Definitions

the invention is in the field of electrical switches, which with a switching shaft coupled to a drive for Moving equipped at least one movable contact are, and is in the constructive design of a key switch applicable for latching the selector shaft.
a known such electrical switch in which the Switch shaft via a drive train against the force at least a spring from an OFF position to an ON position is transferable, has a key switch, at which is a pivotable first coupled to the drive train Lever on a stop held in a latched position is supported.
a key switch at which is a pivotable first coupled to the drive train Lever on a stop held in a latched position is supported.
two tripping processes are provided. So the transfer of the stop in his Release position on the one hand by a "normal" triggering process, at which the stop is actuated directly.
a second lever is provided for the key switch is the work surface assigned to the stop having.
the second lever is at least one second spring in a first stop position on the first Lever held.
the second lever is used in this known switch lock and two of the second springs not only for pivoting the stop but also for coupling the drive train with the first lever.
the force of the first spring therefore acts indirectly over the second lever and the second springs on the first lever.
the force of the first spring acts, so to speak Row to the force of the second springs on the first lever. Due to the double function of the second lever and the second
spring is the pivoting of the second lever and thus the "accelerated” release process depending on the sequence of movements the drivetrain and on the other hand is the "normal” triggering process depending on the design of the second lever and the second springs.
this object is achieved in that the forces of the two springs are independent of each other on the first lever.
Such a design can ensure that the second spring is not used to couple the first lever with the drive train.
the power of the second spring acts as it were not in a row but in parallel the force of the first spring on the first lever.
This configuration has the advantage of providing the initiating Force to pivot the first lever initiating Means or an initiating mechanism can be chosen can, the transmission links of the drive train or the coupling of the drive train with the first lever in such a way "skips" that the second lever out faster than that the switching lock known from US Pat. No. 6,018,284 swings.
This configuration also has the advantage that by actuating the stop using a release line essentially caused "normal” triggering not on the design of the second lever and the design depends on the second spring.
the second lever on the first lever is pivotally mounted and the path of movement of the second lever limited by two stop surfaces of the first lever is.
the initiating lever can be used to pivot the second lever Force of a magnetic release or the force of a Serve spring.
FIG 1 shows an electrical switch 1 in the form of a Low-voltage circuit breakers with a switch contact system and an associated arc extinguishing chamber 2.
Das Switch contact system consists of a fixed switch contact arrangement 3 and a movable switch contact arrangement 4.
the movable switch contact arrangement 4 has a pivotable contact carrier 5 and a plurality of contact levers 6 on, the contact lever 6 pivotable parallel to each other and by means of first springs 7 under tension on the Contact carrier 5 are supported.
the movable switch contact arrangement 4 is in a known manner over one in the figure 1 only schematically indicated lever arrangement 8 (see also FIG 2) coupled to a switching shaft 9.
the selector shaft 9 serves at the same time to drive not shown, arranged in parallel to the switching contact system shown further switch contact systems.
a drive device 12 from an AUS position, in which the Switch contact system is open, in an ON position at which the switch contact system is closed to transfer.
the drive device 12 has one provided with a spring mechanism 18 drive 19, a the drive 19 coupling with the control shaft 9 drive train 15 and a key switch 17.
the castle 17 has two latching devices in a known manner, a first of which is used to latch the tensioned spring mechanism 18 and the second for latching against the force of the first springs 7 into their ON position shift shaft 9 serves.
the second latching device has the key switch one coupled to the drive train 15 first lever 21, a second lever 22 and a as Half-wave formed stop 23.
the first lever 21 consists of two parallel to each other at a distance from each other arranged partial levers and is around a first pivot bearing 25 pivotable, which on a support device 14 for the Drive device 12 is held stationary.
the first lever is in the locked ON position of the control shaft 9 with a latch surface 24 under the force of the first springs 7 on the stop 23.
With a "normal" triggering process there is no actuation of the stop 23 trip line shown, for example by hand a push button 10 or arranged on the front of the switch by an electromagnet 11.
the second lever 22 is around one second pivot bearing 26 pivotable, the second pivot bearing 26 is formed by a bolt at its ends is held by the two partial levers of the first lever 21.
Around the second lever 22 in a stop position on the first Holding lever 21 is on the one hand as a relative spring second spring arranged between the two levers 21 and 22 28 and on the other a pin-slot connection is provided.
a pin formed on the first lever 21 engages 29 into an elongated hole 30 formed in the second lever, the two ends of the elongated hole each have a stop surface Form 31 and 32 for pin 29.
One end 35 the second spring 28 engages over a nose 36 of the second lever 22.
the other end 37 of the second spring 28 is on projections 38 the partial lever of the first lever 21 is supported.
the second lever 22 is under the initiating Force F of the initiating means 41 against the Force of the second spring 28 so counterclockwise pivoted that its ramp-like work surface 40 on the flat underside 42 of the half-wave slides along with it the half-wave rotates clockwise and into its release position transferred.
the drive train 15 and the Switch shaft 9 its support on the half-wave and the Shift shaft 9 is under the force of the first springs 7 in their OFF position transferred.
the first lever 21 its Has lost support on the half-wave and begins under swiveling through the half wave also carries the initiating Force F and the force of the second spring 28 for acceleration of the first lever 21 so that the selector shaft 9 reaches its OFF position very quickly.
