Definitions

  • the invention relates to a switch contact arrangement consisting of two strip-shaped contacts which are relatively movable in their longitudinal direction with respect to one another and act upon one another, one of which is essentially rigid and the other is spring-loaded in the contact-making direction, the rigid contact having at least one longitudinal slot and one projecting beyond the contact plane has inclined run-up and drainage surfaces provided insulating web, which is in the open position opposite the resilient contact.
  • switch contact arrangements are known, for example from US-A-34 99 126.
  • the object of the present invention is to provide an improved switch contact arrangement in which, starting from a single “neutral” construction, a normally closed contact arrangement or a normally open contact arrangement can be implemented inexpensively with very little work, and in addition there is also the advantage of a longer service life and a lower risk of contamination is achievable.
  • a switch contact arrangement of the known type in that the insulating web is an integral part of a contact holder supporting the rigid contact on its rear side, the longitudinal slot being completely filled with an insulating material mass, which, however, in the switch-on area Contact areas not towered over.
  • the entire area of the longitudinal slot can be provided with an insulating material web projecting beyond the contact plane, which can then be worked off in the front area or in the rear area of the switching path. to create either a work or a break contact.
  • an insulating material web projecting beyond the contact plane, which can then be worked off in the front area or in the rear area of the switching path. to create either a work or a break contact.
  • the pressure switch shown in the drawings consists of a cup-shaped switch housing 1 of rectangular cross section, which is closed on the underside by a housing base 2.
  • the knife-shaped connections 4 provided for a corresponding socket protrude from the housing base 2 of the switch housing provided with guide pins 7. 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 2, bent in the area of the housing base 2, thereby promoting their safe storage.
  • the contacts 5 are given a further hold by plastic parts formed on the housing base 2 and projecting upwards and penetrating in the longitudinal slots 8 provided in the contacts 5 on the side facing the movable contacts 26. These longitudinal slots 8 have a length that corresponds approximately to the switch stroke.
  • an actuating piston 9 is inserted, which is firmly connected to a rectangular tube 10, which carries a push button 12 at the outer end and encloses a signal lamp 25.
  • the actuating piston 9 contains an inner cylindrical recess 40, in which the actual locking device of the pressure switch is housed in a completely encapsulated manner, with which the on and off position of the switch is fixed alternately when the push button 12 is actuated.
  • 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 slide guide path within the recess.
  • the movable contacts 26 are mounted on two opposite longitudinal sides of the actuating piston 9.
  • 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 severed at any point so that the switch can serve a plurality of independent circuits.
  • the “neutral” contact shown in FIGS. 3 and 4 consists of the metallic contact tongue 4, 5. Between the actual connection 4 and the actual contact 5 the tongue is molded into the housing base 2 of the switch housing or also inserted into a corresponding opening in a form-fitting manner.
  • the insulating material of the housing base 2 also extends in the form of an insulating material plate 50 along the back of the contact 5 in order to additionally support it.
  • the material of the housing base 2 and the insulating material plate 50 also penetrates the longitudinal slot 8 of the contact 5 and forms a continuous insulating material web 51 on its contacting side, which is chamfered at the front and rear ends to form a run-up or run-off surface.
  • the base of the insulating material web 51 can optionally also be somewhat wider than the width of the slot 8, so that there is a firm anchoring between the insulating material and contact 5.
  • the simplest means can be used to produce either an open contact according to FIG. 5 or a normally closed contact according to FIG Processed area of the switching path of the resilient contact 26, so that in the processing area the resilient contact 26 can slide only on the conductive metal of the contact 5.
  • this processing takes place below the contact surface of the contact 5, so that the resilient contact 26 does not have to act on any interfaces between metal and insulating material in the switched-on state.
  • Custom-made contacts are entirely possible according to the same principle according to the invention. If it is e.g. B. is a contact arrangement which has three switching positions in the longitudinal direction one behind the other for switching purposes, the longitudinal slot 8 can be extended by 50% compared to the embodiments shown in the drawings, the insulating web then the first and third thirds or even only fills the middle third of the longitudinal slot 8. This would result in switching functions "on-off-on” or "off-on-off”.
  • the rigid and resilient contacts have a very large width, it is also possible within the scope of the invention to provide a plurality of parallel longitudinal slots instead of a single central longitudinal slot 8 with corresponding insulating webs.
