Definitions

  • the invention relates to a illuminated pushbutton according to the preamble of claim 1.
  • An explosion-proof illuminated switch and illuminated pushbutton has become known from DE-A 34 06 295.
  • This illuminated pushbutton has a central guide part in which an actuating pin is guided while maintaining a gap that is resistant to ignition.
  • a switching element and light-emitting diodes together with a connecting line are cast into the housing which holds the light switch or light button.
  • An actuation button is placed on the actuation pin at the front.
  • This known illuminated pushbutton or illuminated switch is a device which can be manufactured by itself and which can be installed directly in a control panel housing and which, because of its size alone, is only designed for relatively low voltages.
  • the object of the invention is to provide a illuminated pushbutton with which the disadvantages of the known illuminated pushbuttons are avoided.
  • a illuminated pushbutton of the type mentioned is known from DE-A 33 33 135.
  • This illuminated pushbutton is composed essentially of two components that can be separated from one another, namely a housing head with a light unit and a pressure body and a surrounding housing, in which there is a mains supply device and a pressure-tightly encapsulated switching chamber space. It is essential for the known illuminated pushbutton that the so-called device head can be installed and removed or replaced at any time in a potentially explosive atmosphere without special tools. But this makes the design of the known illuminated pushbutton quite complicated.
  • the object of the invention is to provide a illuminated pushbutton of the type mentioned, which is easier to manufacture and easier to use.
  • the illuminated pushbutton can also be called a short illuminated pushbutton.
  • the illuminated pushbutton can have two pressure-tight switching chamber spaces according to claim 2.
  • the entire unit can be used in accordance with the characterizing part of claim 3 in an outer housing with increased security, wherein according to claim 4, the opening of the outer housing, from which the probe element protrudes, can be used to guide the probe element.
  • the illuminated pushbutton forms a unitary device in which special measures for connecting two components as in the device known from DE-A 33 33 135 are not possible.
  • an explosion-proof illuminated pushbutton 13 is used, which has a surrounding housing 14, which has three adjacent rooms 15, 16 and 17, which are separated by partitions 18 and 19 are separated from each other.
  • a transformer 20, which serves to supply power to a lamp unit 21, is accommodated in the middle space, which, as can be seen from FIG. 2, is approximately rectangular.
  • the two rooms 15 and 17, which are designed as pressure-resistant switching chamber rooms there is a fastening surface, on each of which there is a base 22 or 23, on which contact tabs 24 and 25 are attached, which carry fixed contact pieces 26 and 27, which with movable contact pieces 28 and 29 cooperate, which are attached to a contact bridge 30.
  • the contact bridge 30 is also connected to a switching plunger 31 or 32.
  • the contact lugs 24 and 25 are led out through the housing 14 and end in clamping lugs 33 and 34, to which connecting terminals 35 and 36 are attached.
  • niches 37 and 38 are formed in the region of the connecting terminals 35 and 36, which are delimited on both sides and inwards by walls 39, 40 and 41, as a result of which the air and creepage distances to neighboring ones Devices or to neighboring terminals 42 or 43 are enlarged.
  • the transformer 20 is connected (not shown here) to terminals 42 and 43, wherein these terminals 42 and 43 also sit in recesses 44 and 45 delimited by walls.
  • the walls for the niches 44 and 45 are on one side the partition 41; a wall 46 on the inside and a wall 47 running parallel to the wall 41 on the other side.
  • the terminals 48 and 49 belonging to the contact pieces of the switching chamber space 17 on the right are accommodated in the same way as the terminals 35 and 36 in niches 50 and 51, which correspond to the niches 37 and 38.
  • the walls in the area of the pressure-resistant rooms 15 and 17 and in the area of the middle room 16 have a circumferential recess 52, on which a cover 53 is placed, which is poured upwards by means of a casting resin compound 54.
  • a cover 53 In the cover 53 there are openings 55 and 56, respectively, through which switching plungers 31 and 32 are passed in a pressure-resistant manner; there is an air gap of a certain gap width and a certain gap length.
  • In the cover 52 there is a further opening 57 through which a lamp housing 59 extends, in which the lamps 21 are located.
  • the lamp housing 59 has a flange-like collar 58 which grips behind the cover 52 and thus secures the lamp housing 59.
  • the luminaire housing 59 is surrounded by a pushbutton element 60 which is covered at the top by a cover 61 which projects above the pushbutton element 60.
  • the sensing element 60 is adapted to the lamp housing 59 and engages around it.
  • the sensing element 60 has two projections 62 and 63 on both sides, which overlap the switching plunger 31 and 32, such that the switching plunger 31 and 32 can be actuated by means of the sensing element 60.
  • a passage 70 through which a sleeve 71 is inserted, which projects beyond the inside surface of the upper housing part and which is clamped or clamped to the housing by means of a nut 72 is screwed tight.
  • the sleeve 71 delimits a cylinder interior 73 and has at the inner end of the cylinder interior inwardly facing projections 74 and 75, which cover the outside diameter of the cover 61 inwards, so that a compression spring 76 and 77 is arranged between the cover 61 and the lugs 74 and 75 can be.
