Abstract

Excess speed warning control device comprises a housing (6) for a contact device wich has one movable surface (7) with elastic return properties, the displacement of which is related to a known vehicle speed. Motion is opposed due to the air resistance offered by the surface. An electrical circuit (5), coupled to an audio- or visual-warning system, is closed by the movement of a metallic plate (10) attached to the surface and which makes contact with two probes (51). The devic is attached to the exterior of the front of a vehicle, fixation points (2) being provided for this purpose.
