It should first be mentioned that only those parts of the electrical installation switch are shown in the figures of the drawings are, which are important for the explanation of the invention. For example, the connecting cables for the installation switch, fastening devices on the housing for installation in devices for the sake of simplicity. It should also be said that the missing parts not only have a structure that is known per se, but also assembled in a known way who can.

The installation switch shown in FIGS. 1 to 3 consists essentially of a housing Io and an actuator 11. The housing Io is designed in two parts and has a main part 12 and a housing part 13. In the illustrated embodiment, the main piece 12 and the housing part 13 are screwed together 14 held together. The housing Io has a cup-like receptacle 15 in its interior. of the main piece 12 carries stationary contacts in openings 16, 17 and 18. The contacts 16, 17 and 18 are angular and protrude with their connecting legs 19 from the Gehciuseboden outwards. These legs are used to connect the power lines, with the contact 16 being the neutral conductor is assigned, while the contact 18 is connected to the phase conductor. Contact 17 takes the line from the load to be switched with the installation switch.

The second leg of the contacts 16, 17, 18 - the contact leg 2o - rests on the housing bottom of the housing. The contacts 17 and 18 are arranged in such a way that their contact legs 2o face one another, as can be seen from FIG is. However, as can be seen from the plan view of FIG. 3, the contact legs 2o are still laterally relative to one another offset. This is done so that the legs can be made large enough, and still a sufficient one Have a safe distance from each other. The fixed ones

740835728.11.74

Contacts 16, 17, 18 can start from the area of the parting line 21 between main piece 12 and housing part 13 ir. Recordings in Inside the housing Io can be used.

In the area of the two narrow sides of the rectangular housing Io each have a groove 22 arranged in the interior, these grooves in the direction from the opening surface of the housing Io to the bottom run there. However, the grooves 22 do not extend in the entire longitudinal wall but only in areas, so that ', ν formed at the respective end of the groove counter stop surfaces 23 will. The grooves 22 are designed so long that the actuator 11 in the switched-on position with his Hand contact surface 3o below the opening surface of the Housing Io is at least within this area.

The housing part 13 has, on its inwardly directed side, a guide track 24 which is used to receive a latching control part 25 serves. It should already be mentioned here that in the present embodiment the guide track 24 is extends with one side to the outside of the housing part 13 and there forms an opening 5o in the housing Io.

The actuator 11 is box-shaped and consists also of two parts, namely an "outer handling part 26 and an inner switching part 27. A control lamp 28 is arranged between the switching part and the handling part, the feed lines of which take place via openings 29 in the switching part 27. The handling part 26 has a box top wall 3o and box side walls 31. The two box side walls 31 of the Ilandhabungteiles lying on the end faces 26 are provided with projections 32 lying on their outside, which are arrowhead-shaped in the direction of the top wall of the box Expand 3o up to a maximum height 33, which corresponds approximately to the depth of the grooves 22. This will result in the projections formed a stop surface 34, which in the assembled state of the installation switch xr.it the

740835728.11.74

- 9 already mentioned counter-stop surface 23 cooperates.

As can be seen from Fig. 2, the switching part 27, seen in cross section, is constructed like a U-profile. The middle part of the The U-profile-like switching part forms the base for the box-like actuating element 11.

Handling part 2G and switching part 27 are, as shown in FIG. 2 can be seen, held together by a latching connection 35.

One leg of the U-shaped switching part engages in the assembled state of the installation switch in a recess 52 in the housing Io, and also serves as Guide S3 bet the translational movement of the actuator 11 and housing Io, so that no tilting can occur in the housing when the actuator is moved.

The second leg of the U-profile-like switching part 27 is stranded on its outside with a control cam 36. As best seen from Fig. 4 and 6, the control cam 36 is through a heart-shaped recess 37 and a kidney arti- / formed on island 38. This engages in the control cam 36

O Ras ts expensive td.1 25 with a tenon 39 a. The mode of action this control will be explained later.

A Kor.taktdruckplatte 4o is assigned to the switching part 27, Via the legs 2o of the two stationary contacts 17,18 are in electrically conductive connection with one another. The contact pressure plate 4o is, as FIG. 7 shows, rectangular designed and carries two diagonally opposite touch contacts 54, which with the legs 2o of the stationary contacts 17:18 work together. The contact pressure plate 4o is held at one end of a rectangular cross-section Guide rod 41 and that engages the guide rod through a rectangular opening 42 in the contact pressure plate,., the rectangular opening 42 at the same time as a guide

a sliding movement of the contact pressure plate 4o on the guide rod 41 is used. So that the contact pressure plate 4o cannot slip off the guide rod 41, that is one end of the guide rod 41 is provided with a twist 43 after the contact pressure plate has been attached. This twist 43 is formed in that the free end of the guide rod relative to the guide rod itself by 9o ° is rotated.

