Definitions

  • the invention relates to a pressure switch with stationary switching contacts arranged in the bottom of the switch housing, an actuating piston provided with an external pushbutton and carrying the movable switching contacts, axially movably guided against a return spring in the switch housing, and a latching device which acts between the actuating piston and the switch housing and consists of a link guide and guide pin holds the actuating piston after a first actuation in a first switching position and releases it again in a subsequent actuation to return to the rest position.
  • the two first-mentioned publications relate to pressure switches with an eccentrically arranged latching device which easily jams.
  • the third-mentioned publication works with a slide guide arranged in the longitudinal plane of the switch, which, although essentially centering the actuating forces on the center of the switch, requires a pivoting lever as an additional transmission element, which also has to be moved out of the axial center of the switch.
  • the main disadvantage is that the locking device is exposed inside the switch housing, so that interference can also occur there when dirt enters the setting.
  • the object of the present invention is to provide an improved pressure switch of the type mentioned in the introduction, in which the actuating forces acting on the latching device act exactly axially and can be arranged completely encapsulated in the slotted guide and guide pin in a very compact design.
  • the actuating piston contains an inner cylindrical recess in which, with a small distance from one another, circular ring surfaces have radially directed teeth of different tooth heights, which together form a circumferential zigzag-shaped Form a slide guide, and that a pin which engages in the cylindrical recess and is arranged centrally in the switch housing carries a diametrically extending, rotatably but axially immovably mounted guide pin, the ends of which engage in the link guide track.
  • the pressure switch shown in the drawings consists of a prismatic switch housing 1 of essentially rectangular cross section.
  • the housing 1 is closed at the bottom by a housing base 2, so that the entire housing is given a cup-shaped shape.
  • a housing base 2 At two or four points of the housing resilient snap-in catches 3 are provided on the outside, which give the possibility of inserting the pressure switch into a corresponding dashboard wall without the need for any screw connections.
  • the knife-shaped connections 4 provided for a corresponding socket protrude. These connections 4 are formed in one piece with the fixed contacts 5 provided in the interior of the housing 1.
  • the (in the exemplary embodiment) eight contacts 5 are in the switch housing in groups of four on opposite housing walls.
  • the contacts 5 with the connections 4, as can be seen from a comparison of FIGS. 1 and 3, are bent at 6 in the region of the housing base 2, which promotes their safe storage.
  • the contacts 5 are given a further hold by upwardly projecting plastic parts which are arranged on the housing base 2 and penetrate the longitudinal slots 8 provided in the contacts 5 on the side facing the movable contacts. These slots 8 have a length that corresponds approximately to the switch stroke.
  • a guide pin 7 for the socket On the underside of the housing base 2 there is a guide pin 7 for the socket and possibly also a recess into which switching elements, such as resistors and the like, can be inserted.
  • the inner cross section of the switch housing 1 is rectangular with rounded corners.
  • an actuating piston 9 is inserted into the switch housing 1, which is firmly connected at 28 to a rectangular tube 10 which carries a pushbutton 12 at the outer end.
  • a snap-in connection 11 between the tube 10 and the pushbutton 12 which gives the possibility of exchanging the pushbutton 12 or removing it for changing the signal lamp 25.
  • the box-shaped walls of the actuating piston tube 10 are recessed on the side faces at 31, so that the tube 10 is guided together with the actuating piston 9 only in the rounded corner parts 30.
  • the actuating piston 9, as shown in FIG. 5, is formed in two parts.
  • the upper and lower parts 13 and 14 to be firmly connected during assembly delimit the inner cylindrical recess 40, in which the actual locking device of the pressure switch is accommodated in a completely encapsulated manner.
  • In the recess 40 protrudes through a central opening 20 of the lower actuating piston part 14 in the bottom 2 of the switch housing 1 bolt 21, which also serves as a guide for a helical compression spring 22, which is on the one hand on the housing base 2 and on the other hand on the bottom of the actuating piston part 14 all around supports the bolt 21.
  • the spring 22 is the actual return spring for the pressure switch.
  • the bolt 21 In the interior of the recess 40, the bolt 21 carries a diametrically extending guide pin 23 which is axially immovable but rotatably mounted at the end of the bolt 21.
  • This guide pin 23 cooperates with a guide track 19, which is generated as follows.
  • the toothed circular ring surface 15 shown in FIG. 6 is located on the inside of the lower part 14 of the actuating piston 9 facing the recess 40.
  • the inside of the upper part 13 of the actuating piston 9 carries a toothed circular ring surface 16.
  • the teeth of the lower circular ring surface 15 have pairs differently shaped teeth, whereby - as the development according to FIG. 8 shows - the tooth bases 17a lower lie as the tooth bases 17b.
  • the pressure switch is in the switched-off state when the guide pin 23 lies in the lower tooth base 17a. If the guide pin 23 is located in the higher tooth base 17b, the switch is in the switch-on position.
  • the upper and lower annular surfaces 15 and 16 have four toothed Kreisringsegme t e 4 1, 42, so that 23 times the turn-on and twice the switched-off position is reached at a complete revolution of the guide pin.
  • the toothing on the upper part 13 of the actuating piston is designed such that it carries teeth 43a and 43b, which are of different heights and differ, in accordance with the higher and lower tooth bases of the lower part 14 high tooth bases 17a and 17b on the lower part 14 are substantially opposite.
  • the movable switching contacts 6 are mounted on two opposite longitudinal sides of the actuating piston 9 and fastened there at 28.
  • the free ends of the movable contacts 6 carry at their free end grinding brackets 7 for acting on the fixed contacts 5 arranged in a coaxial orientation.
  • a conductive connection results between the depressed and also depressed pushbutton 12 firm and mobile contact.
  • the connecting webs optionally provided between the movable contacts 26 can ensure that two or more of the connections 4 are connected to one another or not.
  • these webs 29 can be severed at any point so that the switch can serve a plurality of independent circuits.
  • the upper part 13 of the actuating piston 9 carries the socket 24 for a signal lamp 25, with which the switching state of the pressure switch can also be signaled to the outside via the aforementioned contact arrangement.
  • the push button 12 is of course provided with a corresponding opening, a translucent central section or the like.
