• the invention relates to an electrical (on) isch or control device in a narrow design, in particular timer, with on the circumference of a rotationally symmetrical carrier with associated pivot bearing and optionally arranged on the circumference adjustable, but otherwise captive and when driven by a clockwork-driven shaft and scanning electrical (electronic) circuit device to be actuated in the output circuit for the current consumer and related systems,
• a clockwork-driven shaft and scanning electrical (electronic) circuit device to be actuated in the output circuit for the current consumer and related systems
• With a lower part and an upper part containing housing with flat cuboid elements and with built-in drive device, switching device, output circuit with terminals and program carrier according to the preamble of claim 1.
• the invention relates to a housing of the type described above, the lower part and the upper part lying opposite one another in the form of flat shells, of which at least one of the two is equipped with molded side walls and can be positively combined by plugging in a complete housing.
• the switching elements are used functionally in the industry-standard combination with other modules and their number is equal to the number of selectable time stages for a periodic switching program corresponding to the circulation of the program carrier.
• latching means and stops are installed in a manner known per se in accordance with the displacement positions of the switching elements necessary for the operating states of the switch to be brought about.
• the design has also been determined by the desired application and the installation requirements, for example. with visible time display for the entire time program in front view or only part of it with a side view of part of the time program. These aspects are particularly dependent on detailed questions regarding the construction of the housing and the installation of the individual assemblies.
• the present invention is therefore based on the object, the constructive design of the means for triggering switching operations in control technology based on the above-mentioned modernization of staircase time switches also for timers or similar switching or control devices to improve the space requirements of the assemblies and components by appropriately redesigning, reorganizing and summarizing them by packing the adjustable or selectable switching elements even more densely, with additional quality requirements during production being met by simplifying the manufacturing process.
• the space requirement should continue to be reduced noticeably despite the increase in the number of time stages of the switching program, with the greatest possible precision having to be ensured.
• the manufacturing tolerances and fit air gaps should not be set below a certain minimum, so that the technical producibility is ensured and the production can be carried out economically.

• the program carrier sub-group 20 which is visible in fragments, is on the double pipe partial shell 4 as a pipe bearing comm combination rotatably supported, which part of this pivot bearing contains a semicircular piece with the end pieces 7, 8 of the pipe shell section and is supplemented by the abutment pin pin 9 as a counter bearing so that the annular program carrier group is fully supported.
• the double-pipe partial shell 4 has at one point in the exemplary embodiment in the middle between the ends of the tubular-shell section a tubular guide bush 10 formed in the inner wall 52 of the double-pipe partial shell for centering the counter shell by means of a half-shell 29 receiving the tubular guide bush 10 (in Fig. 4), which is formed on the base plate of the upper part 195, also not visible.
• the switching elements 12 and the guide grooves 13 of the molded bodies 14 for axial displacement of the switching elements 12 are visible in the left part 11 , while in the right part between the segment-like cutouts, for example. 1, the switching elements 15 and the guide grooves 16 of the shaped bodies 17 for radial displacement of the switching elements 15 are visible.
• the empty surface 18 of the base plate 5 without any formations, which extends to the opposite end piece 7 with the interposition of the abutment pin 9.
• the program carrier group 19 has a toothed ring on the outer edge 21, over which it extends the drive group 22 is driven via the end pinion 23.
• the scope of the program carrier is scanned by the projections of the switching elements 12 and 15 by means of the switching lever 25 which can be pivoted about the axis 24 and via a contact intermediate lever 26, not shown here, to which likewise not shown switch block transmitted.
• the double-pipe partial shell with the sliding surfaces 51, the outer low support 52 and the high inner bearing surface 53 can be seen in section and, together with other formations (pins, bushings, etc.), are molded onto the base plate 5 of the lower part 6.
• 1c shows two configurations of the program carrier, of which the one (left) for axial displacement of the switching elements 12 is guided in the molded body 62 and the adapter 63, and the ring gear 64, and optionally the other configuration of the program carrier for radial displacement of the switching element 15 can be used in the molded body 66 with the fitting 67.
• One of these program carrier sub-groups 20 of your choice can be plugged onto the double-tube partial shell 4, as a result of which the ring gear 64 is brought into engagement with the end pinion 23.
• the program carrier subgroup 20 (same as the example from FIG. 1c on the left) is shown with the time scale 68 visible from the outside, the switching elements 12 and the ring gear 64.

• the flap cover (not shown here, is mounted in the bearing bush 28 (FIG. 1a).
• the drive group 22 contains, in addition to the gear parts mentioned, a stacking gear 141 consisting of a plurality of gearwheels which, together with the stator and coil 143, form a group as a compact, completely assembly unit.
• the switching lever is pivoted about the axis of the pivot bearing 108 by the protruding heads of the switching elements, the opposite end 107 actuates the movable contact 112 of the switch group 110 of the switch block 111 via the intermediate lever 133.
• the program carrier with bearing 19 is therefore a module and with the functionally following module switch block 111 coupled via the shift lever 25 and the intermediate lever 133.
• the switch block 111 is combined with the contact set 112, 113 and the two terminals 114, 115 to form an independent module.
• the switch block 111 can also be set from time switch mode to "permanent ON” and possibly “permanent OFF” from the outside, the Shift lever 25 is continuously lifted from the switching elements and the switch group 110 is blocked either in the "closed” or "open” position.
• the switch group 110 is, in principle, a so-called snap switch, whereby due to the interaction of the intermediate lever 133 and the spring 132, the movable jumpable contact lever 112 snaps during the transition from one operating position "open” to the other "closed", as can be seen in FIG. 5 recognizes where the contacts 112, 113 are closed because the contact lever 112 has snapped over the axis of the spring 132.
• the intermediate lever 133 has then been moved from the rest position to the bearing point 134 of the spring 132 by the opposite end 107 of the shift lever 25 as a result of the cam 106 of the shift lever 25 lifting off or by actuating the manual shift lever 131.

• this contains a voltage divider to reduce the mains voltage to the operating voltage of drive group 22.
• an accumulator 172 is located on this circuit board 171 - taking advantage of the other parts or modules not required area - as an energy store for the power reserve in the absence or failure of the mains voltage, an electronic generator is installed as a "time base" 174, namely as an independent sub-assembly containing quartz crystal, rectifier, clock IC and capacitor.
