Definitions

  • the invention relates to a command and signaling device with a hollow cylindrical housing, one movable in it arranged hollow cylindrical plunger, a return spring, which on the one hand on the housing and on the other hand on Plunger supports, one arranged in the interior of the plunger Light element, especially an incandescent lamp, and with at least a switching element facing the light element End portion of the housing is attached.
  • the housing such as a push button and indicator lights designed command and signaling devices consists of a metallic one in some applications Material, e.g. Die-cast zinc to provide advantages in terms of mechanical Robustness and the visual appearance too achieve. Due to the electrical conductivity of the metallic Housing must take measures to ensure the necessary electrical separation and air gaps seized become.
  • the switching elements can this on the interaction with a metallic Partner.
  • the switching elements are directly on the actuator, i.e. the pressure switch or the rotary switch etc. or via an additional intermediary, i.e. a mounting frame that can also be metallic, snapped on or screwed on. In this way, fold-like layers are formed on the housing dividing levels Overlaps, welding or other measures such as insulation and spacing layers necessary.
  • the invention has for its object a command and To improve the reporting device of the type mentioned above, that with simple means the necessary safety against contact is achieved.
  • the object is achieved in that in the end region of the Housing a plastic part is integrated and the rest Residual housing is essentially metallic.
  • the plastic part is designed in this way can be that simple, inexpensive switching elements can be used, if necessary, for existing ones Plastic actuators are available and / or the economy a parallel offer of metal and plastic actuators increase.
  • the new solution with the plastic part offers manufacturing, functional and economical Advantages and improves ease of installation of the components when installed in a control panel.
  • the plastic part is made of consists of two identical half-shells, in the contours for axial, radial and angular fixation on the metal Residual housing are introduced.
  • the half-shells are advantageously radially brought up to the housing and snapped.
  • the material elasticity is used and on the other hand the axial stress caused by the actuating and restoring forces of the switching elements from the resilient Contours decoupled. It can also be used for fastening of the actuator serving on the control panel, the so-called Holders that enclose interlocked half-shells and thus a loosening completely during operation exclude.
  • Another advantage is the simplification of the metal housing or in the technical and / or economical production contours and undercuts that cannot be produced in one piece especially inside, which offers additional options for optimal Design of a push button or push button developed become.
  • the illuminated pushbutton 1 according to FIG. 1 is essentially off a housing 2, a plunger 3, a return spring 4, one Actuation button 5, a sealing ring 6, a lamp holder 7 assembled with a light bulb 8 and switching elements 13.
  • the housing 2 is hollow and cylindrical has - as usual - a front ring 9 in the actuation area on. Within the housing 2 is the hollow cylindrical Ram 3 movably mounted.
  • the return spring 4 is based on the interior of the plunger 3 and the housing 2 directed contact surfaces 10, 11 of the plunger 3 and Housing 2 from.
  • the contact surfaces 10 are directed inwards Cantilever 12 of the plunger 3 as molded insulating parts formed and therefore not electrically conductive.
  • the lamp holder 7 with the lamp 8 is on the actuation area end area facing away from the lamp holder 7 provided, the bulb 8 centrally in the interior of the Ram 3 is arranged.
  • the light bulb is the use other light elements are also conceivable.
  • the required Clearance between the base of the bulb 8 and the housing 2 maximized in a simple manner, in which the edition the return spring 4 in the manner described above on the housing 2 is done in isolation. Thanks to the potential-free support the return spring 4 can reliably touch the housing 2 can be avoided.
  • the floating support of the Return spring 4 is here in the metallic housing 2 at its end region facing the lamp holder 7 Integrated multifunctional part 14 made of plastic as a mediator realized. This consists of two half shells, the radially brought up to the housing 2 and snapped (see FIG 4.5).
  • the two identical half shells are Contours for axial, radial and angular fixation on the metal residual housing, an axial and radial latch with the partner part as well as for the coupling of Switching elements 13, lamp and circuit board carriers or the like brought in.
  • the material elasticity the plastic half-shells and on the other hand the Axial stress through the actuation and restoring forces the switching elements 13 decoupled from the resilient contours.
  • the one used to attach the actuator to the panel Element, the so-called holder can be used together enclose latched half shells and thus loosen during exclude the company entirely.
