Anti-theft protection for vehicles with an electric alarm system which is triggered by a switching device (10) which has a cardanically suspended annular container (50) in which an electrically conductive fluid (51) and a mass sensor (42) and switching sensors (44) are located which dip into the contact fluid (51) when the container (50) is placed in an oblique position and trigger the alarm. The annular container (50) is provided with a releasable clamp device (28) which is released before the system is activated, so that the cardanically suspended container (50) can adopt a horizontal position, and which then holds the annular container on the housing (11) under the effect of a spring element (29). <IMAGE> |
