Definitions

  • the present invention relates to a push button with a probe element, which in a Housing cover is slidably arranged to actuate a button or a Contact, which are arranged fixed to the housing behind the housing panel, wherein with the push button an actuator against the resistance of a Housing supporting spring element on the button or the contact can be pressed.
  • Such a pushbutton is known from German laid-open specification DE 30 37 448 A1, the structure of the push button and its installation in the housing being complex and are cumbersome.
  • the object of the present invention is to eliminate this disadvantage.
  • this is the case with a push button according to the preamble of the patent claim 1 achieved in that the spring element in one piece with the feeler element and / or the actuator is molded.
  • the actuating element advantageously has a latching element for holding the Push button in the housing. This allows the push button to be installed in the housing first be held captive in this, before then the housing panel with the corresponding openings for the push button mounted on the housing becomes.
  • the probe element or in particular the actuator has a stop, through which the displacement of the push button is limited inside the housing.
  • the push button is advantageously under tension mounted in the housing or the front panel.
  • the spring element at least has a spring arm which extends essentially in one plane, meandering extends along the longitudinal axis of the actuating element.
  • the feather is then especially robust and inexpensive designed for bending or torsional loads, if the spring arm not only in one level, but in all three levels, if necessary similar a helix, extends along the connecting element.
  • the push buttons can be held in the housing with a small lateral distance to each other.
  • the push button is advantageously made in one piece using injection molding technology and from plastic.
  • the direction of removal is for the injection molding production of the push button perpendicular to Oriented longitudinal axis of the actuating element and the push button in this regard without undercut educated.
  • two simply designed tool halves can be used without slide or other aids by linearly moving apart Generate complete pushbutton ready for installation.
  • a housing 1 In or on a housing 1 is a housing 1 forming or covering sections Front panel 3 attached (not shown).
  • the housing 1 faces behind the front panel 3 a plate-shaped bracket section 5.
  • Behind this inside the housing 1 a circuit board 7 is arranged at a distance from the front panel 3.
  • On the circuit board 7 is a short-stroke key 9 fastened with the aid of a in the housing 1 or the front panel 3rd held push button 11 is actuated from plastic.
  • the front panel 3 has a circular aperture 13 and in a corresponding Extension has the holding section 5 of the housing 1 in the direction of the Printed circuit board 7 to tapered sleeve 15.
  • the one-piece push button 11 protrudes a push button head 17, on which a push button cap 19 is fastened, into the aperture 13 or out of this to the front.
  • An annular shoulder 21 of the cap 19 engages behind the front panel 3 and secures the push button 11 captively in the housing 1 when the Front panel 3 is attached to the housing 1.
  • the pushbutton rod 23 has a stop disk 25, which with a corresponding paragraph 26 of the housing 1 or the bracket portion 5 as a path limitation serves for the push button 11.
  • the Probe rod 23 formed two spring slots 27, which act as a damping element in the axial Load the push button 11 serve.
  • the spring slots 27 or the thereby formed Damping element in the key rod 23 is prevented in the case of less favorable Housing and push button tolerances when pressing the push button 11 on the short-stroke key 9 too much force is exerted on them.
  • a stylus bead 29 is formed on the stylus rod 23. This is the push button 11 captive in the sleeve 15 of the housing 1 by inserting it before the push button 11 with the attached cap 19 by mounting the front panel 3 finally is fixed in the housing 1.
  • this has a spring element 31.
  • This is formed by two spring arms 33, which are on either side of the push rod 23 essentially parallel to this from the probe head 17 up to the level of the stop disk 25 stretch and end there freely.
  • the spring arms 33 are meandering and are supported with their free end section on the mounting section 5 of the housing.
  • the pushbutton 11 is mounted under tension behind the front panel 3, whereby a defined fit of the push button 11 and a pleasant operating feeling are achieved.
  • the Spring arms 33 are formed in the area of the probe head 17 and stabilize them three-dimensional meandering extension of the pushbutton 11 when it is moved in the housing 1.
  • the push button 11 with all its functional elements is formed in one piece and in Injection molding technology manufactured.
  • the spring elements 33 or Spring slots 27 designed so that a production with the simplest tools without Slider is possible.
  • the push button 11 is in relation to a direction of removal (arrows in Fig. 2) perpendicular to the longitudinal axis of the push rod 23 formed without undercuts.
