Definitions

• the invention relates to a navigation switch with an actuating element which can be tilted at least in two directions, and by means of which the navigation switch can be operated, a housing accommodating the actuating element and a switching element on which the actuating element acts.
• Navigation switches generally have a switch housing with a switching element arranged in the interior of the switch housing, which can be moved against at least two contact areas and, when moved, comes into a contact position that switches an electrical contact.
• Switching element has an actuating arm which is guided outwards as an axial extension of a switching lever arranged in the interior of the housing.
• the actuating arm can be pivoted from a central rest position in several directions via an operating element which is located in a switch housing.
• Such navigation switches are known for a variety of applications. They are generally used to control electronic consumer electronics devices, such as. B. in digital cameras, VCRs or cell phones but also for menu control in electronic
• Data processing equipment used are used to reduce the number of components if several functions are assigned to individual components.
• the actuating element has one on its underside Tappet so that the actuating arm of the switching element can be mechanically contacted.
• the plunger of the actuating element transmits the actuating force to the actuating arm of the switching element, so that it reaches a contact position and switches an electrical contact.
• the object of the invention is to provide a navigation switch in which the switching element is better protected against premature wear and destruction.
• a limiting element is arranged between the actuating element and the housing, which limits the actuating forces to the switching element.
• This navigation switch has the advantage that by using a limiting element between the actuating element and the housing receiving the actuating element, any type of switching element can be protected against improper or excessive actuation.
• Actuating forces that are too great are introduced via the limiting element into the side walls of the housing receiving the limiting element.
• a safe guiding of the plunger of the actuating element on the actuating arm of the switching element is made possible.
• delimiting element is formed in one piece with the housing and that the delimiting element and the housing are made from an elastomeric plastic.
• an advantageous embodiment provides that the limiting element is convex to the actuating element and has a lattice-like structure.
• the limiting element can also be designed as a curved disc made of plastic or metal.
• the limiting element has an axial recess for receiving a plunger located on the underside of the actuating element.
• a preferred embodiment of the invention provides that the housing receiving the delimiting element encloses a circular cavity, with at least two notches in the outer region of the bottom delimiting the cavity are formed and that the convex limiting element has at least two further counter catches which engage in the correspondingly provided catches of the housing.
• the limiting element is inserted into the cavity of the housing, the limiting element being rotated clockwise by 45 degrees after the assembly, so that the counter-catches of the limiting element engage in the catches of the housing.
• the invention makes it possible to create a navigation switch with very little production and assembly effort, in which wear that occurs under normal circumstances due to excessive actuation forces is prevented by means of a limiting element.
• the structural unit of the housing for receiving the actuating element can be stored and handled in a preassembled form without having to use any special care.
• actuation forces occurring on the actuating element are introduced into the side walls of the housing via the additional limiting element.
• limiting elements microswitches can also be protected against improper or excessive actuation.
• the limiting element enables the actuating element to be guided in tracks to prevent undefined tilting.
• the use of the optional limiting element enables the properties to be adjusted regardless of the material of the housing.
• the lifespan of the Navigation switch or the switching element is positively influenced.
