Definitions

  • the invention relates to an overcurrent protection switch of the type described in the preamble of claim 1, as is known for example from German patent 21 23 765.
  • a disadvantage of this conventional single-pole or multi-pole overcurrent protection switch is the lack of a signal contact point, which provides information about the current status of the overcurrent protection switch by means of a signal circuit connected to it.
  • a control box with a large number of so-called on-board circuit breakers may be mentioned here, in which it would be difficult to find the source of the error quickly and accurately without the associated signal lamps indicating a trip.
  • the characterizing features of claim 5 describe a particularly advantageous design of the overcurrent protection switch designed according to the invention.
  • the signal contact point is securely closed by the U-leg of the contact spring, which has a high spring force, when the L-shaped lever is not influenced in the off position of the overcurrent protection switch.
  • the add-on housing Due to the special shape and direction of its components described, the add-on housing also has a high degree of compactness, and can be easily installed in existing switch boxes of conventional design.
  • both the main connections and the signal contact connections can be brought from the same side from behind to the housing, with the rearward opening, angular arrangement of the metal sockets for the electrical leads for the signal contact point can easily be passed to both sides of the main connection wires and connected to the corresponding metal sockets.
  • the overcurrent protection switch 1 has a push button as the actuating element 2 for manual activation or triggering.
  • the main terminal lugs 4 for wiring the main contacts 5 protrude from its insulating housing 3, and the add-on housing 6 with the inserted signal contact point is integrally formed on the overcurrent protection switch 1.
  • the signal contact lever 15 shown in FIGS. 2 and 3 represents the connecting link between the toggle lever 8 and the signal contact point 7. Its stop arm 16 projects into the main switching chamber 17 formed by the insulating housing 3 and is there there by means of a stop projection attached to the joint-side end of the actuating arm 12 18 acted upon in the on position of the toggle lever 8. The stop projection 18 projects beyond the actuating arm 12 in the buckling direction 19 of the toggle lever 8 and its stop side is designed as a convex sliding step 20. This, together with the stop arm 16 of the signal contact lever 15 which is inclined towards the main connection contacts 5, ensures low friction forces to be overcome during the switch-on process.
  • the contact spring 24 is U-shaped, the two U-legs 26 running parallel to the fixed contact 25 and to the direction of the housing depth 13.
  • the U-connecting web 28 of the contact spring 24 faces the horizontal leg 27 of the contact arm 22, the vertical leg 29 of the contact arm 22 acts on the fixed-contact-side U-leg 26 of the contact spring 24 designed as a movement contact and opens the signal contact point 7 in the contact opening direction 30 facing the main switching chamber 17 .
