Device for connecting several electrical switches

The innovation relates to a device for connecting several arranged in a row one behind the other electrical switches, whose slide switch for "common actuation älläx" - switch- in against = side engagement.

In the school sector it is necessary for the subject "switching algebra" to arrange several switches one behind the other, their function through the interlocking of the slide switches for all switches at the same time he follows. For more versatile use of the switches, they are not only on their cover side but also on inrer The bottom can be wired, i.e. connections can be plugged on both the top and the bottom will. As a result, it is not possible to mount these switches on a surface to keep them from being mutual Allocation can also be obtained when the switch is actuated.

to create a direction for connecting the switches »which allows individual switches from a network to remove or exchange for another.

According to the innovation, this is achieved in that the switches are connected to one another by at least one flat bar which can be attached to aligned side walls of the switches and which extends transversely to its longitudinal direction, extends from one of its delimiting edges to the other and preferably has undercut grooves, in those on the corresponding side walls of the switches nVia 7.anfan ainsriai fan.

This flat bar allows several switches to be connected to one another to form a unit without impairing the functionality or interchangeability of the switches. The switches assembled in this way are not tied to a solid base, rather they can be carried around while maintaining their unity and, for example, given to other students for viewing or experimentation or the like. Due to the grooves arranged transversely to the longitudinal direction of the flat bar, it is easily possible to remove a switch located in the middle of the switch assembly and to bridge its position with an intermediate member or to replace it with a switch with a different switching function.

An advantageous addition to the innovation results from the fact that the flat bar on its two

Switch groups also arranged parallel to each other and connected to one another to form a unit will.

In addition to the innovation, it is advantageous to that the grooves extend from one delimiting edge of the flat bar to the other delimiting edge extend, whereby the switches can be attached from both sides.

For the stationary support of the switch, it is useful in a further addition to the innovation that the grooves have cams on their opposite groove walls. Liese are beneficial accordingly the dimensions of the pin arranged. Engage in the grooves when inserting the tenons the pegs behind the cam, so that unintentional loosening or loosening is avoided.

In the drawing, exemplary embodiments of the innovation are shown.

In FIG. 1, three switches 1 are connected to one another by flat bars 3 arranged on their two side walls 2. The switches themselves have switching symbols corresponding to the switching function on their visible cover. The switches are connected to one another by the slide switch 4, which has undercut grooves 5 on one side and an undercut connecting pin S on the other side, whereby they can be brought into mutual engagement. On the side walls of the switches 1, undercut connecting pins 7 are arranged, which engage in correspondingly undercut grooves 8 of the flat bars 3. As can be seen from FIG. 2 , the grooves 8 extend from one delimiting edge 9 to almost the other delimiting edge 10. The grooves have cams 11 of small height, by means of which the connecting pins 7 snap into the grooves 8.

According to FIG. 3, the flat bar has undercut grooves 8 on its two long sides, so that switches can be arranged on both sides of this flat bar. In Figure 4 is part of the Flat bar 3 with a groove 8 is shown on an enlarged scale, which has the raised cams 11
