to FIG. 2 but with the contact slide arranged for different contact actuation
  • FIG. 4 shows groups of contact slides with one key
  • FIG. 5 is a possible construction of recesses and projections inside the contact slide
  • FIGS. 6 to 9 are diiferent constructions corresponding to FIG. 5,
  • FIG. 10 illustrates the arrangement of a cover strip to enable keys to be exchanged
  • FIG. 11 illustrates the key and switch casing with one lock slide and contact slide
  • FIG. 12 shows a construction of the lock and contact slide
  • FIG. 13 shows a diiierent construction
  • FIG. 14 shows the construction of a slide for an operating position.
  • contact slides 2, 3, 4 are mounted on a base 1 and are urged by springs in the direction of the arrow 5.
  • the contact slides have apertures or recesses 6 in which the slides 7, 8 are reciprocated.
  • the slides 7, 8 are provided with push-buttons or keys 9, 10. If one or both of the push-buttons 9, 10 are pressed in the direction of the arrow 11, then the cams 12 mounted on the slides cause the contact slides to move in the direction of the arrow 13. However, only the contact slide 2, 3, 4 of which the recess 6 is touched by the cams 12 is moved.
  • the buttons 9, 10 are, of course, mounted in bearings 14.
  • a contact slide 2 is shown in plan, also mounted in bearings 14.
  • the recesses 6 are of rectangular section and, depending on which of the cams 12 of the slides 7, 8 touches a recess 6, the appropriate contact slide 2, 3, 4 is pushed in the direction of the arrow 13 against the action of the spring 15.
  • Contacts 16, mounted perpendicular to the direction of the arrow 13, are then operated by these contact slides and switch on any part of the machine (not shown).
  • FIG. 3 shows that projections 17 can be arranged on the contact slide 3 to move the contacts 16 parallel to the direction of the arrow 13.
  • FIG. 5 shows the relative arrangement of four such contact slides forming a group.
  • One has a projection 21, the next the projection 22, the third the projection 23 and the last the projection 24. If the slide '7 is moved by the button 9 in the direction of the arrow 11 in FIG. 4, then that contact slide of the group 18 whose appropriate projection 21 to 24 bears on the corresponding projection of the slide 7 will be moved.
  • the contact slides forming the group 18 are constructed as those in FIGS. 2 and 3 as regards springing and contact arrangement.
  • H6. 10 illustrates the possibility of exchanging buttons.
  • a laterally displaceable cover strip 25 with a recess 26 takes the form of a contact slide.
  • an enlarged projection 29, arranged below'the push-button in this example advances the cover strip a further distance 30 in the direction of the arrow 2%.
  • FIG. 11 shows the push-button casing I54.
  • This may be in the form of a cover, or it may be a strip connected to the switch casing 36 by fastening screws through the threaded holes 37 in the switch casing.
  • the push-button casing accommodates the push-buttons 38 and slide springs 39.
  • One of the push-buttons is shown in section, and the slide spring 39 is illustrated diagrammatically.
  • the slide is releasably or unreleasably connected to the push-button 33 and provided with projections 4-1 or cams for displacing the contact slide 42 which takes the form of a cross-slide.
  • Contact slides 42 are provided in accordance with the number of projections 41 and in turn actuate programme contacts (not shown).
  • the lock slide 43 is arranged above the contact slides 42.
  • the two slides 42 and 43 are supported by springs 44 which cause the contact or lock slides to be returned to their starting position when they have been moved.
  • the lock slide 43 has a bent-out lug 45 and the contact slide 42 a lug 46 bent in the opposite direction.
  • the gap 47 between the buttons and a slot 48 aligned with this gap, together with the switch and pushbutton casings are used for inserting a knife-shaped instrument 49. If this is inserted in the direction of the arrow 51) the legs 45, 46 are applied to the instrument 49.
  • the lock slide 43 is thereby moved in the direction of the arrow 51 and the contact slide 42 in the direction of the arrow 52.
  • the opening formed by the recesses 53 in the lock slide and 54 in the contact slide now permit the projection 41 to be released and the slide 40 is removed in the direction of the arrow 55.
  • the lock slide 43 it is of course also possible, forexample, for the lock slide 43 to be stationary and only the contact slide 42 to be moved. In the same way slots 48 may be arranged adjacent each push-button so that each push-button can be changed separately.
  • the lock and contact slides can have recesses 56, 57 with tapered sides 53, 59 (FIG. 13) which also cause a displace ment in opposite directions when a suitable instrument is inserted, thereby aligning the recesses which engage under the projections 41, and thus enabling the slide 40 with the push-buttons 38 to be changed.
  • the slides 40 may also have conical projections 60 (FIG. 14), these being dimensioned so that they cannot pass through the recess 54.
  • the contact slide 42 of FIG. 14 is moved in the direction of the arrow 62- while the spring 44 is stretchedonly so long as the pressure on the slide 40 in the direction of the arrow 61 is maintained.
  • Scanning contacts 63 which may for example be used as starting contacts in a programme control sequence, are thereby closed.
  • the invention can be used in all cases where a great variety of controls are required to be effected using a push-button or key unit.
