Description

^{3 4}

A coupling element mounted on an actuating element in the center of the pivoting movement, which generates the jumping movement, is not released by a coupling element at right angles to the movement before switching over the contact, since the metal of the contact rivets knows that the actuating element is welded against each other Has elasticity and extensibility, engages the axis pivotably. _{s sn gmß sein ki4nr1] that in1 the} center of the swivel leg in many cases of application it is very desirable that no separation and loosening takes place,
The task of the present invention is to evaluate or close a sighting movement of the contact set of the type mentioned at the beginning in the direction of the contact plane, a contact set with a high level, so that impurities, Oxide layers 10 can be stripped off by a lateral displacement of the congestion and deposits due to coarse or fine clocks guaranteed contact load walleiiing of the contact material to create availability and service life, which is simpler and thus, with stronger currents, contact welding and space-saving structure than the known ßuiu'en necessarily separated by shear spring contact switch.

will. In relay contact spring sets this problem has been solved according to the invention so far by the fact that the contact spring, which forms the switching spring and the actuating HcIk contact half, has a common pivot axis or Einspanngeti.M the resting contact half in its member - exhibit. A particular advantage of a spring contact set according to the invention, which is carried on a little further, is that it can be built up very small after the two contact rivets have already become very small, which is often the case. the static contact skin is also of decisive importance for applications. dei: ■■! is arranged so that during the continuation of the spring contact set according to the invention, this contact half can therefore be resiliently made very small because the swivel contact can be calibrated. Since the clamping points of the Fe- .., ehse not laterally outside the contact set of the _; door the stationary contact half and the moving 35 is provided. It is also advantageous that the switching spring according to the invention is spaced apart from one another also as a changeover contact we ^: .n. lead with this additional Sc'iahbewe- can be formed, in which in both Schaltgui ■ the contact rivets a visual movement on positions the same switching behavior and the same ... Kier. This increase in the switching travel switching capacity is achieved. This advantageous characteristic and the arrangement of the stationary contact shaft results from the possibility of a completely ten on a spring and its deflection are in a much symmetrical structure. Finally, let’s benefit: filling undesirable. If, however, the additional, that despite the small structure, a high switching capacity, the switching travel is smaller and the deflection is achieved with a long service life, because the switching of the resting contact spring is smaller, then the behavior is reduced due to the shifting movement of the conduction and also very strong, and these sliding paths are then not bought by a large construction volume so small that contact welds are no longer necessary. It remains with the contact security according to the invention to be separated. The less the sliding arrangement has the advantage of the spring contacts, namely away, the less effective the self-instantaneous switching with almost the same cleaning of the contacts becomes. The two sets of contacts mentioned above, even with creeping actuation, have in common that, despite their small size, the
moving contact essentially perpendicular to the Da; The coupling element can be made from an electrically conductive contact surface of the stationary contact as well as from an electrically nonconductive one or impinges perpendicularly on the latter, without a material being produced. If it consists of a significant movement component transversely to this in front of 45 freshly conductive material, then lifting can occur via this, since the switching spring carrying the movable coupling element leads a second current path for the contact in the direction of its clock. The contact set can be mono as a clamping point or its pivot axis is rigid. also be made bistable.
In one embodiment of the invention, another known arrangement is achieved (German 5r> axial suspension of the switching spring by a bend Auslegeschrift 1214 2%), in which the switching spring or cranking of the switching spring is formed, the example part of a frame part clamped on one side is, wise krersegment-shaped, in particular C-shaped which is clamped on one end face and of its or U-shaped, or another opposite end face can have the switching spring in a suitable form. The coupling element can extend the space delimited by the frame. 55 by the known U-shaped, in the manner of a The free end of the switching spring is formed by a C-spring toggle lever acting spring or by a star with a one-piece with the frame, the res portion can be formed.
Switching spring connected to the leaf spring extending in the opposite direction. The end opposite the clamping point being clamped in like the switching spring and, in particular, the frame from which the switching spring extends over the contacts in the case of relay contact sets, serves as a starting point for the actuating force. When rivets extend up. In this arrangement, the actuating element can be a certain movement of the movable contact rivet pivotably mounted on the opposite side on the stationary Kon- or be clamped before switching over before releasing the contact on one of the clamping points of the switch. The use of the anti-friction rivet is achieved, and as a result, the ^f >& order is not limited to relay spring sets, releases. The disadvantage here, however, is that only a pivoting movement and not a viewing movement can be used for all other jump switches, the contact rivets are carried out on each other, so that in embodiments of the invention, the
