Electrical device with a housing and a slide switch penetrating the housing wall

The invention relates to an electrical device in the preamble of claim 1 specified Art.

In the case of electrical devices that are enclosed by a housing are, is in many cases under the part of the housing wall that one is provided for the controls of the device insulating shuttering sheet with printed lines provided on the adjustable electrical circuit elements, e.g. setting resistors, switches and the like are attached. The controls of this adjustable electrical circuit elements penetrate through openings this housing wall forms the housing, so that the adjustable switching elements arranged inside the housing can be adjusted by an operator outside the housing. The adjustable however, require electrical circuit elements a relatively large distance due to their height the circuit board running approximately parallel to the housing wall to this housing wall. With a very flat one electrical device of the type specified, however, this required minimum distance of the

Circuit board from the housing wall can be very annoying.

The invention is therefore based on the object of a electrical device of the type specified in such a way that despite one between the housing wall and a slide switch disposed on a circuit board provided with printed electric wires the distance between the circuit board and the housing wall can be made very small. This object is achieved according to the invention by the in the characterizing Part of claim 1 specified spatial-technisehen Features solved in an advantageous manner.

By including the housing wall of the device in the guide of the slide switch plate and by simultaneously Use of conductor parts of the lines printed on the circuit board as electrical contacts the slide switch has a very low overall height of the slide switch and thus a very small distance between the circuit board and the housing wall of the device. The measures of claim 4 advantageously further reduce the distance reached between the circuit board and the housing wall of the device. In this case it will be the full Wall thickness of the housing wall of the device for accommodating the between the housing wall and the electrical circuit board arranged switch part of the slide switch exploited.

The invention is based on an advantageous Embodiment explained in more detail. In the this Embodiment schematically depicting drawing demonstrate

Figure 1 is a plan view of the partially cut open Housing wall of the electrical device at the location of the slide switch,

FIG. 2 shows a sectional view along the section line B of the housing part shown in FIG

in the viewing direction A and

FIG. 3 shows a sectional view along the section line D of the housing part shown in FIG in the viewing direction C.

In Figure 1 is a plan view of einxin from the lines 1 and 2 limited section of the housing of an electrical device in place of one in the device arranged slide switch shown. Figures 2 and 3 represent sectional images along the cutting lines B and D of this section represent, in each case from the direction A and C. The housing wall 3 of the electrical device for example a very flat one Remote control device for telecommunications equipment or consumer electronics is included in the illustrated Area on its outside is a cover plate 4. Parallel to the inside 5 of the housing wall 3 is inside of the electrical device, an insulated circuit board 6 is arranged, on its pointing towards the housing wall Page 7 a field of electrical conductor tracks, e.g. 8, 9, 10, 11 is printed on it. The housing wall 3 has two rectangular openings 12 and 13 which are arranged parallel to one another and a narrow one between them Form web 14 in the housing wall. In the larger opening 12 of the housing wall is a switch plate

of the slide switch, which is arranged parallel to the housing wall. At their parallels to the sliding direction The sliding switch plate contains the horizontal narrow sides 16 each has a rounded guide nose 17 on which

the sliding switch plate 15 from the parallel to the sliding direction extending side walls 18 of the opening is guided in the housing wall. To another tour the slide switch plate 15 contains these in one piece attached to it boom 19 a running in the sliding direction guide slot 20 in which a guide pin 21 of the housing wall 3 engages.

In addition, the slide switch plate 15 is also attached
integrally molded a resilient tongue 22, on the
free end of a locking cam 23 is formed. The locking cam rests against a locking pin 24 of the housing wall 3 and, in one switch position of the slide switch, presses the slide switch plate 15 against the side wall of the large opening 12 that is perpendicular to the slide direction and, in the other switch position of the slide switch, against the other side wall of the slide switch perpendicular to the slide direction Breakthrough 12.

On the side facing the insulated switch plate 6 with the printed conductor tracks, the slide switch plate 15 in the illustrated embodiment contains an arm 25 with two each injection molded onto a narrow side 16 lying parallel to the slide direction
cuboid pockets 26 which are open towards the insulated circuit board 6. In each of these pockets 26 a bridge contact spring 27 is inserted, which is shaped so

that they with a spring force with two lying next to each other Contact points 28 and 29 rests with a spring pressure on the insulated circuit board 6 and is on the Bottom 30 of the cuboid pocket against the slide switch plate 15 supports. The contacts of the slide switch are conductor parts, e.g. 8 to 11, which are only at the contact points 28 and 29 of the individual switch positions of the slide switch in the sliding area of the bridge contact springs 27 loungers. In the individual switch positions of the

Slide switches connect the bridge contact springs 27

individual on the insulated circuit board 6 from each other separate conductor tracks electrically, e.g. the conductor tracks 10 with the conductor tracks 11 or the conductor tracks 8 with the conductor tracks 9.

The one provided with the additional bridge contact springs 27 Cantilever 25 of the slide switch plate 15 is in the illustrated embodiment in the smaller rectangular Opening 13 of the housing wall 3 is arranged. The cover plate arranged on the outside of the housing wall 3 4 covers both openings 12 and 13 in the housing wall and only has one integral with it in the displacement area the slide switch plate 15 connected operating handle 31 has a rectangular opening 32 through which the operating handle 31 protrudes. Both the dimensions of the opening 32 of the cover plate 4 as well as the length and width of the slide switch plate T5 are dimensioned so that that in each switch position of the slide switch the outwardly facing side of the slide switch plate 15 from the edges of the opening 32 in the

Cover plate 4 are surmounted.

To a grinding of the slide switch plate 15 or their To largely avoid cantilever 25 on the cover plate 4, is the web 14 between the two rectangular Durchbrücfjen 12 and 13 formed in the housing wall 3 as a sliding element for the slide switch plate 15. The slide switch plate Is under the spring force of the bridge contact springs 27 with the bottom of a groove 33 so against the Web 14 that between the outside of the slide switch plate 15 and the inside of the cover plate 4 is a slight Space remains.

On the other hand, the slide switch plate 15 in the illustrated Embodiment on the after the isolated Circuit board with the side pointing towards the printed conductor tracks as slide cams 34 G Lei te elements on which the stroke when the slide switch is operated limit the bridge contact springs 27 and when pressed the slide switch plate 15 during the adjustment the slide switch on the circuit board 6 the Sliding the slide switch plate 15 facilitated.
