Definitions

  • the invention relates to a time-controlled and / or manually actuable switching lever with a device that can be set by means of a tooth lock to adjust the switching point of an electrical switch for electromechanical timers, cf. DE-U-86 02 885.
  • a switching cam is mounted on a switching lever so as to be longitudinally displaceable, which cam is provided on an inclined plane, for setting the switching point of the electrical switch of an electromechanical timer.
  • a relatively fine-stage tooth lock is provided there between the shift lever and the shift cam.
  • a multi-stage toothing is provided on the shift lever and a spring detent tooth is provided on the shift cam, which engages with the toothing on the shift lever.
  • This adjustment device has the disadvantage that the operability when setting the switching point is complicated and uneconomical due to the spatially relatively small switching cam. In addition, such an adjustment device is not suitable for the same reasons when automatic assembly machines are used.
  • the invention has for its object to provide a shift lever with a device for adjusting the switching point of an electrical switch that is simple, precise and economical to manufacture and simple and economical to operate the switching point both manually and mechanically.
  • the shift lever 1 shown in FIGS. 1 and 2 in any construction-specific embodiment essentially consists of a lever part 1 a equipped with a scanning cam 2 and a lever part 1 mounted on one side on the lever part 1 a, in particular in the region of its bearing point 3, lever arm 1b under the action of a spring force.
  • the lever part 1a and the lever arm 1b are expediently connected to one another in one piece.
  • the lever arm 1b is provided on the front side, in particular on one side, with a projection 5 carrying an internal toothing 4.
  • This inner locking toothing 4 is adjacent to a front locking toothing 6, which is arranged on the lever part 1a.
  • the side 12 of the lever arm 1b which is designed to be resilient, acts on the electrical switch 7 in the present embodiment, as can be seen in more detail in FIG. 3.
  • 8 denotes the bearing shaft of the shift lever 1.
  • Fig. 3 it can be seen how the two toothings 4 and 6 for setting the switching point of the switch 7 are engaged with each other without play.
  • the switch 7 is designed there as a so-called snap contact or microswitch, which has a defined switching point of the switching device provided there. 9 identifies a cam track which can be formed from programmed switching tabs 10, which is scanned by the scanning cam 2 of the shift lever 1 without play.
  • 4 shows a shift lever 1 in which the toothing engagement between the lever part 1a and the lever arm 1b is designed as a so-called crown locking toothing. 4 shows the locking teeth on the lever part 1a and 6 indicates the locking teeth on the lever arm 1b. 3 means the bearing point of the shift lever 1 with a bearing shaft 8.
  • the embodiment of the shift lever 1 according to the invention with the lever arm 1b, which is relatively finely adjustable to the lever part 1a and is pretensioned under the action of a spring force, ensures in its relatively large and clearly dimensionable embodiment a simple, precise and assembly-machine-compatible setting device for the switching point of a switch.
  • shift lever 1 may consist of several individual parts and that the directional locking teeth shown and described may have a different dimension than that shown.
