Pushbuttons, control switches or control acknowledgment switches are used to control electrical switching devices. With pushbuttons and control switches devices that provide information about the position of the to be controlled Device, such as switch position indicators (Rückmeider) or ON or OFF lamps additionally required. The control acknowledgment switch, on the other hand, combines all operating functions. For large switchgear It is now often necessary to provide several control points, their functions in parallel lie. So z. B. not only the control of a switching device from the control room, but also from made from the control station of a connected consumer. Often will too In addition to the remote control room, a local control room can be maintained, which can be operated if necessary.

If there are several control points for a switching device, a control acknowledgment switch is often required at one point and to the rest a combination, e.g. B. from a control unit and a switch position indicator, intended. The installation of a further control acknowledgment switch would mean an additional one Increase operating effort (acknowledgment also in the second place), which is often undesirable. on the other hand the arrangement of two devices requires a lot of space and assembly effort.

These disadvantages are to be avoided by the invention on which the object is based to create a simple switching element that has the functions of a switch and a position indicator united in itself., To solve this problem, control switches for electrical devices, in particular, with several control stations for a switching device, proposed according to the invention, in the Control switch to incorporate a position indicator that automatically displays the position of the controlled device. The actuator of the switch should be able to rotate from a position that encompasses the position indicator and / or displaceable sleeve, which have an adjusting device on their front end, in particular an adjusting ring for manual actuation of the switch and on the switching cam for actuation the contacts attached to the position indicator are attached. To establish a specific Movement sequence when operating the switch, the sleeve can have a backdrop while one or more springs act on the sleeve in such a way that it returns to its starting position after each actuation is returned. At the front end of the sleeve, one or more tabs can be provided through which the attachment of the Position indicator serving. Reach through the front panel and an actuator, preferably one Collar / wear. The adjusting ring can be attached to the control switch for electrical devices on the sleeve

be fastened by means of screws. To enable good handling, it is advisable to use the adjusting ring to corrugate on its outside. To be able to observe the indicator of the position indicator, if the collar has a window-like opening. To illuminate the indicator in the position indicator can a. Lamp be provided in or on the switch. On the other hand, you can also use the collar made of transparent material and illuminated from behind.

The difference between the control switch according to the invention and a control acknowledgment switch is more common The design consists in the fact that in the case of the latter, the attendant forcibly quits, i.e. H. Take note must if control was carried out elsewhere. This compulsory acknowledgment is triggered by the new switch is dispensed with, since the built-in position indicator automatically determines the position of its indicator changes. Further features of the invention can be taken from the drawing and the associated description can be removed.

In the drawing, several embodiments according to the invention are shown, namely shows

Figure 1 shows a control switch, which is operated by pulling or pressing the adjusting ring, partially on average,

Fig. 8 a rear view of the control switch according to Fig. 6 and

Fig. 9 a front plate with indicator and adjusting ring. '

The control switch according to Figure 1 is composed of the position indicator 1, a sleeve 2 surrounding it, the adjusting ring 3 and the spring contact sets 4 a and 4 5 attached to the position indicator 5 5, of which one, 5 a, carries a guide pin 5 c for the link 7 of the sleeve 2. The sleeve has at its front end tabs 2 a, which reach through the front plate 8 and to which the adjusting ring 3 is attached by means of screws 3 a. To operate the contacts 4α and 4 5, switching cams 25 and 2c are provided, which work together with the adjusting pins 4 <: and 4d of the contacts 4a and 4 5. The position indicator 1 is held with its front end by a screw-on union ring on the front plate 8, whereby an easier Einzw. Expansion of the combined switch indicator is possible. Springs 6 a and 6 b press against a ring 2 e located in the sleeve 2 and hold it in its initial position. If the adjusting ring 3 is pulled out, the spring 6a is compressed so that the sleeve can return to the position shown in Figure 1 when it is released. When the adjusting ring 3 is pressed in, the spring 65 is compressed and can thus later ensure that the sleeve is returned to its starting position. Depending on the direction in which the sleeve 2 is moved, either the contact 4 a is closed by the switching cam 25 and the associated device is switched on or the contact 4 5 is actuated by the switching cam 2 c. In Figure 2, the backdrop 7 can be seen in which the guide pin 5 c slides.

If the switching on and off is to be effected by a rotary switch, as shown in Figures 3 and 4, a leaf spring 9 or some other spring arrangement that causes it to rotate back is attached to the rear end of the position indicator, which is inserted into a slot 2d of the Sleeve 2 engages in order to rotate it back into its original position after actuation. The switching cams 2 5 and 2 c are arranged so that they come under the adjusting pins 4 c or 4 a ⁷ by turning the sleeve and lift them, as can be seen in Figure 5.

Finally, there is also the option of combining a straight type of movement, namely pulling or pushing, with a rotary movement, as shown by the control switch shown in Figures 6 to 8. The leaf spring 9 attached to the rear end of the position indicator engages in a guide slot 2 d of the sleeve 2 and ensures that the sleeve is turned back into the middle position, while the compression spring 6 a pushes the sleeve 2 back into the starting position after the circuit is complete. The setting causing the movement of the sleeve is designated by 10 in Figure 7. The arrangement of the expensive cams 2 5 and 2 c on the sleeve can be seen clearly from Figure 8 in conjunction with Figure 7.

The partial view of the control panel front or the front plate of the switch shown in Figure 9 shows that indicator la and collar 3 can be monitored well by the operator.

To illuminate the device can be arranged behind the front panel or built into the switch Lamps are used.
