Definitions

  • the invention relates to an electrical switching device with a housing with at least three contact points each formed by a movable contact piece and at least one fixed contact piece, which are arranged separately from one another in mutually parallel switching paths of the housing, which movable contact pieces by an associated actuator movable about a pivot axis , for example switching rocker, can be acted upon, which actuator moves the associated movable contact piece from a first switching position into a second switching position.
  • Series switches are switches with at least two switching tracks arranged next to one another, in each of which separate contact points are arranged which can be actuated independently of one another.
  • Each switching track is assigned an actuating element, for example a rocker switch or a rocker arm, which enables independent switching actuation of the relevant contact point and thus of the relevant circuit. If different circuits are to be switched at the same time, this is possible by applying the relevant actuating elements simultaneously.
  • a synchronous switching by actuating a single actuating element is not possible. Instead, simple switch-offs are provided in such cases, in which a separation of the circuits is not provided, but which have a common phase connection, which by means of a contact point is switched to an output that may be double.
  • each switching track with contact points arranged therein is assigned an actuator which can be actuated independently of the adjacent actuator, that all actuators have a common pivot axis and that each actuator has switching cams for actuating at least one contact point.
  • each actuator arranged on an outside has an extension on its outward-facing side which extends with the pivot axis and which cooperates with a corresponding recess in the housing. Furthermore, an axially identical blind hole-like recess is provided on the side of the actuator opposite the molding, into which a thru-axle can be inserted.
  • the actuators arranged therebetween have a continuous recess through which the thru-axle extends, which serves to bridge the distance between the actuators located on the outside and thus to ensure that the actuators are held in their assigned position.
  • the thru-axle is held in a form-fitting manner in the blind hole-like recesses of the actuators arranged on the outside, the pivoting mobility of the actuators is ensured independently of one another.
  • the thru-axle can be locked in the blind hole-like recesses of the actuators arranged on the outside.
  • an annular projection or an annular groove can be provided on the thru axle or in the blind hole-like recess in the actuator, which cooperates with a compatible design on the respective counterpart, that is, for example, an annular bead formed on the thru axle engages in a corresponding annular groove the blind hole-like recess.
  • an actuator on its side facing away from the outside can have a molding bridging the adjacent switching path and penetrated by the plug-in axis, on which additional switching cams for actuating the contact point in the adjacent switching path are formed.
  • This design permits the optional use of uniform actuators in a switching device according to the invention if each switching path is to be designed to be switchable independently of one another.
  • a simple actuator and a so-called double actuator according to the previously described configuration can be used in one and the same switching device, which at the same time ensures the actuation of two adjacent switching tracks, by additionally forming a switching bridge on the actuator provided with switching cams with molded parts thereon Switch cams for actuating the contact point in the adjacent switching path.
  • each actuator can also be provided on one side surface with formations which correspond to compatible formings or recesses on an adjacent actuator, that is to say are in positive engagement with the latter and can be actuated together, so that the actuation of the two is virtually interlocked actuators are carried out synchronously.
  • the actuators are preferably designed as a rocker switch, which is advantageous in view of the desired low overall height or depth.
  • a first arrangement 10 of each formed as a rocker switch 12, 14 for an electrical switching device, not shown, with three switch poles arranged in switching tracks is shown in an oblique view, the switching contacts arranged in the switching tracks are actuated by switching cams 18 which are actuated on the Shift paddles 12, 14 are formed.
  • a plug-in axis 20 which extends through all the shift paddles 12, 14.
  • coaxial pins 22 are formed, which have corresponding indentations on the associated housing of the switching device, which is also not shown or recesses, which serve as guides, work together and thereby form the pivot bearing of the rocker switches 12, 14.
  • the respective outer wall is formed continuously on the shift paddles 12 located on the outside and serves both as a shaping surface for the pins 22 and as a boundary for blind hole-like recesses 24, in which the plug-in axis 20 engages from the inside.
  • the plug-in axis 20 prevents the pins 22 and thus the rocker switches 12, 16 from sliding out of the guides on the housing.
  • FIG 3 and 4 each show a second arrangement 11 of shift paddles 12, 13 according to the invention, in which a shift paddle 12 is designed as described above, while a second rocker switch 16 is provided with a coaxial projection 17, which is similar is formed a hollow cylinder and the length of which corresponds to the width of a central rocker switch 14.
  • This design of the rocker switches 12, 16 enables the separate actuation of a switch pole and the joint actuation of the other two switch poles in the three-pole switching device on which the switch is based.
  • a plug-in axis 20 is provided which coaxially extends through the shift paddles 12, 16, including the cylindrical projection 17, the recesses 24 in the shift paddles 12, 16 each being designed in a blind hole-like manner.
  • a third arrangement of shift paddles 12 according to the invention is shown which largely corresponds to the first arrangement. Unlike there, however, the middle rocker switch 14 is omitted, while the outer rocker switches 12 are present in an identical design to that shown in the first arrangement 10.
  • connection contacts of the middle switching path are assigned to an outer switching path, so that whose electrical supply takes place by actuating the relevant switch contact.
  • rocker switches 12, 14, 16 It applies to all rocker switches 12, 14, 16 that they are box-shaped, their actuating side being open in each case. A cover, not shown here, can be placed on the assigned shift paddles 12, 14, 16. As shown in the exemplary embodiments, the size of the rocker switches 12, 14, 16 can be different in accordance with the intended installation geometry.
