Definitions
- the invention relates to a switching device with a position or status display, with the position or state of the switching device, preferably an electrical one Miniature circuit breaker, residual current circuit breaker and the like is displayed after the preamble of claim 1.
- circuit breakers For currently known circuit breakers, there is a requirement that the circuit breaker must have so-called separator properties, whereby it must be indicated that the contact pieces are actually opened during a switching operation. For the In the event that contact welding of the contact pieces occurs and thus opening the contact point cannot be reached, the circuit breaker toggle must between the on position and the off position in a middle position stop. With certain switchgear it is not possible to use the switch lock or to design the switch so that the switch toggle is in the middle position remains.
- the object of the invention is to provide a simple display of the type mentioned with which it is reliably displayed whether the contact pieces are welded and therefore cannot reach the switch-off position.
- the switch position indicator ON-OFF is more common by the actuator Displayed way; if a push button is provided as the actuating element, then the push button actuation area is just above in the switched-on position the push button has jumped out of the front surface and in the off position clearly overlooks the front wall.
- the switching device is triggered, i. H. the trigger has released the rear derailleur, and if the contact point does not open due to welding and that Actuator remains in the ON position, then the double arm lever displayed this triggering.
- a push button as an actuating element, it is located on the push button advantageously a nose and a projection on the first arm, one below the other cooperate in such a way that the double arm lever again when switched on is deferred.
- An electrical switching device 10 which is a circuit breaker, has a magnetic Trigger 11, which is designed as a submersible anchor trigger, the submersible anchor 12 is only drawn schematically and only partially.
- the diving anchor 12 triggers in the event of a trip, that is to say when a short circuit occurs a release lever 13, which is in a fixed bearing 14, which is above the Trigger 11 is pivoted; the trigger lever 13 acts on a not shown Switch lock, which is omitted in the drawing because it is for the invention doesn't matter.
- the plunger anchor 12 moves in the event of a trigger according to the direction of the arrow 15 in the drawing to the left, so that the trigger lever 13 clockwise is pivoted and acts on the switch lock.
- a double arm lever 17 pivotable about an axis of rotation 18, the first arm 19 of the double arm lever a projection extending into the path of movement of the plunger anchor 12 20 has; the second arm 21 of the double arm lever has on its free End a flag 22, which is marked with different colors and which is in front of you Window 23 is pivoted back and forth in the front wall 16.
- the double arm lever 17 extends approximately perpendicular to the front wall 16 and that in addition the first arm 19 is approximately half as long as the second arm 21. This ensures that the relatively short movement distance of the plunger anchor 12 is converted into a larger path of movement of the flag 22.
- the actuating element 24 of the circuit breaker is a push button located in 1 in the on position and in FIG. 2 in the off position.
- the push button 24 has a nose 25 with a projection 26 on the molding 20 cooperates; the projection 26 is in the path of movement of the nose 25, regardless of the position of the double arm lever.
- a compression spring presses against the free end of the first arm 20 of the double arm lever 27; the line of action of the pressure force of the compression spring 27 runs on one side of the Axis 18 in the switched-on position according to FIG. 1 over, in such a way that it is the double arm lever constantly tries to pivot counterclockwise; in the 1 is the first stable position of the double arm lever 17.
- the helical compression spring 27 is guided with its other end in a fixed position in a bearing 28.
- Fig. 1 shows the switch-on position; the double arm lever 17 is thus below of the window that the area of the flag 22 located on the right in FIG the window comes to lie.
- a thermal tripping device 29 is assigned to the circuit breaker 10, which has a bimetallic 30, which is also on the latching point in the rear derailleur can act.
- FIG. 2 shows the arrangement in the off position: the push button 24 has jumped out, which is due to the thermal release device 29.
- the double arm lever 17 is in the position shown in FIG. 1.
- FIG. 3 shows the arrangement in the release position.
- the diving anchor 12 has moves from the release 11 to the position 12a due to a short circuit, whereby on the one hand the trigger lever 13 and the trigger lever 13 and the molding 20 on the other hand, the double-arm lever 17 is pivoted into the release position 3, in which the left end of the flag 25 shown in FIG. 3 closes under the window 23 comes to lie.
- the line of action of the compression spring 27 now runs in the drawing in FIG. 3 to the left of the axis of rotation 18, so that by the compressive force of the compression spring 27 Double arm lever 17 is spring loaded clockwise; the execution according to 3 is then the second stable position of the double arm lever 17.
- the projection 26 touches the nose 25 and it can be seen that the push button 24 extends just as far the front wall 16 protrudes, as is the case in the switched-on position according to FIG. 1 is. 3 is the release position before the push button 2 reaches the switch-off position.
- the double arm lever is located 17 in the position shown in FIG. 3; due to the non-opening of the contact pieces
- the push button 24 remains in the position shown in FIG. 3. This means that the switch has tripped but not opened, which indicates a defect in a contact weld lets close.
- the push button becomes complete from the position shown in FIG. 3 pressed into the front front wall 16, whereby the nose 25 over the projection 26 the double arm lever 17 pivoted counterclockwise so far that the Dead center position between the two stable positions (FIGS. 1 and 3) exceeded is so that the compression spring 27, the double arm lever 17 again in that shown in Fig. 1 Position can pivot.