^; In the exemplary embodiment according to FIG. 8, the guide rod 41 has a key-like projection 55 at its free end. This key-like approach is formed in that two opposing recesses 56 are arranged on the strip-shaped guide rod 41 shortly before its free end. The contact pressure plate 40 associated with this guide rod 41 has an opening 57 adapted to the key-like projection 55 centrally in its center. By sliding it onto the guide rod and then turning it by 90 °, the contact pressure point is held in the recess 56, but can be moved in the longitudinal direction of the guide rod, so that the contact pressure plate in this position can neither be pulled off the guide rod nor pushed up too far. It should be noted here that when this contact pressure plate is moved inside the housing, it is guided on the inner walls of the housing, as can also be seen in FIG.

The other end of the guide rod 41 has a hook-shaped end 46 and thus engages in an angular channel 44, which is arranged in the switching element 27 and ends there. In the end of the WinkeEcanales 44 in the switching element 27 is on the underside of which a cylinder-like extension 45 is flanged. To the guide rod 41 in the end area of the angled channel hold, lies a compression spring 47, which with its turns

740835728.ii.74

• ■ · <

is arranged around the guide rod 41, around the cylinder-like Approach 45 clamped on.

The contact pressure plate 4o with the guide rod 41 is now so arranged on the switching part 27 that when the actuator 11 moves into the interior of the housing Io the Contact pressure plate touches the two stationary contacts 17, 18 and these are thus in an electrically conductive connection brings together. It should be mentioned here that with one Movement of the actuator 11 into the interior of the housing, the contact pressure plate 4o before the insertion movement of the actuator is over, already with the KontnktschenkeIn 2o of the stationary contacts 17, 18 comes into contact, so that the contact pressure plate is in the remainder of the movement of the Actuating device moves on the guide rod 41. This ensures that on the one hand assembly inaccuracies can be compensated and on the other hand the spring-loaded contact pressure plate always with a certain bias the switched-on position of the installation switch rests on the legs 2o of the contacts 17, 18.

A central compression spring 48 is stretched between the actuating member 11 and the bottom of the housing, so that the actuating member always overcome the compressive force of this central compression spring in the case of an insertion movement into the housing. With one end of the central compression spring 48 is on the leg 2o of the stationary contact 17, while she is on her the other end rests in one of the openings 29 of the switching part 27, this end of the spring being designed in such a way that that its coil diameter is smaller than the remaining coil diameter of the compression spring 48. This makes it possible to hold the central compression spring 48 in the opening 29, wherein at the same time the large coil diameter of the spring 43 is supported on the underside of the switching element. That the end of this with the smaller WiÄ ^ ungsdiameter. Compression spring 48 continues to the inside of the box of the actuator 11 so that the control lamp with its lamp

740835728.11.74

- 12 -

Finally engages in the coils of this spring end. Through this one of the leads of the control lamp 28 is formed. The other lamp connection of the control lamp engages in one a small compression spring 49, which also protrudes through an opening 29 into the inside of the box of the actuating member, this compression spring 49 also has a winding diameter at its cold end, which is smaller than that remaining coil diameter of the compression spring. As soon as the actuator 11 with its contact pressure plate 4o on the , ^ Contacts 17 and 18 rests, the compression spring 49 occurs with the

Leg 2o of the contact 16 in connection, so that the control lamp 28 with the contact 16 in electrically conductive Connection.

As already mentioned, the individual switch positions of the installation switch du-r-h are a snap-in steamer part 25, which is shown in a control cam 36 engages is reached. This now happens as follows. Is from a switching position, as in Fig. 1 shown, assumed, the pin 39 of the locking control member 25 rests in the tip of the heart-shaped recess 37. During an insertion movement of the actuating member 11, the locking control part 25 slides in the guide track 24, with O the pin slides along the side wall of the recess 37.

A guiding movement of the actuating member 11 into the housing Io is only possible until the pin 39 is on the side of the recess 37 facing the tip. At a When the actuating member is released, the pin 39 comes to rest on the kidney-shaped island 38. In this switch position the contact pressure plate 4o is in an electrically conductive connection with the contacts 17, 18. With another Pushing in the actuator, the pin slides, guided by the heart-shaped control cam 36, again to the tip of the recess 37.

