The invention relates to a combined electrical device switch according to the preamble of claim 1.

From GB-PS 14 38 372 a combined electrical device switch is known, the button of which both can be rotated as well as moved. The sliding or turning movement of the switch button is mechanically transferred to contact springs. Such a switch is suitable - as also shown in the GB-PS - for switching several switching levels, e.g. 3. an electrical device and for switching it on and off.

As a rule, however, electrical devices do not only have an on / off switch that, under certain circumstances, such as can also be designed multi-stage in the aforementioned prior art, but an additional voltage selector switch. Voltage selector switch and on and off switch are usually separate and spatially spaced apart. This requires extensive line routing and contacts; In the case of the devices, which are often very compact, this makes assembly and repairs more difficult.

The object of the invention is to develop a switch according to the preamble of claim 1 so that that two switching operations can be carried out completely independently of each other and the switch can be made compact.

This object is achieved by the features specified in the characterizing part of claim 1.

Advantageous further developments of the subject matter of the invention are specified in the subclaims.

This arrangement is particularly suitable for devices that can be applied to different voltages. For the switch from one voltage to the other, which occurs relatively seldom, becomes the rotary organ used, so that this is to be operated only relatively rarely.

The invention is described below with reference to the exemplary embodiments shown schematically in the drawing explained in more detail; it shows

F i g. 1 the essential part of the switch housing with switching element in the off position;

F i g. 2 the same switch in the on position;

F i g. 3 the rotary switch;

F i g. 4 the circuit arrangement;

F i g. 5 another version.

In the housing of an electrical device, which is also the switch housing 1, a switching element 2 can be moved linearly arranged; the handle part 20 protruding from the housing 1 enables the switching element to be actuated 2 in the usual way; the housing slot 10 is correspondingly large.

The switching element 2 has a sliding part 21 which is bent downwards and contacts 3 carries, which serve to close the mains current and the mains current-carrying contacts 30, 31 are opposite.

In the handle part 20 a rotatable additional switching element 4 is mounted, the contact closure with the contact plate 22 has; this contact plate 22 is connected to the switching member 2, so that the rotatable additional switching element 4 and the contact plate 22 take part in all sliding movements of the switching element 2.

The power cable connection 5 is hinged to the housing 1 in a rotatable manner in a form not shown in detail. The cable ends are guided on sliding contacts that are in constant contact with contacts 30 and 31. Of the Contact 30 is arranged centrally and designed as a button, contact 31 as a ring.

The two resistors η ί and R 2 in the circuit according to F i g. 4 symbolize the switchability of the device from 120 and 220 V, the contact 3 the on and off switch and the number 6 the connection for the rotatable additional switching element 4. In the outer head of which a slot 40 is provided for operation with a coin.

Characterized in that the rotatable additional switching element 4 on the contact plate 22 of the switching element 2 is arranged, its contacts and mating contacts 41 with each linear movement of the switching element taken away.

Ir. F i g. 5 shows another exemplary embodiment. Mains current is applied to the spring contacts 50 in the housing 11 of an electrical device via the mains cable 51 fed in. The device switch in turn has a movable part 52 and a rotatable part Part 53 on. As already described above, the rotatable part 53 is mounted on the sliding part 52. The switch is longitudinally displaceable via the handle part 54. The longitudinal displacement takes place Contact closure between the sliding contacts 55 and the resilient contacts 50. By turning the rotatable part 53 there is a voltage division (circuit diagram approximately corresponding to FIG. 4),
