Definitions
- the invention relates to an electrical switch assembly for installation in a receptacle, the switch except for a cutout for the actuating cap being able to be covered by a cover of the receptacle.
- Tolerances must be provided for the installation of the switches in the receptacle, in particular if several switches are to be installed.
- the position of the aperture belonging to the receptacle can shift relative to this by a certain amount.
- the actuating cap framed by the cover would have to be moved accordingly. This is not possible with conventional switches, however, because the actuating cap is firmly connected to the switch housing again, so that the position of the actuating cap is determined by the position of the switches.
- the size of the aperture for the key cap must be chosen accordingly.
- the actuating cap is located within the aperture, which gives the receptacle fitted with the switches a defective appearance.
- From DE-OS 42 14 974 it is known to mount the actuating cap in a floating manner with respect to the switch housing for the reasons mentioned above. This means that the position of the actuating cap can adapt to the position of the diaphragm opening within certain limits, regardless of the position of the switch.
- the actuating cap is floatingly supported in pins on the switch housing. The base of the cap itself is supported on an actuating member, so that the cap can act indirectly on the switch via the actuating member.
- a disadvantage of the known switch arrangement is that the positional areas between the actuating cap and actuating device on the one hand and the actuating cap and housing on the other hand are relatively far apart, so that undesired tilting moments and material stresses can occur with tolerated production. Furthermore, the actuating device is guided in grooves relative to the actuating cap, so that the actuating device is not held captive relative to the cap.
- a further disadvantage of the known circuit arrangement is seen in the fact that the cap has comparatively large bearing eyes for receiving the housing pins, the edge surface of the bearing eyes simultaneously serving for lateral support of the cap on the aperture of the aperture surrounding the cap. Due to the relatively large contact surfaces of the groove guide and the large contact surface of the eyes on the screen, the movement of the cap is subject to a comparatively large amount of friction.
- the invention is therefore based on a switch arrangement which results from the preamble of claim 1 Genus.
- the object of the invention is to arrange the actuator so that it cannot be lost in relation to the cap and, at the same time, to arrange the bearing points between the cap, actuator and housing in close proximity to one another in order to avoid undesired tilting moments within the switch.
- the object is achieved by the combination of features resulting from the characterizing part of claim 1.
- the invention therefore consists in no longer clamping the actuator between the cap and housing, but instead mounting it directly on the housing.
- the advantage is that just that component is stored in the housing via which the switching forces to be transmitted directly to the switch are applied. Regardless of this, storage of the actuating cap relative to the housing is also provided in a manner known per se.
- the feature combination according to claim 2 is recommended in a further development of the invention. Thereafter, the lever for the force transmitted via both bearings is particularly short and the tilting moments generated are comparatively negligible.
- the construction specified here creates space for the features explained in connection with claim 5.
- the construction between the actuating cap and the actuator is achieved by such a construction, since the part-circular projections are preferably placed in such a way that they require as little stretch as possible for the latching side walls of the actuating cap in the direction of assembly of the two components.
- the feature combination according to claim 4 is recommended in a further development of the invention. Since the cutouts are only part-circular and thus have, for example, the shape of a half ring, Ver remains on the side walls ⁇ extension of the bearing axis of the actuating cap material approximately in the form of a small semicircle. This can be advantageously used for the application of the features listed in claim 5. In this way, the friction resulting from the abutment of the side walls of the cap on the inner wall of the diaphragm opening can be minimized.
- the tip of the projection lies in the extension of the axis of rotation of the actuating cap, so that the projection only rotates, but not swivels, relative to the face of the diaphragm.
- the contact surface of the projections on the diaphragm surface is punctiform, so that here too the friction becomes negligibly small (features according to claim 6).
- the bearing openings of the actuator encompass the stub axle from the outside, so that the actuator can be snapped onto the stub bearing and thus in a simpler manner Way is rotatably mounted.
- stub axles are arranged on the actuator, which snap into corresponding openings in the housing.
- relatively small guide surfaces are then obtained for the part to be spread, which can damage the bearing point.
- a particularly simple form is obtained if, according to claim 8, the approaches are parts of an elongating bearing eye for the actuator. This means that the bearing stubs of the housing can come into contact with parts of the inner surface of the lugs, thus increasing the bearing surface. This also achieves additional tolerance compensation.