If the installation switch is initially equipped as a button, so without a latching control part 25, this can be done with his.

Pin 39 retrospectively when the switch is assembled Guide track 24 and the recess 37 are introduced. An opening 5o on the outside is used for this purpose lies in the area of the guide 24 which ends there. Through this opening, the locking control part 25 can enter the interior of the Installation switch. This insertion movement is possible when the switch is in its on position is because then during the insertion movement of the locking control part of the pin 39 through a channel 51 on Legs of the switching part 27 can be introduced into the recess 37. To prevent the RoEtsteuerglled from accidentally slides back out of the recess into the channel, the channel 51 has a smaller overall depth than the recess 37 so that the locking control part is inserted into the recess 37 with elastic deformation of the pin 39 can be.

The switching part 27 shown in Fig. 4, which has no channel 51, will then be used when the installation switch Designed as a switch from the start and subsequent insertion of the locking control part 25 is not desired is.

It should be noted here that, as shown in FIG. 3, the annular Arrangement of the Kortaktdruckplatte 4o, the guide 53, the contact 16 for the control lamp 28 and the locking control part 25 around the central compression spring 48 enables an almost complete use of the space inside the housing. on the other hand will as the above parts in one common As shown in FIG. 1, the height range of the installation switch is the total height of the installation switch kept small.

In the embodiment shown in FIGS a so-called two-pole switch is shown. When this switch is activated, the multi-line

- 14

740835728.11.74

as well as the phase line are each interrupted or bridged.

The installation rocker shown in this exemplary embodiment again consists essentially of a housing Io and an actuating member 11. The two-part housing Io is hfer but divided such that 4 housing side walls form a rectangular housing body 58, during the Bottom of the housing Io is designed as an insertable housing part 59 ι?). Housing part 59 and housing body 58 are fastened to one another by several snap-in connections 6o, as shown in FIG.

The housing part 59 has openings in which stationary Contacts 61,62 are arranged, with the contacts 61 being live when the switch is switched, for example are, while the contacts 62 are used for return. The contact 61,62 is designed in a cross shape. He stands out with his Middle part out of the housing Io, while the transverse part inside the housing on the housing part designed as a bottom 59 lies. As a result, the contact 61, 62 is secured against being pulled out of the housing via the transverse part. In order to limit the introduction of the contact 61,62 into the interior of the housing and the contact 61,62 on the switching part 59 to set, the middle part has tabs 63 which against projections on the outside of the housing part be pressed (see Fig. 11). As an extension of the middle part there is one on the contacts 61, 62 inside the housing lying bend 64 arranged, the bend 64 in each case according to the housing side wall lying next to it is angled.

The stationary contacts 61,62 are now arranged on the housing part 59 in such a way that two contacts 61 each are provided on one narrow side of the rectangular housing part 59 and two contacts 62 each are provided on the other narrow side.

'' ■. Contacts 61,62 produced are arranged parallel to the respective longitudinal side of the housing part 59 or of the housing body 5 3. This arrangement results in a wedge-shaped receptacle (see FIG. 11) in which

I- a contact pressure plate 73 as described later wis ^

is introduced.

^ [\ The actuator 11 according to the exemplary embodiment of

Fig. 9 to 11 is also designed in two parts and has a handling part 65 and a switching part 66, the are connected to one another by a latching connection. As in the first exemplary embodiment, the land handling part 65 on its narrow sides projections which engage in grooves in the housing Io and the movement of the handling part limit unilaterally. Likewise, between switching part 66 and handling part 65, there is a control lamp 28 and that of it assigned resistor arranged.

The switching part 66 is used as a base for the box-shaped handling part 65 formed. It has a receptacle 67 in which the control lamp 28 and the resistor are accommodated is. The receptacle 67 is connected to the interior of the housing via openings 68. These openings 68 are used for implementation of the leads of the control lamp 28.

A flange 69 is located on the underside of the switch part 66 attached, which is used to guide the actuating member 11 in Housing Io engages in a recess 7o of housing part 50. The control cam is also on the guide flange 69 36 arranged for a latching control part 8o.

