The invention relates to a multiple switch with a row arranged side by side and to one Switch unit of combined push-button switches, as used in electrical or electronic devices Performing the switching operations can be used for a plurality 5 of circuits.

The aim of the invention is to provide a simply constructed multiple switch, which for the most diverse Purposes. Above all, the switch should be constructed so that it can be operated in a simple manner can be manufactured, assembled and, if necessary, repaired.

There is already a switch unit known, which consists of several, arranged side by side and on one common bracket attached push-button switches, the key slider part of the Bracket, namely a panel, enforce. Here, the switch housing with the bracket are known Way screwed. This usual type of fastening is too expensive for mass production.

Furthermore, a multiple switch is known, with a number of parallel side by side and to one Switch unit combined push-button switches, the housing of which one for the purpose of fixing their mutual Have position in each a slot or the like recess insertable part. Even these switches are held together by means of a rod or a threaded bolt.

Based on this prior art, a multiple switch is developed according to the present invention proposed of the type indicated above, in which the slots or the like recesses in a connecting rail common to the switch housings is arranged and the inserted Switch housing attached by at least one with the rail integral, bendable locking part are. In such an arrangement, the individual switch housings are exclusively from the common Worn rail, in which they are easily inserted in order to be in their end position to be locked by means of a bendable locking part. This makes a simple and solid one Holder of the switch housing od without the use of screws. The like. Achieved.

This arrangement is particularly advantageous for printed circuit technology suitable. The very simple installation of the switches enables extremely short connecting lines, which is particularly important for devices operated in the HF range, as well as very economical use of the available space.

Since you have multiple switches on one and the same connecting rail

can attach any number of switch housings, with the single push button switch in turn can contain any number of switch contacts actuated by a button, and there also the switches on the rail in any order and with almost any space can be arranged, the multiple switch is suitable for all possible purposes suitable.

According to one embodiment of the subject matter of the invention, the switches are each by means of a a movable contact carrier actuating button controllable and have an existing insulating material Housing on, the cross section of which is perpendicular to the axis of displacement of the movable contacts in the vicinity of at least one of the ends of the housing is approximately rectangular, the connecting rail consists of a U-shaped metal profile which surrounds and locks the ends of the switch housing and is provided with passage openings for the movable contact carriers on its front side.

In a further development of the subject matter of the invention, the interacting recesses are in the connecting rail and insertable parts of the switch housing designed like a bayonet lock. One Such an arrangement allows a very quick assembly of the switch, the individual switches with respect to the rail by means of a deformable tab arranged on the rail. For this purpose, the switch housing of the multiple switch according to the invention can at least

Switch housing shorter than the depth of the U-shaped connecting rail 6 (see FIG is available. A longitudinally displaceable locking element 28, which is provided with recesses 3O ₁ , 3O ₂ and 3O ₃ (cf. FIG. 6) for receiving the free ends of the contact carriers 9, can be accommodated in this intermediate space.

By means of such a lock, certain switches, e.g. B. the switches I ₁ and 2 ₂ are coupled to each other in a certain way. For this purpose, the free end of its contact carrier 9 is provided with ramp-like incisions 32 (cf.Fig. 2, 7 and 8) with which _{noses 34 t} , 34 _{2 arranged in the recesses 3O 1} , 3O ₂ and used for locking cooperate.

Fig. 6) is shifted and the other contact carrier (see Fig. 8), if it is pressed in, is released. Thus, pressing one button unlocks the other button.

In the case of the one shown in FIG. Example shown 2 and 6 is not coupled to the switch 2 ₃ with the adjacent, as its corresponding aperture 3O ₃ is not equipped with a locking lug 34th In this case, this switch has its own device for locking in one or the other of its two positions.
