1 2 Such a design is relatively easy to patent claims: agile and prone to failure due to the large number of interacting elements. 1. Time switch with bimetal drive for car task of the invention is therefore the effort matic bread toaster, in which one by means of 5 and at the same time the susceptibility to failure one after this of an operating element in a latching position principle working timer for a bread toaster pressed the switch plunger to reduce the heating of the bimetal. In particular, a simple entry and the roasting heating is switched on so that the roasting time can be set, characterized in that the fixed one without affecting the bimetal tensioned bimetal (8) on the switch plunger (9) would have to be io. Acts via an intermediate member (13), the Ab- According to the invention, this task is in a can be adjusted by the switch plunger (9). Time switch of the type described above thereby 2. Time switch according to claim 1, characterized in that the firmly clamped bimetal on the indicates that a switch plunger attached to the bimetal (8) acts via an intermediate member whose Pin (27) in an elongated hole (27 ') of the inclined, 15 distance from the switch plunger is adjustable. This leaves d.

H. at an angle to the longitudinal 3. Time switch according to claim 2, characterized in expansion of the elongated hole adjustable intermediate, that the adjustment is performed by a member. The adjustment can through second operating member (14) can be brought about. a second operating organ can be effected. 4. Time switch according to claim 3, characterized in accordance with a further embodiment of the invention indicates that both controls are around both controls to a common a common axis (50) rotatably arranged axis rotatably arranged, for. B. in such a way that are. 25 the operating elements made of flat, one on top of the other 5. Time switch according to claim 4, characterized in that the operating elements (14, 15) are made of levers which are rotatable about a common central pin. The second control element can be made of flat superimposed structures, which advantageously move around one over a scale,
common means serving as an axis (50). An embodiment according to the invention will consist of bolt rotatable levers. 30 explained below with reference to the drawing, 6. Time switch according to one of claims 3 which, in a perspective view, shows the time to 5, characterized in that the second switch of an automatic bread toaster shows.
The operating element (14) is located above a scale in the time switch shown in the drawing. ter an operating member 15 is provided which 35 actuated the electrical switch 1 via the switch plunger 9. At the bimetal 8, whose heating via the Switch 1 takes place, the pin 27 is attached, which is in the Elongated hole 27 'of the intermediate member 13 is guided. With the help of the second one for setting the roasting time The invention relates to a time switch with a bi-40 (roasting duration) operating element 14 is a metal drive for automatic bread toasters, in which the intermediate member 13 is inclined, that is, under a wind through a switch plunger which is pressed into a kel against the longitudinal rotation of the elongated hole 27 'latching position by means of an operating element the heating of the adjustable so that the bent end 23 of the Zwi-bimetal and the roasting heating are switched on. between member 13 a larger or smaller Ab-In the USA.-Patent 2 367 044 is an elek- 45 from the switch plunger 9 is received.