In the area of both narrow sides of the switching part 66 there is a T-shaped channel 71, seen in cross section, in which each, a guide rod 72 is inserted. On the guide rod

Around the guide rod 72 lies with its turns a compression spring 74, which is supported on the one hand on the switching part and on the other hand loads the contact pressure plate 73. For fastening the made of a strip-shaped material produced guide rod to the switching part 66, a projection 75 is arranged on the guide rod 72, which is also with engages in the T-shaped channel 71 (see. Fig. 9). ν \ After the guide rod 72 has been inserted into the channel 71

the insertion opening closed by the Ilandhabungteil 65 is pushed over the switch unit 6 6 (see Fig. 11), so that the guide rod against being pulled out to the side

The contact printing pad 73 has, as seen in plan view, a rectangular base. On two opposite sides it has bevels 76 which, as FIG. 11 shows, the contact pressure plate 73 is wedge-shaped, seen in cross section Give shape (see Fig. 11). The bevels 76 are now arranged so that when the Ee is pressed in processing member 11 in the housing Io the shields 7G

Finally, at the bends 64 of the stationary contacts

740835728.11.74

- 17 -

sits. This compression spring let with its free end in one Blind hole 79 of the housing part 59 arranged, wherein the Sackiöuh 79 is to prevent that when the Actuating member in the housing, the compression spring bulges and possibly jumps from the pin 77. About the Compression spring 78, the actuating member 11 is always under the influence of a spring force.

As can be seen from Fig. 9, is to control the

( Λ Switch a detent control part 8o ahead. This detent control part is designed in the manner of a crank, as shown in FIG. 14 Embodiment, cooperates with the control cam 36.

As can be seen from Fig. Io, in the housing part 59 is a Insertion opening 83 is provided through which the latching control part 8o afterwards when the installation switch is assembled can be introduced into the interior of the housing. As an introduction - there is one in the control cam 36 for the pin 82

O opening 84 left blank. Located in the side wall of the housing There is also a guide track 85 for the locking control part, which is designed as a pivot bearing and in which the Zapin 81 engages. During the pivoting movement of the latching control member that occurs when the installation switch is actuated, this is rotatably mounted about the pin 81.

It should be added here that through the openings 68 led out two leads of the control lamp 28 are each led to one of the compression springs 74 (see Fig. 9), and passed from there via an unspecified opening back into the space containing the control lamp and are bent over there. When the switch is switched on, the control lamp receives its voltage via the contact pressure plates 73,

- 18 -

740835728.11.74

- 18 the compression springs 74 and the supply lines.

As FIG. 13 shows, this is also the case in this exemplary embodiment due to the arrangement of the two contact printing plates on the two narrow sides of the housing and the guide flange 69 with the control cam and the detent control part 8o and the compression spring 78 in the middle housing area, the use of space the inside of the case is very large. It should also be said that by arranging the two contact pressure plates, as well as the guide including the control curve in a common height range (see Fig. 9), the height of the installation switch is kept very small.

It should be added that in the second embodiment of an installation switch during assembly, the actuator 11 is inserted from below into the housing Io. That is why there are none on the barking projections 32 Inclined surfaces, as in the first embodiment, are present, which allow insertion of the actuator from above into Housing should facilitate.

The detent control parts are now described in more detail below. As can be seen from Fig. 16, the locking control part 25 has an extension * w at its free end an opening 87 carries. After the latching control part 25 has been inserted into the opening 5o of the switch housing, it is in its guide track 24 is pushed until the pin 39 reaches the control cam 36. Extension 86 is now designed so large that, although the pin 39 lies on the cam 36, it still emerges from the insertion opening 5o of the switch housing protrudes. When the actuating member 11 moves, the pin 39 of the latching control part slides 25 along the control curve 36. During this slide, however, the locking control part 25 also moves in its Guide track 24, so that the extension 86 is also moved. The co-movement of the extension 86 can now

- 19 -

740835728.it.74

be used to mechanically trigger a process, for example, switching on a tent switchgear.

In another embodiment (FIG. 17), the extensions 86 are two adjacent switches Connected to one another via a lever-like coupling linkage 91, the coupling linkage 91 being designed as a two-armed lever is. The coupling linkage 91 is pivotably mounted on an intermediate piece 93, which in turn is attached to the screw connection 14 supporting housing projection is attached.

