SWITCHING DEVICE
First Claim
1. A switching device for keyless switching on or switching off of a load in a vehicle, and/or for unlocking or locking of components of a vehicle essential to function, comprising;
- at least one switching element arranged in a switch housing, which is operable by an operating element, so that at least one switching signal can be generated for a control unit,wherein an electrode is provided on a control unit housing, which is connected to the control unit, whereby the electrode serves for data transmission to a mobile ID transmitter and the electrode, through a capacitive coupling permits data transmission to the mobile ID transmitter, whereby the control unit sends a first coded, modulated, or coded and modulated signal through the electrode when it receives a first switching signal from the switching element.

Abstract
The invention relates to a switching device (1) for the keyless activation or deactivation of a consumer, especially an engine or the like in a vehicle, and/or for unlocking or locking a functionally essential component of a vehicle. Said device comprises at least one switching element (3), arranged inside a housing (2), which can be actuated by an actuation element (4), thereby generating at least one switching signal for the control unit (10). The aim of the invention is to provide a switching device which consists of only few components and which is incorporated into a keyless security system in a simple manner. For this purpose, an electrode (5) is provided on the housing (2) and is connected to the control unit (10). Said electrode (5) transmits data to a mobile ID transmitter (13) and the electrode (5) allows data being transmitted to a mobile ID transmitter (13) via a capacitative coupling (32, 34). The control unit (10) transmits a first encoded and/or modulated signal to the electrode (5) when the latter receives a first switching signal from the switching element (3). The invention also relates to a security system (25) for the keyless activation or deactivation of an installation or a device, especially of a steering wheel lock or of an engine in a vehicle. Said system comprises a switching device (1) according to the invention, and a mobile ID transmitter (13), capacitative data transmission between the switching device (1) and the ID transmitter (13) being possible, and a control unit (10) which controls data transmission between the switching device (1) and the mobile ID transmitter (13).
