ABSTRACT:
An autonomous device for warning drivers of automobiles of excessive speed of turning around a curve. The device is compact with both the sensing means and alarm audio and/or visual signal producing means. The sensing means comprises two, alternatively activated and differentially calibrated by means of a proposed calibration device, pair of mercury switches, each pair comprising two oppositely inclined mercury switches for monitoring right and left turns of the vehicle, wherein the first pair is adapted for use in conditions of dry road surface by calibration at a predetermined value of inclination and a second pair is adapted for use in conditions of wet road surface by calibration at a different predetermined value of inclination.
