Description

To insert the standing with a remote control available power sources according to the changing needs of the network and facilitate the guard an accurate overview, ^one current network status and to take accordingly informed decisions about the executed switching operations, are known in the reproducing an image of the network so-called dummy and luminous circuit diagrams, namely in the course of the current paths or luminous strips of the same, control and feedback switches, so-called control acknowledgment switches, inserted.

In the main patent application M 20664 VIII b / 21c is already a particularly advantageous control acknowledgment switch for installation in light and Blind switchboards for electrical control rooms using one that can be rotated in both directions, centric handle specified for the acknowledgment and control, which can be rotated in both directions Control ring takes place.

The invention uses this principle; at the same time, it enables the area of application of the Control receipt switch to expand significantly according to the main patent application and represents a special advantageous development and simplification of such switches by z. B. in the Eliminate longitudinally displaceable parts and brackets for this.

The invention relates to a control acknowledgment switch for installation in illuminated and dummy switchboards electrical maintenance or the like using a handle that can be rotated in both directions or Knebels for the acknowledgment and control, which takes place via a control ring that can be rotated in both directions. An improvement over the main patent application takes place according to the invention in that the Handle several switch positions distributed over the entire circumference to acknowledge the individual ones Remote control operations are assigned so that the Ouittungsgriff in both directions from each Switch position can be rotated as far as you want.

In this way, a particularly high-quality, simplified one in electrical and mechanical terms Control Ouittungsschalter created for small control rooms, the extremely small dimensions of z. B. about 15.0 x 3.5 x 3.5 cm and its particular advantage is that its operation with respect to the direction of rotation and the starting position remains independent of the mechanical installation, with Incorrect switching is excluded.

For the individual positions of the acknowledgment handle is according to the invention a common detent, in particular one on the one facing away from the handles Roller detent attached to the end of the switch provided, control acknowledgment switch for installation

in illuminated and blind switchboards

electrical maintenance or the like

Carl Seidel, Berlin-Britz,
has been named as the inventor

where rollers are used in spring-loaded girders.

On the other hand, there is generally no latching in the control acknowledgment switch according to the invention the control contacts must be provided or required in the zero position, thereby further simplifying and reduction of the dimensions also compared to the subject matter of the main patent application is brought about.

According to a further proposal according to the invention two telephone lamps are assigned to the acknowledgment handle, which light up together or alternately and, in the latter case, result in different colored illuminated signs.

Further important precautions and details within the meaning of the invention, possible uses and combinations! and advantages of the subject matter of the invention are explained below with reference to an embodiment shown in the drawing; in the drawing shows

Fig. 1 the control Ouittungsschalter in front view,

2 shows the same switch with the cover removed in a plan view, partly in longitudinal section, and FIGS. 3 to 5 show the switch in different sections, namely along line AB or CD or EF in FIG. 2.

1 with an acknowledgment toggle is designated. In contrast to the acknowledgment toggle that can only be rotated 90 ° in both directions according to the main patent application M 20664 VIIIb / 21c is the one given here Acknowledgment indicator 1 can be rotated as required in both directions over the entire circumference and has several, e.g. B. four equally spaced z. B. of 90 ° from each other or against each other offset switch positions on. Concentric to the central acknowledgment toggle 1 is a for the Control serving control handle 2 is provided, as well as the control handle according to the main patent application M 20664 VIIIb / 21 c, can be rotated 45 ° to the left and right, but not locked in the Has zero position.

The toggle 1 is provided on a pull-out, incisions having ring 11, which is in a metal, rotatable inner sleeve 12 introduced and with her by means of inwardly bent, the named Incisions in the ring 11 adapted tabs in the inserted state of the ring 11 with the Inner sleeve 12 is mechanically coupled. The face of the ring 11 is through a transparent or covered translucent material.

The inner socket 12 accommodates a resilient contact plate having lamp holder 9, in which, as known per se, telephone plug-in lamps 7, T are used, which are accessible at any time by removing (pulling out) the ring 11 with the acknowledgment toggle 1. Depending on the arrangement and switching of the contacts assigned to the toggle 1, the two telephone lamps 7, T are switched on either together, i.e. simultaneously, or alternately, in the latter case they are of different colors due to the corresponding coloration of the lamps or the window materials in the ring 11 Illuminated signs on the knob 1 result and thereby increase the security of the monitoring or result in a refinement of the same.

The inner socket 12 together with the lamp holder 9 is extended on the side facing away from the toggle 1 to form a roller 5 made of insulating material or connected to such a roller. Such a roller is composed of individual packets or _v rings are used between which the spring contacts 14 which cooperate with attached to the Schalterisolierwandungen 15 diameters sixteenth The insulating walls 15 carry terminals. 19th

At the end of the roller 15 a roller grid 6 (Fig. 3) is provided. The roller grid consists of a recessed square shaft stub 5 'of the roller 5, which cooperates with a roller 17, which is mounted in a cross-sectionally U-shaped pivotable support piece 18, which, via springs, with a second pivotable, U-shaped support piece 18 'which also carries a roller is, but the pivot point is on the other side of the stub shaft 5 ', so that the Acknowledgment toggle 1 and the movable contacts assigned to it in each switch position, namely in the illustrated embodiment, after each rotation through 90 °, effectively locked by the rollers 17 will. The number of individual switch positions is selected depending on the requirement, so that on Place of four, for example two, six or eight switch positions can be provided,

The metal control ring 3 is pushed onto the inner sleeve 12 and is rotatable about this, wherein it is enclosed by an outer insulating sleeve or tube 30. The insulating sleeve 30 is provided on its circumference with contacts 28 (FIG. 5) which are offset from one another by 180 ° and which are fixed Counter-contacts 29, which are connected to the connections 31, work together.

The control ring 3, however, in contrast to one in known control acknowledgment switches, not to be pushed or moved in the longitudinal direction, so that any additional brackets fall away; a latching in the zero or initial position of the movable control contacts 28 is not present in the illustrated embodiment. ■

The control ring 3 or its extension 1 || protruding from the insulating material bushing 30 at its Etffe facing the acknowledgment contacts 14, 16, but surrounded indirectly or directly by a single helical or omega spring 32, which when the control ring 3 is rotated and thus when switching the movable control contact parts 28 tensioned and when the control handle or -knebeis 2 is released, the control ring 3 with the insulating material bushing 30 and the control contacts 28 provided on this automatically returns to the starting or zero position. This inevitably avoids incorrect switching or control, which can arise from the fact that the attendant is called off while the control is being carried out and forgets to put the control knob 2 in its output ibßw. Move back to zero position. "-: ■■■■■■

The ends 33, 34 of the omega spring 32 are bent so that they are connected to an insulating material bushing surrounding the control ring 3 and an opposite one Support plate 36 attached driving pin 35 work together and also stops with a fixed, e.g. B. almost S-shaped bridge part37 form.

The number of contact springs 14 and knife 16 of the control switch depends on the number of to controlling or switching circuits. . *
