Definitions

  • the invention relates to a switching element according to the preamble of patent claim 1.
  • the invention has for its object to provide a novel switching element which ensures good contact with a long service life of the switching element at low and medium loads.
  • Fig. 1 shows in a sectional view only one half of a switching element in a first switching position. A mirror image addition to the parts shown in FIG. 1 would result in a complete section through a switching element.
  • the switching element 10 comprises a housing 11 in which fixed contacts 12, 12 'are arranged in a stationary manner.
  • the switching element 10 further comprises a contact bridge support 13 slidably mounted in the housing 11, the contact bridges 14, 14 of which, depending on the position of the contact bridge support 13, galvanically connect two fixed contacts 12 or 12 'or interrupt a conductive connection between the fixed contacts 12 or 12'.
  • two fixed contacts 12 and 12 'are provided in pairs opposite one another in the housing 11.
  • one contact system is designed as a break contact or a make contact. It goes without saying that the invention can also be used for switching elements which either contain only break contacts or only make contacts or any combination of these functions in large numbers.
  • the cooperating end pieces of the fixed contacts 12, 12 'and the contact bridges 14, 14' are arranged obliquely with respect to the axis of movement of the contact bridge carrier 13.
  • the end pieces of the fixed contacts 12, 12 'and the end pieces of the contact bridges 14, 14' preferably lie in mutually parallel planes, although it should be noted that the contact bridges 14, 14 'are expediently resilient and in particular in the course of contacting them can first swivel the predetermined level reversibly.
  • the tilt of the cooperating end pieces of the fixed contacts 12, 12 'and the contact bridges 14, 14' leads to a particularly reliable contact even with only a low current load on the contacts, since the contact bridges 14, 14 'on the inclined contact surfaces 120 (FIG. 3) slide along the fixed contacts 12, 12 'and thereby pierce any existing oxide skins.
  • the fixed contacts 12 'and the contact bridge 14' have the function of an opener, while the fixed contacts 12 and the contact bridge 14 have the function of a closer.
  • the end piece of the contact bridge carrier 14 first touches the opposite contact surface of the respective fixed contact 12 and then slides along the inclined contact surface, as a result of which the previously described effect of penetration of the oxide skin occurs.
  • the resilient contact bridge 14 expediently yields somewhat.
  • the inclined position of the contact surfaces also results in particularly reliable contacting, actuation of the contact bridge support 13 in addition to the force component present in the actuation direction and also a force component in the lateral direction being effective.
  • the switching element is designed such that it can be easily attached in a plurality next to one another.
  • spring elements 110 are provided which, after the switching element has been plugged in, engage in fastening means (not shown).
  • FIG. 2 shows the second switching state of the switching element, mirror-symmetrical to FIG. 1, which is achieved by actuating the contact bridge carrier 13 in the direction of the arrow 200.
  • this switching state the galvanic connection between the fixed contacts 12 is interrupted, while the contact bridge 14'- establishes a conductive connection via the fixed contacts 12 '.
  • the contact surface 120 of the fixed contacts 12, 12 ' is made of a highly conductive material, e.g. B. fine silver, which is connected by plating to the fixed contact 12, 12 '. This is shown schematically in FIG. 3.
  • the contact surfaces 120 are expediently provided with an embossment 120 ′.
  • This embossing 120 ' is shown schematically in FIG. 4, which shows a view from the viewing direction X of the contact surface 120 of FIG. 3.
  • the prefix 120 ' preferably has a cutting-like profile with a triangular cross-section. This is illustrated schematically by FIG. 5, which is a sectional view along line 5 - 5 of FIG. 4.
  • the roughness depth of the embossment 120 ′ can be in the range from approximately 0.01 to 1 mm, but values in the range from approximately 0.05 to 0.2 mm are preferably selected.
  • the switching element is excellently suited for switching applications in the area of low current loads in the order of a few milliamperes and below that to medium loads in the order of a few 10 amperes.
  • the described shape and arrangement of the contact elements enable the problems caused by oxide formation to be mastered, in particular when the current load is low.
  • a long service life and reliability, especially with a higher current load, is mainly achieved by making it possible to choose the contact areas of the contact elements corresponding to the current load without impairing the function at low loads.
  • the contact surfaces can also be coated with precious metals, in particular gold.
