Definitions

  • the present invention relates to an attachment push button, in particular for electrical switches, which is guided and held in a cover plate and is actuated by hand against the force of an ejection spring, a front, fixed flange being provided to limit the actuation travel and a rear stop to limit the ejection travel are.
  • Attachment snap fasteners usually have a fixed front flange. They are inserted into the cover plate from the front and then secured against falling out by attaching a removable rear stop. The attachment push buttons are thus captively connected to the cover plate, which results in simple mounting of the cover plate on the separately installed electrical switching devices.
  • an attachment push button in which the rear stop consists of two parts that can be joined together with the push button, a rubber O-ring and a stop ring with an angular cross section.
  • the rear part of the push button itself is equipped with a semicircular circumferential groove.
  • the stop ring with the smaller inner diameter is pushed forward onto the front push button inserted into the cover plate; the rubber O-ring is then placed in the circumferential groove and the stop ring is pushed back down over the rubber O-ring.
  • the two additional parts secure each other; While the stop ring is held by the rubber O-ring on the attachment push button, the stop ring with its outer leg surrounding the rubber O-ring prevents the rubber O-ring from jumping out of the circumferential groove.
  • the present invention has for its object to provide a front push button that is attached as a compact unit to assembled push button boxes or control panels and without additional tools from the outside and automatically attached and can be removed from the outside with the simplest of tools without dismantling the cover plate.
  • the attachment push button can be inserted into the front of a tableau cover plate without tools and holds automatically without requiring access to the rear of the cover plate, and that it can be operated with the aid of a Strips of thin PVC film can also be removed from the cover plate without having to disassemble the cover plate itself. For this purpose, slide the film on the two sides of the bracket between the push button and the slide guide until the stop cams of the rear stop are well covered. To facilitate this procedure, the front push button can be pushed slightly inwards to a middle position. The resolution The push button can now be removed from the cover plate, and most advantageously if the push button and the film are gripped together with the fingers and pulled out of the cover plate. A strip of thin but firm paper can also provide services similar to a PVC film.
  • Another advantage is that subsequent changes to floor or function names can be carried out within seconds by replacing the correspondingly marked push buttons without any other dismantling work.
  • 1 denotes a cover plate which has a through hole 1.1 for the installation of a sliding guide and an attachment push button.
  • 2 is an attachment push button which has a front flange 2.1 and two transverse slots 2.2 and 2.3 arranged directly in front of the rear opening, as well as a front opening 2.4 for the light exit of the indicator lamp (not shown) and a glued-on label plate 4.
  • a U-shaped retaining leaf spring is designated by 3 with two legs 3.1 and 3.2 bent at right angles.
  • An approximately 12 mm wide strip of dismantling film 5 is indicated by dash-dotted lines.
  • the sliding guide which is inserted and fastened in the through hole 1.1 of the cover plate 1, is designated by 6.
  • a spring-loaded support7 of a switch (not shown) mounted on the rear holds the push button in the desired rest position.
  • 11 denotes a cover plate, which likewise has a through hole 11.1 for the installation of an attachment push button.
  • a slide guide 14 is engaged in the through hole 11.1.
  • the front button is labeled 12; it is pressed from transparent plastic and has a front flange 12.7 and a rear stop, consisting of two spring tongues 12.1, 12.2 with an inclined guide surface 12.3, 12.4 and a stop cam 12.5, 12.6.
  • An approximately 12 mm wide strip of dismantling film is indicated by dash-dotted lines and designated 15.
  • In the cavity of the push button there is an opaque but translucent one Insert 13 made of pressed plastic. This insert 13 can be unlabeled or provided with a marking which indicates the function or the associated floor designation of the push button.
  • a sprung support 17 of a switch, not shown, mounted on the rear also holds this push button in the desired rest position.
  • the header push button according to Figures 3 and 4 has the advantage over that of Figures 1 and 2 additional advantages: It can due to its design without any M assnah- men in the recess of the dormant in the cover plate slide are pressed and adheres also automatically by the stop cams of the Spring tongues on the rear flange of the slide guide.
  • this front push button is actuated, the movement is also limited by the abutment of the upper flange on the slide guide, and when the front push button is released, it also snaps back into the rest position under the action of the spring-loaded support of the switch mounted on the rear.
  • both movements are dampened by the damping effect of the materials of the front push button and the sliding guide for the rear and front strikes, so that practically no striking noises occur.
  • the front push button is removed again with the help of the PVC film in the same type described.
  • the invention is not limited to the illustrated embodiment.
  • the stop cam could also be, for example, a cylindrical pin which is pressed outwards by a compression spring and secured in the interior of the push button with a flange, which is slidably guided in the body of the push button.
  • a cylindrical pin which is pressed outwards by a compression spring and secured in the interior of the push button with a flange, which is slidably guided in the body of the push button.
  • a flange which is slidably guided in the body of the push button.
