Problems solved by technology

Free space must also be provided for the pivoting of the rocker when mounting the axis of rotation in the middle, which in turn impairs the tightness against the external medium and / or also isolates the light for the marking illumination of the rocker in the gap region become more difficult

Embodiment Construction

[0042] exist figure 1 A steering wheel 1 for a motor vehicle can be seen in the figure. The steering wheel 1 comprises a steering wheel rim 2 as well as steering wheel spokes 3 and an intermediate steering wheel hub 4 , in which, for example, an airbag can be arranged. Electrical switches 5 are arranged in the two lateral steering wheel spokes 3 for operating various devices in the motor vehicle, for example for a car radio, for a telephone, for a screen of a navigation system or the like switch.

[0043] Electrical switch 5 in figure 2 Shown in enlarged view. The switch 5 has a housing 6 and an actuating mechanism 7 designed in the form of a rocker. The switch 5 now has two such rocker-shaped actuating elements 7 , 7 ′ and additionally an actuating element 8 designed in the form of a button. The actuation mechanism 8 is surrounded by a fixed perforated plate 9 and serves as an actuation or return key. The actuating mechanism 7, 7' again has at least one actuating surfa...

Abstract

The invention relates to an electrical switch (5) having a housing (6), having at least one contact system (11) which is located in the housing (6) and having an operating element (7) which is designed in the form of a rocker and can be pivoted about a rotation axis between a neutral position and an operating position and has at least one operating area (10) for manually operating the operating element (7). The operating element (7) is prestressed into the neutral position by means of an elastic force. A centring pin (17) can be arranged approximately in the centre of the operating element (7). The elastic force interacts with the operating element (7) and possibly the centring pin (17) by way of a receptacle (19) in a dome (18) which is located in the housing (6), when the operating element (7) is pivoted, in such a way that the operating element (7) bears against the housing (6) on that side (20) of the operating element (7) which is opposite the operating area (10) so as to form the rotation axis (16).

Description

technical field [0001] The invention relates to an electrical switch according to the preamble of claim 1 . Background technique [0002] Such an electrical switch, which is used in the device as an operating switch, is actuated by means of a rocker. In particular, the operating switch can be used as a multifunctional switch on the steering wheel of a motor vehicle, for example for operating a car radio, a navigation system, a telephone, for gear selection of a gearbox, etc. [0003] Such an electrical rocker switch has a housing and at least one contact system located in the housing. To switch on the contact system, the switch has an actuating mechanism designed as a rocker, which is pivotable about an axis of rotation between a neutral position and an actuating position. The actuating mechanism again has at least one actuating surface, which is located on the side of the actuating mechanism for manual deflection and thus for actuating the actuating mechanism. The actuat...
