Definitions

  • the invention relates to a pressure switch with stationary switching contacts arranged in the housing 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, which holds the actuating piston in a first switching position after a first actuation 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 switch designs according to GB-A-698 547 and FR-A-929 828 also make use of toothed circular ring surfaces and a rotatably mounted guide pin.
  • a disadvantage of these previously known arrangements is that the rotatable guide pin must also perform an axial movement in addition to its rotational movement during each switching operation. In this way, the risk of jamming is particularly great and faulty contact is more than likely, since the guide pin, which is movable in the axial and circumferential directions, itself forms a conductive bridge piece which has to bridge the fixed contacts arranged eccentrically to the switch axis.
  • 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 the slide guide, and that an engaging in the cylindrical recess, arranged centrally in the switch housing carries the diametrically extending, rotatably but axially non-displaceably mounted guide pin, the ends of which engage in the slide guide.
  • Embodiments of the invention are the subject of the dependent claims.
  • the pressure switch shown in the drawings consists of a prismatic switch housing 1 of essentially rectangular cross section.
  • the switch housing 1 is closed at the bottom by a housing base 2, so that the entire housing is given a cup-shaped shape.
  • 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 from the housing base 2 of the switch housing. These connections 4 are formed in one piece with the fixed contacts 5 provided in the interior of the switch 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 are, as can be seen from a comparison of FIGS. 1 and 3, bent in the area of the housing base 2, thereby promoting their safe storage.
  • a wide one Ren hold get the contacts 5 by arranged on the housing base 2 upwardly projecting plastic parts which penetrate in the contacts 5 provided longitudinal slots 8 on the side facing the movable contacts.
  • These longitudinal slots 8 have a length that corresponds approximately to the switch stroke. Characterized in that the longitudinal slots 8 penetrating plastic mass is processed in the upper or in the lower area or not co-molded, it can be achieved that the movable contacts to be described below establish a conductive connection either when the pressure switch is pressed or not pressed.
  • 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. can be inserted into the switching elements, such as resistors and the like.
  • 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 to a rectangular tube 10 which carries a push button 12 at the outer end.
  • a snap-in connection 11 between the rectangular 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 rectangular tube 10 are recessed on the side surfaces at the point 31, so that the rectangular tube 10 is guided together with the actuating piston 9 only in the rounded corner parts 30.
  • the actuating piston 9 is, as shown in FIG., 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 (lower part 14) in the housing base 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 underside of the Actuating piston part (lower part 14) is supported around the bolt 21.
  • the helical compression 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 On the inside of the lower part 14 of the actuating piston 9 facing the recess 40 is the toothed circular ring surface 15 shown in FIG. 15.
  • the inside of the upper part 13 of the actuating piston 9 bears a toothed circular ring surface 16 accordingly.
  • the teeth of the lower circular ring surface 15 have different pairs configured teeth, whereby - as the development according to FIG. 8 shows - the tooth bases 17a are lower than 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 circular ring surfaces 15 and 16 have four toothed circular ring segments 41, 42, so that when the guide pin 23 is rotated completely, the switch-on position and the switch-off position twice are reached.
  • 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 26 are mounted on two opposite longitudinal sides of the actuating piston 9 and fastened there at point 28.
  • the free ends of the movable contacts 26 carry, at their free end, grinding brackets 27 for acting on the fixed contacts 5 arranged in a coaxial orientation.
  • a conductive connection between the fixed results when the push button 12 is pressed or not pressed and moving 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 placed anywhere be cut 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.
