• the present invention relates to a housing having an at least one actuator disposed therein, such as a housing.
• a potentiometer, a switch, an adjusting eccentric, an adjusting screw or the like having assembly and an actuating element for actuating the at least one actuator.
• potentiometers ie adjustable resistors, switches or the like are used for adjustment purposes, these actuators are usually soldered to a so-called circuit board.
• circuit board For actuation of the actuators actuators are used, by means of which a change in the adjustment positions can be brought about.
• actuators which have a simple and inexpensive construction and which are subsequently equipped with an actuator.
• actuators There are also known purely mechanical actuators such as adjusting eccentric, adjusting screws or the like. Such actuators can also be present in embodiments in which overloading can lead to damage.

• Actuator itself and an outer wall of the housing and can be operated only by a cutout in the housing wall by means of a suitable tool.
• a further development of the invention provides that in the surrounding region of the cutout, detents arranged on the inner side of the outer wall are provided, into which latching projections attached to the actuating element engage.
• a latching adjustment of the actuator can be made by a simple manner, wherein the number of latching steps the corresponding design of the respective surrounding area of the cutout and / or by attaching a more or less large number of locking projections on

• Figure 7 is a perspective view of the control element.
• the reference numeral 1 denotes in each case a housing in which, as is apparent from FIG. 5, an assembly 2 with at least one actuator 3 shown only schematically is arranged.
• the assembly 2 consists of the aforementioned at least one actuator 3 and, for example, a circuit board. 4
• the actuator 3 is a potentiometer, which is adjustable by rotation of an actuating element 5.
• the actuator 3 is arranged adjacent to an outer wall 6 of the housing 1.
• the actuating element 5 is equipped with an actuating shaft 7 with driving function and engages in the actuating member 3 a.
• the actuating axis 7 passes through a through hole 8 of the printed circuit board 4.
• the actuating element 5 is equipped with a shim 10. This shim 10 abuts against the inside of the outer wall 6 or at the bottom of a recess 11 within the outer wall 6 and is supported radially in the edge region of this recess 11, so that in this area attacking radial forces can be intercepted.
• the distance between the circuit board 4 and the contact surface of the shim 10 on the outer wall 6 is chosen so that between the shim 10 and the outer wall 6 results in a certain bias.
• the bottom of the recess 11 is peripherally equipped with detents 12.
• the actuating element 5 is provided on its outer wall 6 facing end side of the dial 10 with locking projections 13 which engage depending on the rotational position of the actuating element 5 in the notches 12 of the outer wall 6.
• the outer wall 6 is provided with a sector-like cutout 14 in the illustrated embodiment.
• the shim 10 is provided with a receptacle 15 for an unillustrated actuating tool, said receptacle 15 is in the region of the cutout 14 of the outer wall 6. This is very clearly evident in particular from FIG.
• the shim 10 and / or the surrounding area of the cutout 14 of the outer wall 6 are spring-capable in the direction of the actuating axis 7 of the actuating element 6.
• both the housing 1 as well as the entire actuator 5 are made of a suitable plastic with corresponding spring properties. Since the shim 10, as already mentioned above, with a certain bias voltage applied to the surrounding area of the cutout 14 within the outer wall 6, the locking projections 13 are achieved by the spring bias to achieve a
• An actuation of the dial 10 is effected by inserting an actuating tool, for example a screwdriver, into the receptacle 15 and then rotating the dial 10 about the center of the actuating axis

• the actuating tool passes through the outer wall 6 of the housing 1 in the region of the cutout 14, so that a rotation of the shim 10 is only so far possible until the actuating tool abuts the respective end boundary edges of the cutout 14. Even if this takes place with a comparatively high expenditure of force, the actual actuator 3 is thereby not acted upon mechanically, and ultimately the same applies to any applied axial forces, since these are predominantly intercepted by the collar 9 of the actuating element 5 resting on the printed circuit board 4.
• step-like intermediate positions can be adjusted during adjustment, which can be made visually clear by applied on the outside of the outer wall 6 markers 16.
• a displaceable actuating element 5 instead of a rotatable actuating element 5, in particular if hereby a switch is to be actuated as an actuator 3.
• the actuating element 5 can be provided with a receptacle into which a tool is introduced, by means of which a tool is inserted. Shifting of the actuating element 5 within a cutout 14 in the outer wall 6 is possible. Also in this solution, the actuating tool would rest at the end of the displacement path at the end edges of the cutout 14, so that here too overloading of the actuator 3 can be prevented even.
• the actuating element 5, here in particular its section located in the region of the cutout 14, can be illuminated by a light-emitting diode viewed from the inside of the housing 1, so that either the recess 15 in the actuating element 5 or the entire region of the cutout 14 in the outer wall 6 visually recognizable.
• any other suitable bulbs can be used.
• the printed circuit board 4 and the at least one actuator 3 can be used to advantage for controlling the electric drive of a drawer or a comparable furniture part.
• the invention offers the advantage that actuators can be used which are manufactured relatively inexpensively and without special regard to mechanical stability, since a mechanical damage of the actuators is practically avoided by the described construction.
