Definitions
- FIG. 4 shows the switch of FIG. 3 in the ON position
- a latching projection 50 Arranged on the signal lever 5 is a latching projection 50 which interacts with the latching projection 51 of a lock 8, i.e. hooked with it when the signal lever 5 has reached its ON position (see FIG. 4).
- the lock 8 is pivotally mounted on a bearing 49 which is fixed to the housing and is biased counterclockwise by a compression spring 19 between an actuating lever 62 of the lock 8 and a receptacle 53 fixed to the housing.
- the circuit breaker is "electrically" as described above, ie triggered by a fault condition in the circuit to be protected by the circuit breaker, its switching mechanism actuates the circuit breaker Pawl support 6 counterclockwise, whereby the knee lever 7, 11 bends upwards and the lock 8 rotates clockwise via the attachment 55 on the lever 54, so that the latching connection 50, 51 between the lock 8 and the signal lever 5 is released even before the signal lever 5 can rotate together with the contact lever 4 by a significant amount. After the latching connection 50, 51 has been released, both the contact lever 4 and the signal lever 5 can pivot freely clockwise to the right.
- the contact lever 4 acts on the leaf spring 56 and the signal lever 5 acts on the leaf spring 57 in such a way that the leaf spring 56 is pressed by the contact lever 4 against the fixed contact 33 in the OFF position and against the fixed contact 34 in the ON position and that the movable contact 35 is pressed by the signal lever 5 in the ON position against the fixed contact 32 and in the OFF position against the fixed contact 31.
- the lock 8 is fixed in its clockwise position, in which it cannot lock with the signal lever 5.
- the control lever 62 of the lock 8 in the housing is assigned an eccentric shaft 10 which, in the position shown in the figures, does not hinder the movement of the lock 8 counterclockwise.
- the eccentric shaft 63 is rotated by at least 90 °, as shown in dashed lines in FIG. 5, it rotates the lock 8 via its adjusting lever 62 to such an extent that it can no longer latch with the signal lever 5, as a result of which the lock 8 is put out of function in a simple manner.
- this has a slot 66 for e.g. a screwdriver.
- a signal arm 64 is also arranged on the signal lever 5, which reaches the area of an opening 65 at the top of the lower shell 1 when the signal lever is in the OFF position, so that a simple visual check is made directly on the additional switch as to whether there is an electrical or manual release.
- a problem with circuit breakers or the additional switches assigned to them is that the switches are in the ON or OFF position for the majority of their operating time, so that the open contacts oxidize and thus have an increased resistance when closing.
- the signal lever 5 and the contact lever 4 are pivoted a little further, about 1 ° to 5 °, preferably about 2 ° to 3 °, whereby the leaf spring 56 is somewhat stretched and the leaf spring 57 is bent a little further. This leads to a relative movement, i.e.
- Frictional movement between the movable contacts 35, 36 and the contacts 32, 34 fixed to the housing. The same can also be done with the opposite contacts 31, 33, i.e. the contacts of the respective OFF position. This relative movement prevents reduced contacting by oxidizing.
- a lock 8 which can prevent the movement of the signal lever 4 when the additional switch is triggered via the actuation button 3 (on the signal lever 5 there is a latching projection 50, on which a corresponding latching projection 51 can hook on the lock 8) mounted on the housing 1 and movable by the toggle lever 7, 11 from the position preventing the triggering of the signal lever 5 when the additional switch is triggered by the circuit breaker via the jack support 6.
- the lock 8 has an actuating lever 62, to which an actuating device (eccentric shaft) 10 mounted in the housing 1, 2 is assigned, via which the lock 8 can be fixed in a position in which it cannot latch with the signal lever 5.