- the components to be locked are in principle provided with bevels which lead to the desired spreading effect. After reaching the spread position, the parts to be connected to each other are locked together using corresponding undercuts. The run-up bevels are placed in such a way that the surfaces to be locked together are bent out of their original position in the direction of assembly until after reaching their end position they can spring back while accommodating the corresponding bearing body.
- the use of the combination of features according to claim 10 is recommended. Thereafter, the force required for the assembly between the actuator and the housing is reduced in that the side surfaces of the actuator are enlarged by means of webs Elasticity are provided so that breaking of the operator when snapping onto the housing is largely excluded.
- the combination of features according to claim 11 is recommended, according to which the actuator is simultaneously used as a reflector for lamps protruding from the switches to be actuated. It is advisable to manufacture the actuator preferably from light-colored plastic, in particular by an injection molding process.
- Fig. 2 is a top view of the switch arrangement of FIG. 1 shown somewhat reduced and
- FIG. 3 shows a section approximately along the line A, B, C, D, E, F in FIG. 2.
- the circuit arrangement according to FIG. 1 has two switches 1, 2 and possibly a third switch 3 which are mounted on a base plate 4 and are electrically connected.
- the base plate 4 sits on a connection plate 5 which carries a plug 6 with connection contacts 7 which are anchored in the connection plate 5 and protrude through the base plate 4 and are connected there with electrical lines. These lines then lead in a suitable manner to the individual contacts of the switches 1, 2 or 3.
- a housing 8 is placed on the connection plate 5 and releasably connected to it.
- the base plate 4 is also detachably connected to the connection plate 5 by means of a screw connection.
- a housing 8 provided with switches is thus obtained, which can be snapped into place in a receptacle not shown in FIG. 1 by means of locking lugs 9.
- an aperture 11 (FIG. 2) is held by the receptacle, which has an aperture opening that is shown in FIG. 2 from above seen, covering parts of the switch.
- actuating sleeves 12, 13 which have to be depressed in order to actuate the switches 1, 2.
- Luminous elements 14, 15 protrude from the center of the actuating sleeves, which are intended to facilitate the search for the switch and the recognition of the function currently being used.
- the switch arrangement is further provided with an actuator 16, which is pivotably mounted at point G relative to the housing and also serves to be able to act on the actuating sleeves 12, 13, which is done with the aid of the bottom surfaces of the actuator 16 belonging reflectors 18, 19 happens.
- the reflectors 18, 19 have openings through which the luminous bodies 14, 15 protrude and provide for the illumination of the bottom surface 20 of an actuating cap 21.
- the actuating cap 21 acts on the actuator 16 via transverse webs 22, 23 by engaging these transverse webs on the end face of the reflectors 18, 19 in FIG. 1, which extend perpendicular to the viewer plane.
- the central region 24 of the actuating cap 16 is supported on a lattice-shaped section of the actuator 16.
- the actuator 16 has at the level of the longitudinal axis K penetrating the point G in FIG. 1 perpendicular to the viewer plane, two bearing openings 29, 30 aligned with one another, into which corresponding stub axles 32, 33 of the housing are engaged.
- the stub axles have ramp slopes 34, 35 to which corresponding slopes 38, 39 of the actuator 16 are assigned.
- Half-shell-shaped bearing shells 36, 37 extend outward from the bearing openings 29, 30 and have essentially the shape of a half circular ring in section. These half-shells protrude through corresponding openings in the cap 21.
- the lugs 36, 37 forming the bearing shells penetrate corresponding arcuate sections 38, 39 in the cap 21, these being sections of a circular arc, preferably a semi-circular one , Bow deals.
- actuating cap 21 In the center of the semicircular arc, two hemispherical projections 40, 41 are provided which protrude from the actuating cap 21.
- the actuating cap which floats in the direction of the bearing axis K via the shoulders 36, 37 of the actuator 16, is supported with the projections 40, 41 on the inner surfaces 42, 43 of the opening which surrounds the actuating cap 21. Thereafter, regardless of the position of the housing 8 relative to the diaphragm 11, the actuating cap 21 is always axially symmetrical with respect to the inner surfaces 42, 43.
- Fig. 3 shows the actuating cap 21 in a position shifted to the right relative to the plane of symmetry of the switch 8.
