The solution is that the actuating lever can be inserted into the holding indentations by the free ends of the bearing tongues S, without initially having to do something about the counterclockwise twisted position of the position compared to the one shown inserted lever can be exchanged from above into the recess "em" without further use of the operating lever. It is therefore 5 out and then the operating lever is simply possible to turn the switch together with a selection clockwise. The movement is to be offered by actuating levers for the most varied of applications through the penetration of the bearing tongues in cue dusfalls and to provide it to the customer the wedge surfaces 10 and werzusetz'en. 10 den bent outwards.

The actual bearing tongues 5 are executed worth η, which extensions are movable between the abutment surfaces when the extensions 6 are spread through the wedge-shaped surfaces of the indentations and thus do not significantly deform the cams 9, each limiting pivoting movement. It is thus possible, if not to the extent that the safe ^{steering mechanism could jeopardize the insertion movement} on other sides of the switch housing, using stopping means Swiveling in the fold.

Different actuating levers with the same or similar bearing points can be pivoted get connected. The bearings can be designed differently, only the condition to meet is that the bearing tongues initially without deformation and then clearly steered in the storage depressions can be introduced. In the case of the in FIG. 1 to 3 illustrated embodiment can be perceived as a disadvantage that the free ends of the bearing tongues are slightly above the level of the left the narrow side of the switch housing shown protrude. However, this can be done through appropriate dimensioning and / or arrangement of the bearing point can be avoided without further ado.

If limit stops for the pivoting movement of the operating lever are not required, so can the stops 6, 8; 14, 15 are omitted, whereby an insertion of the operating lever without any ίο elastic deformation of parts of the bearing tongues is possible.

The microswitch on the two opposite sides does not allow the actuation lever to be placed on lying flat sides of the switch housing 5 very easily. It takes some skill to formed bearing points for an operating lever, the bearing tongues so on the wedge-shaped bearing journals characterized in that each postpone that the journals into the holes The bearing point collapses in a manner known per se as a recess of the bearing tongues. It is also a fine (7, 15) is formed, which requires up to at least a strong deformation of the bearing tongues Narrow side (2) of the switch housing (1) io borrowed.
