DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(9) FIG. 1 shows a holding device in accordance with the invention in combination with a crossbar switch as actuator. The holding device in accordance with the invention substantially has a cuboidal basic body with a first housing portion 1 that has a preferably concentric recess 2 for receiving an actuator 3 of a command and alert device, and with a second housing portion 4 that is arranged on the first housing portion 1, preferably in a manner lying there against, and which continues the recess 2 of the first housing portion 1 and which has guide rails 5 for guiding transmission elements 6, where the transmission elements 6 serve to transmit an actuation of an actuator 3 to a switching element. The first and second housing portions 1, 4 may be formed in one part. However, they may also be formed in two parts, and therefore the second housing portion 4 is fastened to the first housing portion 1, for example, via a detent or a screw connection or a clamping connection. A clamping ring is preferably arranged between the two housing portions 1, 4, where the clamping ring is operable via a lever that fixedly secures the actuator 3 in the recess 2 of the holding device. The actuator 3 can also be released again via the lever in order, for example, to exchange the actuator. Housing contours formed as projections or recesses that predetermine the correct position of the actuator 3 upon insertion into the recess 2 are arranged in the recess 2 of the holding device.

(10) At least four switching elements can be fastened to the holding device in accordance with the invention. Here, the switching elements can be of structurally identical configuration, i.e., standard switching elements can be used. No special switching elements have to be manufactured. Two of the switching elements can be activated via the transmission elements 6 arranged in the holding device. The other switching elements are activated directly via the actuator 3.

(11) The transmission elements 6 are preferably L-shaped with two limbs 7, 8 that are preferably at an angle of 90 to each other. Here, one limb 7 of the transmission element 6 is arranged in a guide rail 5 of the second housing portion 4. The other limb 8 of the transmission element 6 has a preferably U-shaped portion 9 with two limbs 10, 11 and a transition region 12 that is connected to the first limb 7 of the transmission element 6 via a connecting web 13.

(12) The actuator 3 in FIG. 1 is a crossbar switch. The actuator 3 preferably has a cylindrical basic body that is inserted into the recess 2 of the holding device. At least four rams are preferably arranged in the cylindrical body, via which rams the switching elements on the holding device can be activated directly or indirectly via the transmission elements 6 of the holding device. The actuator 3 has an activation mechanism which is realized via the joystick 14 and which individually activates the rams.

(13) FIG. 2 illustrates a further exemplary embodiment of the combination of actuator 3 and holding device in accordance with the invention for the switching elements. In this exemplary embodiment, the actuator 3 is a selector switch that is operated by rotation. The transmission elements 6 in the holding device in accordance with the invention are arranged in parallel and lying opposite one another. The outer switching elements, which are each located on the edge of the housing outer sides of the holding device, are activated via the transmission elements 6.

(14) FIG. 3 shows a detail of the holding device in accordance with the invention with transmission elements 6. The transmission element 6 has a receptacle 15 on the first limb 7 for a spring element, preferably a compression spring. The receptacle 15 is preferably formed as a blind-hole-like housing contour with a centrally arranged guide dome 16. The mechanism of the holding device in accordance with the invention makes provision for the limbs 10, 11 of the U-shaped portion 9 to be acted upon, in the event of actuation, by the limbs 17 of the ram 18 of the actuator 3. A contact point 19 therefore arises between the transmission element 6 of the holding device and the ram 18 of the actuator 3. That surface of the U-shaped portion 9 of the transmission element 6 that lies opposite the contact point 19 serves as a contact surface 20 with respect to the switching element. A spring element 21, via which the ram 18 is reset, is arranged between the limbs 17 of the ram 18 of the actuator. In addition, four slots 23 for switching elements are preferably arranged on a longitudinal side 22 of the second housing portion 4, where the slots are characterized by positioning aids 24 in the form of housing projections and by recesses 25 in the longitudinal side 22 of the second housing portion 4.

(15) FIG. 4 shows the first housing portion 1 of the holding device in accordance with the invention with a transmission element 6 that is separate and is inserted. The transmission element 6 has the receptacle 15 on the first limb 7 for a spring element 26, preferably a compression spring. The receptacle 15 is preferably formed as a blind-hole-like housing contour with a centrally arranged guide dome 16. The spring element 26 can be inserted into the blind-hole-like housing contour via the guide dome 16. The spring element 26, serves for resetting the actuator 3. The transmission element 6 is inserted, together with the spring element 26, into the guide rail 5 of the first housing portion 1. Latching lugs 28, via which the second housing portion 4 can be secured on the first housing portion 1, are arranged on a side wall 27 of the first housing portion 1.

(16) FIG. 5 illustrates the second housing portion 4 of the holding device in accordance with the invention. Housing projections 30 with recesses 31, which are configured to receive the latching lugs 28, are arranged on a side wall 29 of the second housing portion 4. This construction of housing projection 30 and recess 31 is also situated on the side wall 32 running parallel to the side wall 29. FIG. 5 shows the continuation of the recess 2 in the second housing portion 4. The slots 23 for the switching elements are arranged on the side wall 33 connecting the side walls 29 and 32. The guide rail 5 of the first housing portion 1 is continued in the second housing portion 4, where the first housing portion 1 forms the end stop for the transmission element 6 in the unactuated state.

(17) FIG. 6 shows the lower side of the second housing portion 4 of the holding device in accordance with the invention with the four slots 23 for the switching elements, and with a receiving bore 34 for the spring element 26.

(18) FIG. 7 illustrates an exemplary embodiment of an actuator 3, preferably a selector switch. The actuator 3 preferably has a cylindrical basic body 35. Housing contours 36 in the form of projections and recesses, which are configured to precisely fit the housing contours in the recess 2 of the holding device, are arranged on the outer side of the cylindrical basic body 35. Preferably at least four rams 18 are arranged in the cylindrical basic body 35, via which rams the switching elements on the holding device can be activated. The actuator 3 has an activation mechanism that individually activates the rams 18. The rams 18 in the actuator 3 are either preferably U-shaped or L-shaped. The rams 18 that are U-shaped and the rams 18 that are L-shaped are arranged lying opposite each other in parallel in the cylindrical recess of the basic body of the actuator 3. When the U-shaped rams are actuated, two limbs 17 protrude out of the cylindrical basic body of the actuator 3. In the event of actuation, where the U-shaped limbs 17 of the ram 18 of the actuator 3 strike against the limbs 10, 11, which are U-shaped, of the transmission element 6 of the holding device. The rams 18 of the actuator 3, which are L-shaped, strike directly against the switching elements with the surface or with the limb 37 that is oriented into the interior of the cylindrical basic body of the actuator 3, where the limbs 37, 38 are at an angle of approx. 90 to each other. The other limb 38 of the L-shaped ram 18 of the actuator 3 is positioned in guide pockets 39 on the housing edge of the cylindrical basic body of the actuator 3.

(19) The holding device in accordance with the invention is distinguished by transmission elements in the holding device, where the transmission elements transmit the ram movements of the actuator to the outer switching elements. In addition, the holding device is formed with at least four direct receptacles for switching elements. The holding device in accordance with the invention permits the use of structurally identical standard switching elements.
