Abstract

Signaling device of the instant in which the mobile indicator element of an indicating device or analog meter, such as a speedometer, exceeds a predetermined limit position characterized in that it includes: a detection head incorporating two photo-electric detectors intended to receive the transmitted light, reflected or emitted to them by the indicator element, said photoelectric sensors being separated from one another in the direction of movement of the indicator element so that they are located on either side of a position corresponding to said pre-limit position. -determined, so that, when the indicator element exceeds said limit-position, the photo-electric receivers are successively subjected to a change in the amount of light received from the indicator element, which results in a difference in illumination of these receivers foto -electrical; and an electronic circuit connected so as to receive the output signals of the photo-electric receivers and capable, in response to these signals, of supplying a detection signal that triggers a signaling device when the indicating element exceeds its position- limit in a first direction and stop supplying this detection signal when the mobile element passes again by its limit-position moving in the other direction.