As can be seen from the combination of FIGS. 1, 6 and 17, the left of the two installation switches in FIG. 17 switched off, i.e. the pin 39 of the locking part 25 lies in the tip of the heart-shaped recess 37, while the right of the two switches is switched on, i.e. the pin 39 of the locking control element 25 rests on the kidney-like one Island 38. When the left switch is switched on, i.e. when its function is pressed, the Pin 39 of the rest control part of this switch is guided along the control cam 36 until the pin 39 is on the kidney-like Island comes to rest. The pin 39 of the latching control part of the right switch, however, slides from the island 38 in the tip of the recess 37.

Since when a switch is switched on, the central Compression spring 48 is tensioned, the alternating switching of the two switches according to FIG. 17 can only be via the switched off switch. When pressing and then releasing the actuator of the switched on Switch, the switching state of the two switches would not change, because the relaxing central compression spring of one switch, the compression spring of the other switch would have to be tensioned. However, this is off Reasons of friction already not possible.

In the embodiment according to FIG Number of switches next to one another, a locking rod 80 being arranged on the switches via intermediate pieces 94 is. This locking rod 88 has angular projections 95 which into the opening 87 of the latching control part 25 can intervene. The switches in Fig. 18 are now arranged such that, provided that the switches are the same Have switching state, the openings 87 of the RaststeuerteHe lie on a line. If this is the case, the locking rods 95 of the locking rod 88 can be inserted into the openings 87

to be introduced. Since then the P.aststeuerteila of the individual Switches can no longer be moved, the switches arranged next to one another are in the respective switching state held so that the switch can no longer be switched via the actuator.

In the embodiment in FIGS. 19 and 2o, oin pivotable locking control member Oo shown. This locking control part also has an extension 86, which is one of their free end shows a coupling opening Ü7 for attachment of additional connecting links. So that the locking control part can easily be introduced into its guide track 85, has the insertion opening 83 in the area of the crank pin 81 a bevel on. Likewise, as can be seen from Fig. 2o, the crank pin 81 beveled. It should be noted here that the introduction opening 83, in the area through the Jier Crank pin 82 is carried out, only as wide as the diameter of the crank pin 32 is. The detent control part is thus also gohaltert via the insertion opening, so that the crank pin 81 does not inadvertently move out of its guideway 85 can slide out. A pulling out of the locking control part is only possible if the one having the guideway Housing wall by the height of the fence on the RasU control member is turned. The locking control member is expediently inserted when the actuating member 11 is pressed in, since then the insertion opening 83 of the housing and dLe

Opening 84 of the control cam of the switching part lie one above the other.

In FIGS. 21 to 23, a latching control part 8o is now shown, on its crank pin 81 a disc-shaped extension approach 89 is flanged. The pin 81 can be introduced into the guide track 9o by virtue of the fact that the guide track has a wedge-shaped insertion opening 96, the smallest part of the insertion opening SG being kept smaller (Ä is the diameter of the crank pin 81. This creates a locking connection 92 through which the Rcö: control part 8o or the pin 81 is gphaltert in its guide track 9o. Guide track 9o, insertion opening 96 and latching connection 92 are shown in phantom next to FIG.

About the disc-shaped extension approach 89 can Connecting members are coupled with the pivoting movement of the locking control part. Since the pivoting movement of the locking control part 8o leads via the coupling pin 81 to a rotary movement of the disc-shaped extension projection 89, can, depending according to whether the connecting member is above or below the Crank pin 81 is arranged on the extension when the extension extension 89 is rotated clockwise the connecting member can be pushed or pulled or moved in the direction of the extension or away from it.

The illustrated forms of teaching are, as already mentioned, only exemplary implementations of the invention, sneezes are not limited thereto. Rather, there are still many things Changes and applications possible. For example, « the contact pressure plate be arranged such that the contact legs between the switching part and the contact pressure plate the contacts 17 and 18 are so that when the actuator is inserted into the housing, a circuit is created the two contacts 17 and 18 are interrupted, but when the actuating member protrudes from the housing, this Circuit would be closed. Likewise, the housing could Io

have several cup-like recordings 15, in which either » Pushbuttons and latching switches can be used and which could be coupled to one another via the extensions 86 and 89, respectively. Likewise, the housing could be placed on both long sides Carry coupling and a mating coupling, which would make it possible to connect individual housings Io in series, as shown in FIGS. 17 and 10, for example. Furthermore, the screw connection 14 could be from the main piece 12 and housing part 13 in the first embodiment "A snap-in or welded connection must be replaced. as well

can on the circumference of the disc-like extension approach 89 a spur toothing can be arranged, which then the rotary movement of the extension approach on a rack transmits. Finally, the extension approach can also widen coupling openings.
