Definitions
- the invention relates to an electrical switch with an actuating element slidably mounted in a housing with an extension which extends through a housing wall with the interposition of a seal.
- Such a switch is known from practice.
- the housing wall as a seal is assigned two opposing sealing lips, between which the shoulder is arranged.
- the sealing lips are tangent to the neck of the actuating element and come into mutual contact in the further course, openings in the sliding directions of the actuating element being present directly at the neck between the sealing lips, the size of which essentially depends on the geometry of the neck and the elasticity of the material of the sealing lips is determined. Water can enter the interior of the switch through these openings.
- Sealed rocker and push-button switches are also known, the actuating elements of which are spanned by an elastic cap connected to the housing.
- an elastic cap connected to the housing.
- such a cap affects tactile perception. ability of the switching operations and is often undesirable from a design point of view.
- the object is achieved in that the seal is designed as a sealing membrane made of an elastomeric plastic, which bears sealingly against the attachment under pretension.
- the prestressed contact of the sealing membrane fixed to the housing wall against the attachment effectively prevents dirt or water from penetrating into the interior of the housing in the region of the actuating element.
- the seal has no effect on the actuating element, which can thus be designed freely in its shape and can be designed such that it covers the seal, after which it is no longer visible to a user of the switch.
- the housing can be connected to a base in a sealed manner with the interposition of an O-ring seal.
- the sealed mounting of the actuating element is particularly necessary when the switch is used as a seat adjustment switch in a motor vehicle, which is installed in a side panel of a motor vehicle seat, since this side panel is often not spanned by a roof of the motor vehicle and splashing water or rain water can get from the roof to the switch.
- the sealed design of the switch is also important if the switch is designed, for example, as a load switch and a relatively high internal current is present, since incorrect contacting caused by contamination or humidification in this case leads to a serious impairment of the vehicle electrical system.
- the sealing membrane is preferably designed in the form of a ring, the large diameter being fastened in the housing and the small diameter resting on the periphery of the attachment of the actuating element which can be displaced crosswise and / or rotated.
- the small diameter of the sealing membrane preferably extends into a collar abutting the shoulder.
- a circumferential bead is expediently formed within the collar and lies in a corresponding annular groove in the attachment.
- the sealing membrane advantageously has at least one annular fold.
- the fold of the sealing membrane is dimensioned such that a crosswise displacement of the actuating element with simultaneous sealing against the housing is ensured.
- two or more leporello-like folds can also be provided.
- the sealing membrane is expediently fastened in a sealed manner within the housing.
- the sealing membrane can be welded or glued to the associated housing wall, for example.
- the sealing membrane is preferably formed in one piece with the housing.
- the sealing membrane can be manufactured together with the housing in a multi-component injection molding process. This ensures a reduction in the number of individual parts of the switch and does not require subsequent assembly of the seal.
- the switch comprises a housing 1 with an associated base 2 for accommodating a plurality of switching elements, the switching contacts of which interact with base-side switching contact tracks, an actuator plate 3 being provided for relocating the switching elements, into which an attachment 4 engages, which is connected to an actuating element 5.
- a seal 9 designed as a sealing membrane 8 is provided, which has an essentially circular contour.
- An edge 10 of the sealing membrane 8 is fixed within the housing 1 in a sealed manner on the housing wall 6 and extends in a pot shape over the thickness of the housing wall 6 in the direction of the actuating element 5 within an opening 11 in the housing wall 6.
- that of the actuating element 5 covered sealing membrane 8 provided with two annular leporello-like folds 12, which are spaced apart and open into a small diameter of the sealing membrane 8, which merges into a collar 13.
- the collar 13 rests against the shoulder 4 of the actuating element 5 under prestress.
- a circumferential bead 14 is formed within the collar and lies in a corresponding annular groove 15 in the shoulder 4.
- 1 guide means are provided within the housing, which either with the Interact switching elements or the actuator plate 3.
- the opening 11 in the housing wall 6 of the housing 1 thus has no guiding function, which is why it is circular.
