| 摘要 | The transducer (10) includes a casing (12) which defines an essentially L-shaped cavity having a substantially horizontal lower arm (16) and a substantially vertical ascending arm (18); a volume of mercury (A) which, in the rest condition, occupies the lower arm (16) and essentially does not occupy the ascending arm (18); an input electrode (30) which penetrates the lower arm (16) from the outside and is permanently immersed in the mercury (A), and a series of separate output electrodes (28₁ ... 28₇) which are spaced along the ascending arm (18) and can be reached in succession by the mercury (A) when it rises in the ascending arm (18) due to an inertial force directed along the lower arm (16) towards the ascending arm (18). The indicator (50) includes an elongate hollow body (52) provided with means (58) for fixing to the bodywork of a motor vehicle and carrying an array of electrical light units (92 1S ...92 6S , 92 1D ...92 6D ) spaced along its length. These units are aligned transverse the vehicle and face rearwardly with respect to the direction of travel. An inertial transducer such as that defined above is mounted in the hollow body (52) and its output electrodes are each connected to at least one of the light units. | ||||||
