AC switch

The invention relates to an alternating current scarf Ur "Ht at least a contact rocker which can be pivoted about a central bearing support and which is an actuating rocker is zugeorftdnet with pressure element »In the known switches of this type, the contact rocker and the Operating rocker pivotable about parallel axes

and form one end or both ends of the contact rocker with fixed contact points lifting contacts »Such switches are for a wide variety of switching tasks Suitable you can both as a simple off switch or as a change, series and. multipole switch be executed, in particular it is possible to design the switches as cross switches * or for To set up special tasks, which require an exchange of current paths within the switch do·

The invention is to enable the target for Sohalter of the aforementioned type, a particularly low design "by the invention recommends that the actuating rocker has a relation to the contact system open cavity ^ and that the contact rocker is arranged so that it lies substantially within said cavity “The close proximity of the rocker switch and the rocker switch can be used to design both rockers * and to arrange them mutually in such a way that the rocker switch forces the contact rocker to switch over if the rocker switch does

"1-2'—

in a switching position by gluing or the like Circumstances are recorded so that the pressure exerted by the pressure element of the rocker switch is insufficient, to bring about a pivoting of the contact rocker in the desired sense.

The relocation of the contact rocker in the hollow rocker switch can be used in a further embodiment of the Invention design particularly largely that the pivot axis of the rocker switch is less Distance from the base is attached as the pivot axis of the contact rocker «

It has proven to be useful to equip the rocker switch on both long sides with protruding bearing pins lying outside the contact rocker, which rest in the corresponding bearing points of the base wherein the actuating rocker is defined by a bearing body covering and practical the pot-closing shell "the upper part can in the 'rule ψ consist of a simple plate which comprises a cutout for the actuating rocker, the cup shape of the base allows the attachment of the terminals of the solid Contact points in the sideways area of the base area in such a way that the connection contacts can be operated from the face of the base ©

The parts of the switch according to the invention can so closely together in the axial direction that the contact system and the actuation system load-bearing plinths can be set in the plaster layer of a wall or even on top of the plaster layer without a to bring about a further projection from the wall surface. It is possible to use the base into a convex and with a passage opening cover plate provided for the rocker switch

fit, their contact surface on the wall "with plaster arrangement of the switch has a maximum distance corresponding to the plaster layer from the base floor On the other hand, surface-mounted arrangement is the same as the base floor Escape lies »-» The fully assembled © switch makes a difference with regard to the projection from the wall surface only insignificantly from a switch with a rocker switch, its base in a flush-mounted box * is set "

The object of the invention is illustrated in the drawing in one embodiment; in the Drawing shows:

3 shows a vertical line section i of Fig. 4j

Fig, 4 is a plan view of the base of the Switch;

The switch shown consists of a base 1, which can be attached to a wall surface at 2, and a cover plate 3 »which also rests on the wall surface and by means of screws 4 on the Base 1 is attached «

The base 1 consists of the base part 5 and a plate-shaped upper part 6, which by means of hollow rivets 7 are firmly connected to each other, at the same time the The fastening screws 4 of the cover plate 3 serve as nuts «

The base part 5 is designed as a pot in which two lateral contacts 8 and a middle Contact 9 are set. Each of these permanent contacts

a connection contact 10 or «11 is assigned, which • ι »recesses of the base pot 5 let in and in The terminal contacts are accessible in the transverse direction 10 and 11 associated clamping screws can be operated from the front of the base «For this purpose If the upper base part 6 is provided with corresponding cutouts, the upper base part 6 also contains a Cutout 12, which adjoins a corresponding cutout 13 in the cover plate 3 »The Cutouts 12 and 13 form the passage opening for the rocker switch 14 of the switch, which the Pivoting of the contact rocker 15 resting on the middle contact position © 9 causes.

The contact rocker 15 is in a conductive connection with the connection contact 11 via the contact 9, which serves as a support support, and forms lift-off contact points with the fixed contacts 8. The actuation of the contact rocker 15 is normally effected by the ball 16, which is resiliently supported in the actuation rocker and which moves with each pivoting of the actuation rocker 14 to the opposite side of the bearing support 9 and thereby carries the contact _{rocker 15 with it 0} The actuation rocker 14 is hollow and so close to the contact rocker 15 '? moved so that the latter lies in the cavity of the rocker switch »

If the contact rocker 15 at one of the contact points should stick by fusing, and the pressure exerted by the ball 16 to release the contact rocker is not sufficient, the rocker switch 14 will force the release of the rocker contact 15 because the rocker contact 15 protrudes into the pivoting path of the rocker switch.

The actuating rocker is provided with two projecting into the socket bearing cutting 17, located on either side of the contact rocker 15 and protrude from the flanks of the rocker switch 14 'makes it possible, ¹ actuating rocker 14 to define the H by means of the Soekeloberteils 6 in the bearings 18 of the lower base part 5 »The bearing points 18 limit the pivoting path of the rocker 14 at the same time.
