  • the Additional switches For connection to electrical display devices, the Additional switches a pair with three terminals 25, 26, 27 and 28, 29, 30, with the connecting terminals 25, 26 and 28, 29 with contacts 31, 32 and 33, 34 fixed to the housing are connected.
  • the terminals 27 and 30 are movable Contacts 35 and 36 electrically connected.
  • the switching mechanism of the additional switch has a signal lever 5 and a contact lever 4 on a common Axis 36 are mounted in the housing. On the same axis 36 and between the signal lever 5 and the contact lever 4 is one Pawl support 6, which is supported by a bolt 21 or 21 ' with the switching mechanism of the electrical circuit breaker can be connected. Depending on whether the additional switch is on the left or right side of the circuit breaker should be, the unneeded bolt 21 or 21 'on the opposite side.
  • the contact lever 4 is composed of a toggle lever Pawl 7 and a bracket 11 connected to an actuating button 3, which in turn has a button pin 22 with the actuating button of the circuit breaker can be connected.
  • the Jack 7 is on the one hand with the bracket 11 and on the other hand with the contact lever 4 connected via a joint 12 (Fig. 5).
  • the Actuating button 3 is also assigned a button spring 17, the one leg with a test button 9 on the lower shell 1 and with the other leg on the operating button 3 supports and this counterclockwise, i.e. into the exhibition, which e.g. is shown in Fig. 1.
  • FIG. 5 is essentially the same as FIG. 1 Embodiment of the additional switch shown, in which the Signal lever 5 is shown in the removed position and which shows the additional switch in the ON position.
  • the bolt 21 or 21 ' then protrudes through slit 44-like slits in the carrier 4 or 45 in signal lever 5 and through corresponding slots in the upper shell 2 or the lower shell 1 to the outside and through corresponding recesses in the circuit breaker and is there connected to its switching mechanism.
  • the circuit breaker is caused by an electrical fault condition triggered, the movement of its switching mechanism is over transfer the bolt 21 or 21 'to the jack support 6, which pivots this counterclockwise and the Detent connection with the pawl 7 is released, causing the toggle lever 7, 11 buckles and the contact lever 4 under the effect the tension spring 16 is pivoted clockwise.
  • the contact lever 4 has an approach 46 and the signal lever 5 on a nose 47, which when pivoting of the contact lever 4 counterclockwise in the system come together, causing the signal lever 5 from the contact lever 4 is taken along and a tension spring 16 'between the Signal lever 5 and the lower shell 1 is biased.
  • a locking projection 50 is arranged, which with the locking projection 51 of a lock 8 cooperates, i.e. With you hooked when the signal lever 5 is in its ON position has (see Fig. 4).
  • the lock 8 is on a housing-fixed Bearing 49 pivoted and by a compression spring 19 between an actuating lever 62 of the lock 8 and one fixed to the housing Prestressed receptacle 53 counterclockwise.
  • the lock 8 finally also has a trigger lever arm 54 on, which has a bend 55 at its end, which with the toggle lever consisting of pawl 7 and bracket 11 cooperates, such as. 4 and 5 can be seen.
  • the contact lever 4 acts on the leaf spring 56 and on the Leaf spring 57 acts on the signal lever 5 in such a way that the Leaf spring 56 from the contact lever 4 in the OFF position against the fixed contact 33 and in the ON position against the fixed Contact 34 is pressed and that the movable contact 35 from Signal lever 5 in the ON position against the fixed contact 32 and pressed against the fixed contact 31 in the OFF position becomes.
  • the leaf spring 56 on the contact lever 4 is between two Lugs 58 and 59 and the leaf spring 57 on the signal lever 5 added between approaches 60 and 61.
  • the movable contacts are 35, 36 in the electrical OFF position, i.e. when through an electrical fault condition caused by the circuit breaker were actuated on the two contacts on the left, fixed to the housing 31 and 33, whereas in the manual OFF position according to Fig. 3 the movable contact 35 (the signal lever 5) on the right Fixed contact 32 and the movable contact 36 (des Contact lever 4) on the left fixed contact 33. Both movable contacts are in the ON position (FIG. 3) 35, 36 on their assigned, right housing-fixed contacts 32, 34. In this way, is possible in a simple way a corresponding switching of contacts 31 to 36, i.e. about the associated terminals 25 to 30, the respective Circuit status of the circuit breaker or the cause of determine its switching off.
  • the lock 8 is completely deactivated, i.e. the signal lever 5 always, i.e. regardless of the type of triggering, accordingly the contact lever 4 is moved.
  • the control lever 62 of the lock 8 in Housing assigned an eccentric shaft 10 in the in the Figures shown position the movement of the lock 8 not obstructed counterclockwise.
  • the eccentric shaft 63 rotated by at least 90 °, as in FIG. 5 is shown in dashed lines, it rotates the lock 8 over whose adjusting lever 62 so far that it no longer with the Signal lever 5 can latch, making the lock 8 easy Way is disabled.
  • To adjust the Eccentric shaft 10 has a slot 66 for e.g. one Screwdriver on.
  • a signal arm 64 is also arranged on the signal lever 5 in the area of an opening 65 at the top of the lower shell 1 arrives when the signal lever is in the OFF position lies, so that a simple optical directly at the additional switch Control is given, whether an electrical or manual release is present.
  • a test button 9 arranged by the button spring 17 after is loaded outside and the pawl support 6 over their Extension 52 actuated, i.e. swiveled clockwise and thus releases the toggle lever 7, 11 when it is turned inwards or is pressed down.
  • the Leaf springs 56, 57 with the movable contacts 35 and 36 have different shapes.
  • a problem with circuit breakers or the ones assigned to them Auxiliary switches is that the switches are the largest part their operating time in the ON or OFF position, so that the open contacts oxidize and thus an increased Have resistance when closing.
  • the invention is therefore provided that after the movable Contacts 35, 36 on the leaf springs 56, 57 from the contact lever 4 and the signal lever 5 were moved so far that they rest on the fixed contacts 31, 33, the signal lever 5 and the contact lever 4 a little more, about 1 ° to 5 °, preferably be pivoted about 2 ° to 3 °, whereby the leaf spring 56 somewhat stretched and the leaf spring 57 somewhat is further bent. This leads to a relative movement, i.e.
  • Frictional movement, between the moving contacts 35, 36 and the contacts 32, 34 fixed to the housing can also be used with the contacts fixed to the housing 31, 33, i.e. the contacts of the respective OFF position be. This relative movement reduces one Keep contacting by oxidizing.
  • the invention can be as follows, for example being represented:
  • the additional switch for mounting on electrical circuit breakers has two movable electrical contacts 35, 36, which in each case two fixed, electrical contacts 31, 32, 33, 34 assigned.
  • the movable electrical contacts 35, 36 are actuated by a signal lever 5 and a contact lever 4, an actuating button 3 via a toggle lever 7, 11 is connected to the contact lever 4.
  • the operating button 3 can be connected to the operating button of the circuit breaker.
  • a jack pad 6, which with the switching mechanism of the Circuit breaker is connectable, is used to trigger the signal lever 5 and / or the contact lever 4.
  • One arm of the knee lever 7, 11 is formed by a pawl 7, which is switched on State of the additional switch hooked with the jack support 6.
  • the Lock 8 has an adjusting lever 62, which one in the housing 1, 2 stored actuator (eccentric shaft) 10 assigned is, via which the lock 8 is fixed in one position can be in which they do not lock with the signal lever 5 can.
