Abstract
A vehicle level detector has a pair of switching elements respectively secured to a vehicle body and a suspension member for displacement with respect to one another corresponding to the displacement of the vehicle body and the suspension member. The switching elements are arranged to detect relative distance between the vehicle body and the suspension member and to produce signals when the detected distance is smaller or greater than predetermined minimum or maximum values. A fail-safe mechanism is provided to urge one of the switching elements to a position normally placing the switching element in relation to the other switching element such that the relative distance between the vehicle body and the suspension member is maintained within a range between the minimum and maximum predetermined values.
