Abstract

Described is a switch assembly for a motor vehicle, comprising at least one tilt or slide switch, which has a switch housing and a shift lever, wherein the shift lever is tiltable or displaceable perpendicular to its axial extent, with an actuating head which is connected to an end portion of the shift lever, and at least one pressure switch, wherein the actuating head forms the housing for at least one pressure switch.

Description

The The invention relates to a switch arrangement for a motor vehicle, with at least one tilt or slide switch, a switch housing and a shift lever, wherein the shift lever perpendicular to its axial extension is tiltable or displaceable, with a Actuator button connected to an end portion of the shift lever is, and with at least one pressure switch.

Such a switch arrangement is known from DE 10 2004 058 127 A1 known. This document shows in one embodiment a combined push and slide switch. An actuating knob is connected to the switch tappets of two slide switches, wherein the switch tappets can be moved by the actuating knob in several directions of actuation. In addition, by pressing the operating button, the switch plungers are axially loaded with a force, whereby the switching elements perform pressure switching functions.

switching elements with combined pressure and tilt or slide switch functions are internally far more complex than simple tilt or slide switches and thereby relatively expensive.

It Therefore, the task was, simple tilt or slide switch to equip with particularly cost-effective pressure switching functions or known pressure and tilt or shift combination switch in a simple and cost effective way with additional Equip pressure switching functions.

These The object is achieved according to the invention that the operating knob the housing for at least one pressure switch is formed.

This At least one pressure switch can be particularly simple and inexpensive Way executed by a switching mat and a circuit board be. It is particularly advantageous if the printed circuit board is flexible Printed circuit board is formed.

Further advantageous embodiments and developments emerge the dependent claims and the subsequent ones Figures. The following is an embodiment illustrated and explained in more detail with reference to the drawing. Show it

1 a simplified sectional view of a switch assembly,

2 a schematic diagram of the switch assembly.

The 2 shows a schematic representation of a switch assembly according to the invention in a plan view. Recognizable is a transparent illustrated operating button ( 14 ) for operating two tilt or slide switches ( 1 . 2 ). The tilt or slide switches ( 1 . 2 ) each have a shift lever ( 5 . 6 ) whose end sections ( 7 . 8th ) by the transparent button ( 14 ) are visible therethrough. By drawn arrows are the possible operating directions of the lever ( 5 . 6 ). It can be seen that the first tilt or slide switch ( 1 ) provides a switch actuation in two directions of actuation, while the second tilt or slide switch ( 2 ) allows a switch operation in four directions of actuation. Switch actuations in the directions perpendicular to the longitudinal axis of the actuating button ( 14 ) by pressing on a longitudinal side of the actuating button ( 14 ). Depending on the position of the point of application of the actuating force is thereby either only one of the toggle or slide switch ( 1 . 2 ), or both tilt or slide switch ( 1 . 2 ) operated together.

If the pressure is applied to the side of the actuating button ( 14 ) approximately at the height of one of the shifters ( 5 . 6 ), the action button ( 14 ) as a one-armed lever with the shift lever ( 6 . 5 ) of the other tilt or slide switch ( 2 . 1 ) as a depository. Due to the distribution of forces, the actuation force acts more strongly on the nearest shift lever (FIG. 5 . 6 ), so that the corresponding tilt or slide switch ( 1 . 2 ) is pressed first. Is the pressure actuation approximately midway between the two levers ( 5 . 6 ), both tilt or slide switches ( 1 . 2 ) are operated simultaneously.

A common one Use case for the outlined switch arrangement exists in the control of a multi-part moving object, such as a motor-movable seat in a motor vehicle.

The 1 shows a switch assembly in a simplified sectional view. On a carrier plate ( 9 ) are two tilt or slide switches ( 1 . 2 ) arranged. The carrier plate ( 9 ) may be a printed circuit board, a stamped grid or other electrical circuit board, and serves except for mechanical fastening and for electrical contacting of the toggle or slide switch ( 1 . 2 ). Of course, on the carrier plate ( 9 ) and further, not shown here electrical or electronic components can be arranged and electrically contacted.

The internal structure of the two tilt or slide switches ( 1 . 2 ), which correspond to the 2 , be designed as two-way and Vierwegeschalter can not be shown in detail in the sectional view, as these details are of no relevance for further explanation and can be assumed to be known.

The tilt or slide switches ( 1 . 2 ) each have a switch housing ( 3 . 4 ) and a shift lever ( 5 . 6 ), which is the surface of a housing part ( 10 ) of a device housing not described in detail, penetrates. The shifters ( 5 . 6 ) are in the respective switch housings ( 3 . 4 ) slidably mounted or tiltable about a bearing point.

The free end sections ( 7 . 8th ) the shift lever ( 5 . 6 ), which may for example be formed as spherical or ellipsoidal projections, are movable on a frame ( 11 ), which is a part of one for both tilt or slide switch ( 1 . 2 ) common actuating button ( 14 ). The frame ( 11 ) is from a button cap ( 21 ), whose outer surfaces at the same time the accessible outer surfaces of the actuating button ( 14 ) form.

In order to be independent of the tilt or slide switches ( 1 . 2 ) To realize pressure switching functions, two pressure switches ( 15 . 16 ) into the operating button ( 14 ) integrated. For this purpose, in a free space between the frame ( 11 ) and the inside of the button cap ( 21 ) inside the actuating button ( 14 ) a printed circuit board ( 12 ) arranged. In order to allow a particularly simple installation, the circuit board ( 12 ) preferably designed as a flexible printed circuit board. A section of the printed circuit board ( 12 ) can thus by recesses of the frame ( 11 ) and the housing part ( 10 ) and at a junction ( 22 ) with the carrier plate ( 9 ) are contacted electrically.

On the circuit board ( 12 ) is a safety mat ( 13 ), which have several formations ( 19 . 20 ), which together with not shown contacts on the circuit board ( 12 ) each a pressure switch ( 15 . 16 ) train. The formations ( 19 . 20 ) are by recesses on the top of the operating knob ( 14 ) and close with actuators ( 17 . 18 ) in the form of key buttons extending to the outer surface of the actuating button ( 14 ) and can be operated there.

In order to is a simple and inexpensive way a pressure switching function in the operating knob of at least one tilt or Sliding switch integrated. The realization possible Of course, the invention is not limited to the illustrated Embodiment limited. So can the number the pressure switch integrated in the control knob Of course, free to the respective application requirements be adjusted. Likewise, the number is due to a common Operating button actuated tilt or slide switch freely definable. In particular, it may also be provided in one Actuator button, which is used to operate only one Tilt or slide switch is provided, a single pressure switch to integrate.
