Definitions

  • the invention relates to an electrical switch, in particular a rocker switch according to the preamble of claim 1.
  • rocker switches consist of a switch housing with an upper operating rocker, as is known, for example, from DE 36 15 059 A1 by the applicant.
  • the actuating rocker has a downward, rod-shaped switching pin which, when the rocker is actuated, is connected directly or indirectly to a contact bridge or contact spring arranged transversely in the switch housing and presses it down to establish an electrical connection between two connecting lugs.
  • the central bearing of the contact bridge itself can be designed as an electrical connecting element to a connecting lug (DE 38 13 350 A1).
  • the electrical switch can also have a rocker arm with the same effect as the actuating element, as is shown, for example, in GB 1 094 822.
  • Such electrical switches can be bistable or monostable.
  • a bistable switch remains in two stable positions.
  • a monostable switch always returns to its starting position.
  • a bistable position is achieved, for example, by a dead center of a prestressed spring element being exceeded, as is shown, for example, in DE 36 15 059 A1.
  • a corresponding spring element is arranged in such a way that it cannot exceed a corresponding dead point.
  • the invention has for its object to provide a monostable electrical switch with a rocker or tiltable actuator, which provides a simple way to achieve the reset effect.
  • the electrical switch according to the invention with the characterizing features of claim 1 has the advantage that a monostable rocker switch or toggle switch is created, which is designed to be damped in a controlled manner in its tilting movement and whose reset mechanism is achieved by the simplest means.
  • an elastic, ie rubber-like or rubber-like element is provided according to the invention, which compresses when the actuating member is actuated, ie deforms elastically and after relieving the actuator exerts a force in the sense of a provision on it.
  • the elastic element is supported at a suitable point on the actuator and is pressed against the housing wall of the switch housing.
  • the elastic element is supported as a kind of rubber buffer between the switching pin of the actuating element and the switch housing wall.
  • the pot-shaped actuating rocker can have a correspondingly molded rubber element in its interior between the switching pin or a corresponding wall section and its outer wall.
  • the lower L-shaped leg is supported on the side of the switch housing.
  • the elastic element can also be arranged as a rubber-like buffer in the switch housing itself or in its base, a leg which projects laterally in the upper region being supported against the actuating member.
  • Decisive for the shape and the arrangement of the elastic element is its arrangement as a kind of rubber buffer between the actuator and the switch housing.
  • the two electrical switches 1, 2 shown in corresponding views in FIGS. 1 to 4 consist of a switch housing 3 with a rectangular cross section, which is cup-shaped and has a bottom plate 4 in its lower region (see FIG. 3) into which the electrical Flat connector contacts 5, 6 are used.
  • the two flat plug contacts 5, 6 are electrically connected via an electrically conductive contact bridge 7, as is shown, for example, in DE 38 13 350 A1.
  • the flat plug contact 5 is electrically connected to the central cutting edge bearing 28 for the contact bridge 7 via a web 29.
  • the contact bridge 7 is actuated via an actuating element 8, which in the exemplary embodiments is designed as an actuating rocker 8.
  • the operating rocker closes the pot-shaped switch housing, which is open at the top, in its upper, open area and is mounted in corresponding recesses 10 in the switch housing 3 via two lateral bearing pins 9.
  • the operating rocker 8 has a switching pin 11 projecting downward into the switch housing, the lower tip 30 of which is connected to the contact bridge 7 Switching element interacts (see DE 38 13 350 A1). This switching process is state of the art. Reference is made to the corresponding references.
  • an elastic element 12, 13 is provided according to the invention, which is clamped between the actuating rocker 8 and the switch housing 3.
  • this elastic element 12 is L-shaped, with a vertical first leg 14 inserted into the pot-shaped rocker housing, which is located between the side wall 15 of the cup-shaped rocker 8, which is open at the bottom, and the switching pin 11 the actuating rocker 8 supports.
  • the elastic element 12 has a second horizontal leg 16, the side surface 17 of which is supported on the lateral inner wall 18 of the switch housing 3.
  • the actuating rocker can also have an additional boundary wall 19 on which the vertical leg 14 of the elastic element 12 is supported. This wall 19 is only indicated by dashed lines.
  • the deformation of the elastic element 12 should essentially take place in the lower, horizontal leg 16.
  • the vertical leg 14 of the elastic element 12 is also laterally bordered by a boundary wall 20, 21, so that the actuating rocker 8 is designed as a pot-shaped housing which is closed at the top and at the side and is open at the bottom.
  • the alternative switch arrangement of the invention according to FIGS. 3, 4 is in principle of the same design as the switch arrangement according to FIGS. 1 and 2 with regard to the switching mechanism with regard to the actuating element 8, contact bridge 7 and flat plug contacts 5.
  • the switch housing 3 largely corresponds to the switch housing according to FIGS 2. The same parts are therefore provided with the same reference numerals.
  • the first vertical leg 22 is not arranged laterally in the housing of the actuating rocker 8 as in the embodiment of FIGS. 1, 2, but in the switch housing 3 itself.
  • a downwardly directed cup-shaped recess 23 is provided on the inner wall 18 of the switch housing 3, into which the vertical leg 22 of the elastic element 13 is inserted in order to fix it.
  • the inner wall of this receiving pocket is designated 24.
  • the elastic element 13 has a horizontal leg 25, which serves as a deformation element for the return effect of the actuating rocker 8.
  • the actuating rocker 8 can have an additional support wall 26 on which the inwardly directed side surface 27 of the horizontal leg 25 is supported.
  • the support wall 26 runs largely parallel to the side edge of the switching pin and enables a shortened design of the leg 25.
  • the elastic element 12, 13 can accordingly with its holding part, i.e. H. its essentially vertical leg can be arranged both within the operating rocker (Fig. 1, 2) or within the switch housing 3 (Fig. 3, 4).
  • the decisive factor is the elastic deformation of the elastic element 12, 13 in particular in its horizontal leg 16, 25, which brings about a return effect of the actuating rocker 8.
  • the elastic element can also be arranged in a separate base 4, which can optionally be inserted into the switch housing 3 from below.
  • the actuating element itself can also be designed as a tiltable actuating switch, as is shown, for example, in GB 1 094 822 for actuating the contact bridge.
  • the elastic element that is supported between the actuator and the switch housing is decisive as the restoring element.
  • the elastic element can be made of rubber or rubber-like material (elastomer) and, if necessary, vulcanized into corresponding parts of the electrical switch.
